Mate at 12,5 mm wide and capable of 9k @ 1.5 A,. the gen 3. if you put four side by side on a 50mm C section of aluminium you can output 40K lumens. for $60 and maybe $10 for the aluminium… 3 of these is MORE that sufficient for a square meter of grow space. What I have been doing for other peeps is buying a cheap ass Chinese psu and swapping out the fan for a decent one. As far as I can tell, so much of the electronic components integrated use the same supply chains components that are so integrated now that the difference of components is often minimal…so I swap out the shitty fan, whack a thermal couple cut out relay on it as a last resort and in 2 years have had not so much as a hiccup on any $70 36V psu’s
Bang for buck $14.81 USD for about 9K L: or say 40 K L per 50mm channel equates to $240 of full canopy light…
$40 bucks for the step up converters, $45 for the cheap PSU, $10 for the decent fan… $335 for a grow light that will be at least as good as anything shit you can buy. This is the headpspace it would good to get OG peeps IMHO. Fuck money making commercial sharks…share the knowledge like the old days…
