There website blows IMO. It is unorganized and doesn't show other product like their T8 led bars that they have had for a year. You are best off, as many on here have done, is to call them and inquire
This is the only page that has anything worthy of reading and it is missing a bunch...
http://www.apachetechinc.com/cms.php?id_cms=4. The RW spectrum chart is for the R1...where is the R2's sheet? Like I said, the business side of the company is lacking but the products are legit.
Let me try and say as much in an organized fashion as I can about the AT120...
-120 1watt cree diodes driven at 100%
-Pulls 157w from the wall(120led+driver and fans)
-Ideal coverage is 2.5x3 but works fine in 3x3's
-1090umols @12" or 712umols@18"(recommended height)
-11"x13"x3"
-the WR2 is the best light and is for veg and ideal flower.
-The blues are obsolete now cause the white is a coated blue so the plants are getting all the blue they can handle other beneficial spectrum with the white chips
I am open to answer all the questions I can about the lights and their tech...or the company to the best that I can. I don't speak 100% for the company as I don't work there but they have given me certain privileges because I'm loyal and help them out with things and I have an online presence. Like a discount code for people(PM me) and the inside on what is happening(which is gold to a nerd like me. )
