put 3200 mah in the calc and look at the f/v on the 1825.. this is why i want the 185-54 over the 48...unless the 48 can handle 55 voltswell what is "better"?
1812 is $6 cheaper per chip
1818 is ~7% more efficient but more expensive

1818 def a way better voltage profile for a hlg-48A driver if you want to run them hot
1812 will top out at 1250 mA/67W
1818 will go to 1900 mA/102W on same driver
(1825 goes to 2700 mA/145W)
your light is gonna get a plywoodboard. to sit in the middle of my 2 cxas on cpu coolers then im just gonna zap strap the drivers in a row and mount a clip fan above them for cooling... it'll look redneck as fuck. but it should be well isolated for shock.
as i mentioned it tops out at 2700 ma/53.5V on that driver, so yeah - you got it right for sure.put 3200 mah in the calc and look at the f/v on the 1825.. this is why i want the 185-54 over the 48...unless the 48 can handle 55 volts
Hey now there's an idea!! Lol Jk.you know how i know youre a fake redneck? no stolen aluminum street signs in your garage to use for heatsinks
i could use a heater core from my pick up and a cpu water block....i don't live near many road signs..so maybe im way more of a redneck than you think.you know how i know youre a fake redneck? no stolen aluminum street signs in your garage to use for heatsinks
if you look at the lm/w the 1825 is the best at that amperage. so if you get me a 185-54 ill buy your 1825 light "engine".. i might swap out the fan for a Peltier cooler to it .. to experiment.as i mentioned it tops out at 2700 ma/53.5V on that driver, so yeah - you got it right for sure.
lol i was talking with an riuer recently about the old days and he was like "im pretty sure my first growlight was a construction light stolen by my bros"Hey now there's an idea!! Lol Jk.
cmon man. i dont know many rednecks who run more than 4-6 deep on heater cores in their front yard, what you gonna do when you run out?i could use a heater core from my pick up and a cpu water block....i don't live near many road signs..so maybe im way more of a redneck than you think.
I'm sure a light bulb just went off in a few peoples headslol i was talking with an riuer recently about the old days and he was like "im pretty sure my first growlight was a construction light stolen by my bros"
the good old days where you doubled back around on your drive to the hydro store
That's the one i'm watching ATM! Apparently, i could run 10 1212's at 25w each. Can i cool these with your "105 mm Passive pin fin heatsink"?yup, you can get 150-160W out of it, still not a bad deal for $40
next step up are the $65 240 constant currents which will get you 250W or so
