I've been using an envirolite 200 for the last three years, and for all the indoor vegging. I use it for a space of 2x3ft, and is still very good output, after about 10.000 hours of light. When i change it, i'll choose the same, but this one still has life in her and the lumen output doesn't appear lower (although i haven't measured it), it heats very little and plants just love it. I had a 400 a few years before, (think it was a MH) for a slightly bigger space and the results weren't better.
Surely there must be other options, but this baby does her job dutifully, best 50€ i've spent in a bulb.
