Flear.. I understand your trepidation about LED but I swear once you find the right one you'll be hooked.
Flint.. I have MANY LEDs in my house and NEVER had an issue with any of them.. even the small bedside tanks are all LED and planted. One great thing about LED is you do not have to replace.. unless you got a faulty one and in that case warranty should cover that. any other bulb should be replaced every 6 months but not LED.. and mercury vapor every 9 months. Visible light and usable light are not the same thing.
Good to know about the LED thing
most of what holds me back is a lack of understanding (when i understand fluorescent so well - or well enough to satisfy my curiosity)
as LEDs jump to PAR, and i really want to see a light spectrum map that matches a plants PUR so much more, instead what i have seen is really disappointing.
i just don't trust a single par number when a plants use of the light spectrum is shaped like an "M" ...
like the kelvin lighting number, there's lots of room for abuse of what light is given off by a single number, is it balanced, is it spiking in one area and just enough in another area to compensate and give it a total 6500K number. ... sure 6500K is a well known number that comes with some pretty serious expectations on what it delivers. this eases my concerns, but doesn't sooth them entirely
for LEDs and their PAR rating, ... i'm sure when i understand LEDs better i'll settle on a # but with the same trepidation about what that number means, ... and will always want to know more about how it fits on the spectrum map :)
till that day, ... yes, it's good to know there's hope :)
