no hate, use what works for you, They are going to eat up 10% of the light but thats not the end of the world if your coverage is better. Reflectors and lenses on cobs arent far off from that what metric makes ones better over another? ive never heard of duracell, im sure they are oem...

theyre made by osram generally i think the ratings on these are pretty solid, since they get bitchslapped by the EPA if they are found cheating Energy Star Ratings i go for whatevers cheaper, the Great Value at Walmart and EcoSmart ones at Home depot are under $5 ea do some simple math you...

depends on the driver. are they CC high voltage (cobs in series) or CV/CC low voltage (cobs in parallel)?

but that one's gold, bro

if that PPF reading and power measurment is to be believed 877.68/ (120*5.17) = 1.42 umol/J pass

prob 260-270 at the wall with driver losses
