correct, its not "magic" but it is marginally better than other cobs at the same price. Youre the one picking on 1812s so go find someone who sells them i guess. what greensea said... stop comparing apples and oranges.

its around. threads dont die here. 4 1212s beat a QB288. on the same thin heatsink which had the cobs at a disadvantage i dont have the new QBs yet (next week), but im thinking with the relationship i know between cobs, 4 luminus should be more efficient (and better coverage). themal...

was just an arbitrary example... i dont carry either 1812 or veros the cheaper luminus cxm22 beats them both

just a cursory look the 46W F strips are 168 lm/W but at twice the price... both have their applications, neither is obsolete by your metric vero D would be obsolete because vero C is more efficient. and vero C would be obsolete because citi 1825 is more efficient, etc.

current is an arbitary number , reread what i said please

1812s are gen 6, a current model cant comment on AFN but it seems your info is incorrect theres nothing a board can do that a cob cant if run soft enough

why would spectrum affect this?

nothing you can do with a spydr that you cant do with strips

thats a vague question certain wavelength ranges of uv and blue can stress a plant to create more resin but need to be applied sparingly

theyve got push ins like the other strips and boards. i only have a few of them heres a pic on 8-1/2x11" paper for scale

deficiencies mainly even when corrected you never get 100% of that vigor back

long day lengths at high intensity should be watched very carefully as problems run away from you in a blink of an eye

you wont notice a difference in quality

ill take some pics. they are 15 in a row, they are cutter strips

fair enough, not interested in the light so wont be bugging them. Just be aware there is probably a reason they are only giving half the specs and omitting the most important one

it should... says right there on pg 4 that an integrating sphere was used to measure total ppf.... but that info is conveniently redacted in the screenshots

its weird going into the LED section on other forums like ICmag - feels like stepping back in time like they are years behind RIU

Can you post the full report with overall umol/J?

not right now but i sometimes do volume discounts if you email
