Well I guess it just depends on the situation, but personally I have made the leap to mainly LED and definitely whites. But I grow in small spaces that need less heat accumulation.
But I also use Led bulbs in my home and other assorted areas and they do phenomenal, going 14 months strong. For a small space, some of the higher end led diodes can double the efficiency of CFL's. For me that is the kicker.
Even though I think cfl's have a great spectrum for plant growing and thousands of T5 growers can't be wrong. It is just progress I guess.
Led's are just getting started and are already functional, where will cfl's go?
....and as far as pollution, radiation, damaging effects, etc....Led light is not perfect, a lot of these red blue cheaper led's you see are a real strain on the eyes and undoubtedly the skin at close range, but some strains will love that.
The white led seems to be more benign in this respect, easier on the eyes [still don't look at them] and possibly easier on the skin.
The physical makeup of Led's is certainly more innocuous as well in the short term vs Cfl breakeage. Laws in the U.S., cite special disposal, but never if ever enforced with cfl's. Can't just dump them in the weekly pickup.
Where as the old led's being dumped into China and soon, the skeleton of the Bakken. They will eventually start to cause a long term problem when the materials start to degrade; which may be 100 years or more in Mediterranean type climate.
Pluss pluss minus minus
