What is best for plant lighting is not always the most expensive solution. For my own part I am using fluorescent lighting with great success.
Led lighting are all very well but it is not better and not much more effective than T5 fluorescent lamps.
Choose lighting for your needs. Ärndu window grower to fit an LED ramp attached at the top of the Bay window well and provides effective directional light. An LED lamp in a stylish light fixture does well to highlight plants in the living room but select a lamp that does not have that nasty red blue disco light.
The red and blue LED light would be more effective a white LED's anyone reading about over all, but is it really so? No not in my experience a white LED light is at least as good and in some cases better.
Fluorescent and compact fluorescent bulbs that even it is a fluorescent lamps but in a different form to be effective must sit in a good light fixture so that the light is directed downwards. More fluorescent light fixtures work best in areas where you do not spend time daily.
To save energy by using LED as plant lighting is a tall tale. T5 fluorescent lamps does not draw more power than what today's LED lights do. Many believe that the LED is some kind of miracle lighting where you can insert 5 Watts and find out, for example, 40 Watt energy to the plants but it is of course not. 5 Watts is 5 Watts and nothing more, even if it has a blue and red light.
The higher the effect it has on its lighting, the better the growing plants. For the plants to get off to a good start in life so recommended ca. 100 watts/m2 and it is regardless of the type of lighting there are no short cuts.
Are you going to buy LED lighting for plants, so keep in mind that you get what you pay for. Ask how many micromoles/watts/m2 light gives it to you find out because otherwise you do not know how effective the lamp is. At least 2.0 micromoles/watts/m2 should the lamp deliver.
