some interesting facts about LEDs L85 rating for cree LEDs is 28,500 hours http://www.cree.com/~/media/Files/Cree/LED Components and Modules/XLamp/XLamp Application Notes/XLamp_lumen_maintenance.pdf. T5HOs maintain 91% of their output after 12,000 hours and 89% of their output after 20,000 hours http://www.gelighting.com/LightingWeb/emea/images/Linear_Flourescent_T5_LongLast_Lamps_Data_sheet_EN_tcm181-12831.pdf. expert growers are able to produce 1gpw using HID lights. I am not an expert grower but I still have not found the magic formula that allows people to get 2gpw or more with led light. LEDs are expensive and PU MMJ grows are non profit.in my state I can give MMJ to another card holder if I produce more than I need but I can not receive any consideration in exchange for that gift. a little more honesty would greatly benefit many of us
