Growing under lights

I've used them for annuals and tomatoes last spring and they worked like 
a charm - compact and strong plants, completely different than previous 
years with natural light at a west-sided window. I've never had any of 
the "classical" growing lights, so I can't compare to those.

No Idea if they work with grown up plants, but i wouldn't see why not. 
They do look funny though - everything's bright should switch 
to full spectral if you want to enjoy your flowers,,,
