Is it right to compare Led Plant bulbs against standard light bulbs?


I do not think it is right to compare Led Plant lights for incandescent lamps to grow plants not under ordinary light bulbs. If you do this comparison so you get a very large saving of energy/money than if one were to compare against the lights that we are hobby breeders typically use such as low-energy light bulbs and fluorescent lamps.


Here is an example:

Growspots with the best wavelengths for flowers and green plants. Replaces standard lamps which have 5-10 times higher electricity consumption.

Super Growspot 20W price: 1295:- = 125W lightbulb

If I do the same comparison with a standard low-energy bulb so it will be like this:

CFL 4000 k 30W Price: 39:- = 125W lightbulb

The skilljer only 10W in between compact fluorescent lamp that can grow in and Super Growspot then drag lågeneriglampan 0,6 times. more energy and there is a significant difference to the 5 – 10 times. Why not compare this instead?

VAT do you think that some Led Plant vendors make this comparison with conventional bulbs and why do you think they do.

Give me a comment I want to know what you think about this!

    I think that the whole system of labelling of lamps is clearly odd.. I've seen scary copy where 90w led corresponds to 600w HID etc.. What you want is the growing case 2 things.. Most lumens per watt of electricity and a maximum frequency tucked peak in the spectrum that you think best on.

    It had been clearly fun if someone decided to price comparison would be in pairs/W/KR

    Then there is the final problem that you will help us all with.. Numbers are not everything. To test the product.

    Yes it is a little weird all. There is probably no one who grow plants under a light bulb. Maybe hang it up they want to compare all the lights with incandescent bulbs and even these “hung with”. Now is the most incandescent bulbs banned. So now the comparison seems archaic.

      I have been given a promise by Anders Hammar on Green Light AB to change information so it will be more accurate. Hope it becomes a comparison with low-energy light bulbs and fluorescent lamps both T5 and T8 because it's these lights are the most common today for us hobby growers and those who want to have extra lighting of an individual flower. I think it was fair of Green Light AB to take of the criticism it shows that they are serious and are listening to their customers.

    HID lights provide much light output in frequencies that are not plant would have. LED lights can control the power to the light frequencies that the plant actually uses to create biomass and fruits etc.…..

    Instead watts and lumens can check for PAR , or PPFD
    Photosynthetical Active Radiation
    😉 the more you learn, the better you understand how little you really know….

      Hi Thomas.
      Well, this light is not so easy I know. Yes, of course it can be to point to control the effect of the light frequencies that the plant actually uses to create biomass and fruits etc. but at what price. But as sales pitches comparing Led lighting for plants with conventional bulbs, I think, is to deliberately mislead the purchaser to believe that to save a lot of money. To grow not in conventional bulbs then why compare against these?

    Just thomas I spinner on tiny only,
    PUR photosynthetic useble radiation is what you're after , Lumen is a measure of the human eye and tells you how much light it pumps out the plant cannot meet.

    where tex philips aquarelle closely followed by TLD840 is the best pipes available for reasonable allowance I mean in 50:-

    PPFD I think stands for Photosynthetic Photon flux density.

    • Stig Häggkvist says:

      Hey Jimmy!
      Well then I know what PPFD is but I'm trying to make this easy to understand for the uninitiated amateurs. That Lumen would not have any bearing on the plants I do not agree for sure is the difference if a light source emits 100 lumen or 1000 lumen to the plant but the light source must contain the correct wavelengths that the plant would have

      What you do to measure is micromoles photons per second and per square meter within the COUPLE (PPFD) But if I start to take up this so will not many to understand so I stick to simple advice that actually works.
