Hi guys.. I see what your talking about. From a longer term point of view dont the LED's last longer and save on electrical and additional material costs. Also as for lights with fans, wouldn't that be considered more mechanics to malfunction. My thought was that if the air is under full control via HVAC etc.. then theres no need for fans in the lights?
The problem with fans in the lights, any light, is that it's a place for humidity to get inside the light and screw up the board. It is just a matter of time.
Inda-Gro is IP-65 rated (weatherproof and gasketed driver housing) and the lamp is electrodeless so there is no corrosion going to develop on the sockets.
As to lamp life an Inda-Gro is electrodeless and rated for 100K hours with stable spectrums and intensities grow after grow. This is important if you're clones come off of mothers who sustain under the same lamps they'll be grown under. LED at best is rated @ 50K hrs and can be tailored to nail certain spectrums if that is your intent. I look for broad spectrum to better emulate natural sunlight and that runs contrary to what alot of LED mfgs make as their narrow spectrum claims to fame. Just sayin....
