standard 3mm tap on those

yeah i have a bunch, all 3 spectrums (vegmaster, full cycle, and bloom booster) how many are you looking for?

the pin fins are designed to radiate passively with the pins up. the heatsinks have extrusions in the top to mount a 50mm fan which would let you use them in any direction. i have a small stash of the fans, 12V iirc

in fact the site is due for a long overdue overhaul what products and services would you guys like to see? ive considered dabbling into the market of used components. photometrically tested with limited warranty thoughts? could serve two markets. those who want to upgrade, and the entry-level...

get yourself a kill-a-watt or watts up plug in meter to determine how much power you are actually drawing. way better than eyeballing

the active mechatronics come with multiple mounting options. there is a hardware kit with captive 1/4-20 nuts and you can choose to use either eyebolts or capscrews (both are included) also comes with M3 self-tappers to mount the cobs, grommet and clip for wiring

those are fine, but now im fond of the $20 shoplight led fixtures from walmart. does 2 trays right

either the 300L or 350R would crush a 3x3. and as somebody mentioned above 4 QB96.. the HLG100s i sell are like those, with mini-drivers. you can use a larger single dimmable driver to run all 4 as well, i have the 2.5x5.5 plugs that fit them

yes my tent with 6 diablos on 3 large heatsinks with a remote driver is essentially the same. hlg doesnt sell diablos as bare boards anymore, though i do.
