My new purchase of a 300w (190watt actual power draw) 10 band led arrived today. I am very pleased with it thus far. It is very bright. At a foot away my light meter goes nuts and gives a reading that is off the charts. I find that there is not very much information about the actual foot candle intensity that is needed to grow orchids with leds as the main concern with them is par (I don't have a PAR meter). Hopefully I don't fry my plants in the learning curve.

my room looks like a whore house because it is now a most beautiful shade of pink from this behemoth of a light. Not the best for viewing the plants, but the ten degree difference in growing temperature and the ability to more fully enclose the case to raise the humidity more than makes up for the alien shade of pink that is coating my room.
I'll keep you all posted on how the plants respond. I plan on buying a PAR meter to make this a more scientific experiment. That way I can take measurements of how far away the plants can be grown from the light and still bloom.
Bye for now.
