Hello Steve,
After some researches about this method to give light to plants, it 
seems that a lighting only by led is not very well to spectrum level 
(problems to red levels and without these ray the plants have not a 
beautiful growth ; I had the same problem in my system 
http://fradnai.free.fr/GB/vitrineV2.htm). I have done these researches 
because I use artificial lighting for my indoor greenhouse. In more, 
obtain a large surface of light by led is not easy and it seems that to 
obtain these conditions, the price of install becomes then expensive 
(for me here in France with the price of materials). But it is also a 
very interesting method, perhaps a little difficult to use to a personal 
use out of professional in reason of price to have an optimal tool 
(material / spectrum / cost). So after these observations, and for me, I 
have decided to use fluocompact light and grolux tubs with electronical 
ballast, more easy to use and cheaper for me (I had tried Envirolite 
light too, but the results were no very good to my opinion, and now with 
fluocompact light and grolux tubs it is better, without etiolation and 
plants make flowers. Build of my indoor greenhouse 
and aspect of my lighting installation 
I must place one grolux tubs in more. There is 2 fluocompact light in 
6500°K/23W, 2 grolux tubs in 18W and I must add 1 grolux tub in 36W).
See you
