Build your own plant lighting lamp for under 200:-

vad_ska_detta_bliNow I have picked in hop a plant lamp consisting of a stainless steel Bowl from IKEA (shiny shiny 28 cm) a little electrical cable and a lamp holders, switch and a low energy light bulb from the auto parts store on 30W 4000 k and tested the (Light metering)



My measurements showed these results.

707 Lux at 0,5 metres above the plants, surface approximately 1.3. o square meters
2363 Lux at 0,2 metres above the plants, surface approx. 0,5 square meters

In order for a chiliplanta to clear his life must get 500-600 Lux under 12-16
hours per day. Would it be chiliplantan to thrive so well that it develops
and grows large, light intensity values produced shall lie between the 700 and 1 000 Lux and clear
This home fixed plant lights if you don't place it higher up than 50 cm
from the top. You can also use the 20watt and 15watt lights but then the effect is smaller but the hands well o well to wear over their small chiliplantor.

This lamp is perfect to wear over seeding by chiliplantor.

PS. When a low-energy lampas setting becomes quite warm so it is best to use a fixture that can withstand high heat!

Here is a little video on the built-in!

    Stumbled across this when I was looking for other sources of light at work.
    They are nothing you have tried in your farming or? 🙂

    It was that T5 / T8

    • Stoffe says:

      Failed to edit post you will answer my own 🙂

      Fans also Grolux tubes with blue/red radiation T5/T8

      • Stig Häggkvist says:

        Hi Stoffe.
        No I have not tested these tubes that you mention, but it is most “common” a little cheaper consumer concerns which I test when many survey has shown that the special plant lamps available in different brands is not much better than standard tubes.

        Well I have a T5 special that I actually test and it's Pro Light grow 54W and 24W but it is because they are original in LightWave light fittings but I have not seen that they would give better results than standard tube with the correct kelvin.

    Thanks for the inspiration!
    After reading your guide to build this simple lamp I went to IKEA to buy Bowl.
    When it was over I found a bucket that I bought home instead.
    Here you will find a picture:
    What do you think, will it work just as well ?
    Am a bit worried about the heat coming from the lamp, It can be negative ?
    Best wishes,,

    • Stig Häggkvist says:

      Hello Fredrik

      I saw your solution with a small bucket and it was really nice. If you are concerned that it would be too hot so one can drill some hair at the top of the bucket so it becomes a bit more ventilation around the lamp but I do not think it is necessary. Yes, this light in different colors could probably be a hit 🙂

    • Freddie says:

      What did you buy for color? You can buy the spray-paint on the tex Biltema? Thought so it can withstand ev heat.
      best wishes,

      • Stig Häggkvist says:

        Hi Freddie! I don't know what you're going to have to? Do you want color that can withstand heat so there is heat paint that can withstand up to 600 degrees on the spray can, do not know if the auto parts store have it but it's there they sell car accessories.

  3. Micke says:

    I bought the wrong CFL from auto parts store. They would be on 30W 4000 k instead became the 45W 4000 k. And now I wonder if it gets too hot for chillin. I will have your IkEA lamp.
    And what kind of lamp holders to use in light they were so many to choose from so there was no lamp holders for me

    • Stig Häggkvist says:

      Hello Mike.
      You can use the 45W 4000 k it gives more power so you can have it a bit higher up than the plants. The heat shouldn't be any danger. The best is to have a bakelite holders but it goes well with biltemas black or white lamp holders for E27 composure as it is on these low-energy light bulbs.

      • Janne says:

        Hey Stig.

        How much higher do you think appropriate, with 45W?


        • Stig Häggkvist says:

          Hi! Do you mean how high above the plants, or do you mean the actual shade depth. The height of the plants with the 45W. It goes to the bigger screen of a 45w lamp then the otherwise stand out off the screen and then it will be the direction of the light downwards significantly worse.

          • Janne says:

            Thank You Stig, It became 30W.
            However, I get a lamp holders that allow 30W lamp hanging down a bit further below the screen.

            Thank you for a great page Path, to a lot of help for a newbie like me.

            MVH janne

  4. Freddie says:

    Hmmm if I check at auto parts store o other pages it is 2700 k on low energy lamps??? Or I look wrong?

    • Stig Häggkvist says:

      Hi Freddie!

      Biltema has only CFLs 4000 k in 30W and 45W they should be on their website.

  5. Ellis says:


    This lamp works also for chili to be kept indoors over the winter?
    In the process of trying to find a low-budget option in this lampdjungeln available.


    • Stig Häggkvist says:

      Hi Ellis!

      Yes it works excellent for wintering of chili. You can keep the few pieces with this 30W lamp if the lamp approx. 30 – 60 cm over the plants and highlights at least 10 hours/day

  6. Sebbe says:

    I am on and searching for any of the mentioned LEDs with light color 4000 Kelvin but just as “Freddie” wrote in an earlier comment so there doesn't seem to be any other than those with 2700 K anymore?
    It must be 4000 Kelvin or does it work with those with?

    Then I wonder, If we can imagine to slide a bit on this with the low price tag, It would work to establish a couple three pieces of this type around, or would the light from this variant with fluorescent lamps cannot be sufficiently?

    Thanks for a great guide!

    • Stig Häggkvist says:

      Hi! well it can be found at auto parts store ask for fluorescent lamps and compact fluorescent lamps with kallvitt light. No 2700 k are not good for warm light.

      • Lena sandeberg says:

        Hey Stig
        Sitter o look at auto parts store o fluorescent lamps ..
        I can not find them at all, the ones that you say exist. Have you ev item No.?
        I'm pretty damn building fancy light bulbs so we can bring in our darlings from the balcony.


        • Stig Häggkvist says:

          Hi! Fluorescent lamps can be found here. These are Daylight-White but it really doesn't matter which colour you are using. I have tested with warm white State-and it goes just as well with. And CFLs 30W has article number 44275

          • Lena sandeberg says:

            Hi again o thanks for the info!
            Found * finished lamps * now taken only low energy lamps . It becomes somewhat jealous of all these crops and shows on facebook.
            Thank you Path for our new interest(When it goes over to the madness? )

          • Stig Häggkvist says:

            Glad you found lamps. good luck with your chilisar.

  7. Hey Stig.

    I was going to build something similar. All lampholders designed like that, or do I need to order a special model?

    Am I on the right track with this:

    • Stig Häggkvist says:

      Hi! Yes that works but you do not need to have the ring and with threads there is a cheaper model but this.

  8. Roger says:

    Hey Stig!
    Confusing this with lighting, can this kind of work now when I want to drive up chili- and citrusfrön indoor?

    • Stig Häggkvist says:

      Hi Roger! No nothing to push up the plants with. A Lampshade that you put a CFL in at 4000 k or 6400K is the simplest thing that works. There is too little power, energy in the light you are linking to.

  9. Roger says:

    Thanks for the reply Path!
    I have now bought a LE lamp on Kjell & co 36 W 6400k 22oo lm. Cost only 99 KR. Even found a Lampshade on the ants for a femtiolapp. so now the grown chili!

  10. Regina Säveholm O. says:

    Wondering where to get the type of lamp to use this? DOM I found you have to make much bigger holes for (over 40 mm diameter) to be able to mount the screen.

    • Stig Häggkvist says:

      Normal E27 lampholders hole 10 mm. You buy a tractor loader with ACP plastic external thread it is the person sitting in the hole.

  11. Peter says:

    Have you built any homebuilt light fixture for fluorescent Path?

    • Stig Häggkvist says:

      Hi! No not yet but it is in the works. This fall is my ChiliLight but T5 fluorescent lamps.

  12. Peter says:

    What will it cost at a hip like that?

  13. Peter says:

    I have built two such lights and they work fine. I have hung them around 30 cm above the plants. The plants are about 7-8 days after germ. The leaves pointing almost straight up. What is this a sign of do you think? Are the lights too close?

  14. Delia H says:

    Hey Stig. Yes bow and thank you for your tips
    Yes wondering if it can be used to drive by tomato plants

    • Stig Häggkvist says:

      Hi! Yes it is possible there is not much difference on tomato plants. I also runs up the tomatoes but I don't until March, There is no reason to start with these too early
      then they grow quite quickly.

  15. Therese says:

    I was going to try building this lamp to my chiliodling.
    But seeing that your lamp has expired. Do you think it works just as well with this from auto parts store?

  16. Felix says:

    A lot of questions here but was wondering if you know the length of such a lamp fixed 45w?

    You can this with growing 🙂

  17. Jonas L says:

    The plastic mat with raised edges, you have your plastic jars standing in. What is known as a kind and where can I get hold of a?

    • Stig Häggkvist says:

      Hi! It is a kapilärmatta that the pots are on available on the meter at there are also ready-made trays with carpet “Irrigation tray with vattenreservoir”

  18. Rickard says:


    The bright light may have? I have a lamp that provides about 9000 Lux at 50 cm. It has the following wavelengths 430 ~ 440nm, 450~ 475nm 620 ~ 630nm, 650~ 660nm, IR, and white light.

    It becomes too strong?


    • Stig Häggkvist says:

      Hi! the light is probably not too strong so there's no danger. INFRARED is light on 700 NM and is a light that we can't see with our eyes.

  19. Jenny says:

    Hi! Which is more important? Kevin lumen watt…. trying to find some “ok” lamps with E14 attachment instead of e27. So I do not have to build 😉

    • Stig Häggkvist says:

      Hi. I think you will be fooled by this value (8 W = 45 W) The lamp is only on 8 W. What do they compare with that light as a 45 W-old light bulb and it is quite another. light on 8 W is far too weak to push up the chili with sorry. It would be absolutely wonderful and very economical if you could submit 8 W in the lamp and get out 45 W energy into their plants but unfortunately there are no such lamps. You need to check on the power light is on and does not look at how much light it provides when compared to an old light bulb.

  20. Daniel says:

    The lamp you recommend does not appear to be sold anymore. The strongest I can find at biltema's website is located at 20W, does it work? Do you have any other recommendations?

    • Stig Häggkvist says:

      Hi! No Student shall change providers so I do not know if or when it will enter new. Please let me know via the contact page to me so I can arrange a replacement lamp for you.

  21. Anna says:

    Hi! I'll drive up some plants indoors now in our. Including some perennials and tomato. I want to have some type of lighting to these but have these kinds of problems to find something that fits. What kind of lighting is required for them to be able förkultiveras indoor? Do not spend any large sums, have used Biltema 30w 4000k for wintering and intended to use them for förkultiveringen but they do not seem to exist.

  22. Anna says:

    Perfect! However, another question 🙂 thought buying a luminaire 2 with x 36W 4200K. Wondering if this is excessive lighting to power up my plants. How far will the 1 x 36w for example? How far from the plant should the lights be so as not to burn them? Can't find the lumen of these on Biltemas page so I don't know how strong the light is.

    • Stig Häggkvist says:

      Hi! It is always better to have too much than too little power. 2x36W is good lighting for about. 1 M2. Lumen, do not bother because it has nothing to do with växtljus. It's better to count on Watts the higher power you have, the better the. CA. 100W/m2 is a good benchmark. You can have the lights about 20 cm from the plants when they are small. It is not very warm under fluorescent lighting, feel with your hand so you know how hot it gets

      • Anna says:

        Hi! Have mounted up the lighting now but discovered that it get really hot in fluorescent lighting? Getting around 26-27 degrees for the plants. Is this ok? Thinking that they might be rickety?

  23. the beginner says:

    Hi! I purchased bulbs from auto parts store at 4000 k they illuminate very blue in comparison with those in your video. But to my question! There were only 20w so I bought three works that add up to? Now my plants 1st plant lamp 8, 5w bluish-red led + 3St. 20w compact fluorescent at 4000 k. In the case of 5 plants and all bulbs are between 10-25 cm from the

    • Stig Häggkvist says:

      Hi! Yes it works to put together several lamps. You have now and it's about a total of just 68W to illuminate an area of 0,5 M2

  24. Josefin says:

    Hey Stig
    Thought for the first time test plant lighting on my chili- and tomato plants when growth phase been so tough the last few years due to bad light. Unfortunately, not the lamp spreading remain and I am trying to search high and low for similar options that can work, do you have any other tips? Have read through all the comments but seem to not find anything there is to get hold of. As I understand it, they need it to be at least 30W, 4000k but is unsure what lm need be.

    Many thanks in advance

    • Stig Häggkvist says:

      Hello Josephine. It offers good lights on 45W Low-power 45W 6400K These lights work great. In terms of lumens/lux, you do not need to worry as there has not been anything but växtljus to do without it, the effect is you look at. A 45W lamp in good reflector is sufficient for approx.. 0,5 M2.

      • Josefin says:

        Hey Stig! Bought the bulb you told us about, and test a while, but it seems almost as if it burns the leaves of the plantlets. And even on my big aloe vera which is beside. Should I then just try to move the light further away or do you have any tips / ideas on what the problem might be? Mvh J

  25. Mattias says:

    Hey Stig,
    Even thought I try to get some type of lighting to my chili- and tomato plants.

    Compact fluorescent lamps have been found at auto parts store on 36W, 4000(K) that should work (44259). However, the 2G11 socket and I have not been able to find any light fixture for these.
    Have also found a cheap fittings for T8 fluorescent lamps on auto parts store (443911) for two 18W fluorescent lamps.
    They also sell these lamps (44775) at 18W, 6500(K).

    2x18W should hand power wise? The color temperature is also ok I guess. But how damn freezing cold is not a light at 6500 k? Is it possible to be in the same room during the time the light is on? Have supposed to have plant lights lit during the day when we are not at home. Or highlight it on the night?

    Thanks for an interesting side!

    • Stig Häggkvist says:

      Hi! Färgtempen does not matter it is possible both with hot and cold light. Urban lighting from morning to night 14 – 16 hours is just right

  26. Daniel says:

    Stig! I have built this lamp, and irrigation of the box of ikea-box. Downloaded pvc plastic(Forex?) at skyltmakaren, got 3 mm. Tested heat this plastic to about 80 degrees, 10-15 minutes and got an incredibly lättformad plastic that became rock hard in ca 45 seconds! This soft warm PVC piece I added around lampskålens edge to get light adjuster/glare shield at the bottom for lampbiten that stand out, was that done on purpose!

    Wanted to tell about PVC trick for one can shape very fun with it, direct lighting including. But have the fan on for it smells a lot and can certainly contain some gases… 🙂 I also think that the plastic became stiffer afterwards.

  27. Marten says:

    Also bought the light source from Ikea, LED, 1800 lumen, 22W, 149 KR. Apparently a novelty in their catalog, have you/anyone else tested such a lamp?

  28. Oskar says:

    Thanks for nice post!

    What is today's options now that auto parts store stopped selling?

  29. Springs says:

    Stig, I need your expertise. I am looking for a suitable light source in order to cultivate Gotu Kola (CENTELLA leaf) from seeds. I've been meaning to use a lamp with E27 socket. Seeing that many energy-saving lamps disappeared from the stores ' selection last time. Is it to make room for LED?

    • Stig Häggkvist says:

      Hi! Many cheap low energy has disappeared, as had the auto parts store, tex. But there is everything from 45W to 125W with E27 composure which is good. Please get in late October via my contact page and I'll arrange something good for you 🙂

      • Malin says:

        What should I consider when choosing a lamp? I suspect that the LEDs are easier to get hold of these days? What watt, lumen and kelvin?

        • Stig Häggkvist says:

          Hi Malin! It's watt you should go by whether you choose led. 100W m2 has a surface of approx.. 50×50 cm so hand 25W

  30. Mats Sundelin says:

    Hey Stig
    Good idea but GROUND the LIGHT of SEVENTEEN OLD MEN

    I happened to stumble across this when I searched for ideas for building your own light and can't help but comment on electrical safety this.

    It is deadly not to ground the light because it has steel screen and you drag in strong current.

    Alternative, find a plastic bowl with blank inside or put foil on the inside of the Bowl any time.

    • Stig Häggkvist says:

      Hi! There is no way for the screen to be energized when the wires going into the bulb holder which is made of plastic. I've checked out the other lamps with metal screen such as desk lamps, etc. and they have no grounding in the metal screen. Grounded is always best I know then I build other lamps with fluorescent lights and there are screen in metal grounded.

  31. Denniz says:

    That great idea that I built a custom!

    However, while I was at IKEA so I checked their lame parma tours and found this:
    See 25, 38 and 50 cm diameter. I chose 25 cm, and it has maxwatt 60W.


    Using the Swedish work environment authority's own app to measure light, It's called “Light”. Certain, It certainly has a large margin of error, However, measuring them very much like repeated measurements on the same exact location. (turn on 500 Lux max)

    So I tested the lights at 10 cm height (lower lampspetsen to a table):
    IKEA DIY Bowl: 4500-5500 Lux
    IKEA PHOTO 25 cm: 9000-10000 Lux

    I also switched the lights to eliminate the lack of individual lampkvalite and got similar results!
    The lights are low power 30W Sartano 1650 lumen from Harald Nyborg 49kr and were brand new.

    This is because most likely that with IKEA dish stand lamp out approx. 6 cm and with IKEA Photo only 1 cm. As more light is reflected with IKEA Photo. The inside of the Photo is Matt White.
    The question is if I had drilled a 30-40 mm hole in the IKEA dish, then I had been able to obtain similar (the lamp stands out 1 cm) with IKEA dish. However, I have not any electric drill/tool making so big hole.

  32. MIK says:

    Hey Stig,

    Now of course this thread kept going a few years, so I understand that you have had the opportunity to learn new things. It gets a little confusing to read the entire thread from the beginning. In the first post, specify which lux-values that are necessary and the first comment, reply to the correct kelvin is important. In later comments, say that neither lux or Kelvin matters without just about Watts.

    Can you explain why Kelvin and lux are not important – or link to the appropriate info page?
    Or maybe a book I can find at the library? 😉

    (I'll need a lot of new lighting and would have liked to use LED. Other sources tell me that they go well, but you should go after Watts so vetefan…)

    • Stig Häggkvist says:

      Hi! You are absolutely right I've been learning new things about how växtljus works. Both through its own tests and my contact with the researcher Karl-Johan bergstrand at SLU (Swedish University of agricultural sciences) I will of course change and denounce the new skills I gained about växtljus in my thread.

      Your question about kelvin, and lux I sent on to Karl-Johan here is his reply:

      Kelvin and lux have to do with the human eye, Kelvin with colour vision and lux with "bright idea". Because our pupils adapt to light so it becomes misleading to plants. Lux takes most account of green light and cover almost not at all wavelengths in c:(a) 450 NM and over 650 NM, i.e.. you miss a lot of light which the plants have the advantage of.

      Kelvin is not an absolute measure but same Kelvin numbers can be achieved using many different combinations of Red, Blue and green light, i.e.. It says nothing about the quality of the light, but just how the human eye perceives light.

      The human eye is a very bad light sensor.

      Best regards


  33. Gustav Almer says:

    Hi! I was thinking of getting a large lamp 300w with blue light at 6500 k but after perusing the blog I have decided me to buy 4 x 30W lamps with cold white light instead (as well as building an armature) I'd rather that they should be at 4000 k. Now I wonder if you have any tips?

    I am experiencing some confusion here and on other pages, one on one, you should have the white light that are 4000 k because they contain all wavelengths since seems Kelvin did not play any role and a blue light on the 6500 can va as good and contain all wavelengths. I don't really understand this.

  34. Maria says:

    Hi! Funny thing, and that thread has been running so long.

    It works to paint in and outside of the Bowl?
    Or does it have something to do with it to be blank on the inside?

    • Stig Häggkvist says:

      Hi! Paint the white on the inside, it is okay for white reflects light well. Other colors are not so good.
