Recently received some quantum boards for a christmas gift i have 3 qb120s 2 5000k 1 4000k and 1 qb288v2 3000k and 1 qb288v2 rspec i am so lost in all the techical specs i just need a link to a decent double heatsink for the 2 qb288v2s wanna run em on the same fixture also need to know what i need specifically for drivers or if u can possibly run both boards on the same driver? And i would like to use the 3 qb120s as a veg fixture i was told they dont need a heatsink but id like them on a frame or something and need to figure out the best driver/drivers to run that as well @dbrn32 PLEASE HELP ME hahahaha:rofl:
You can get the heat sinks from the HLG website. They are predrilled for your boards. I am still learning the electrical side so I won’t guess at what to do there. I have a good idea but want to wait and see how it compares to the experts advice. Plus I want tos we if I’ve learned anything from him.
Hlg isn’t an approved vendor, but that’s where you need to go for a pre drilled heatsink. You could maybe make 5.886 from heatsink USA work, but I doubt it would be much cheaper, and would take a lot more labor.
For the qb 120’s, that’s right you don’t need a heatsink. You can build frame out of aluminum angle, probably 1/8" wall x 3/4". Coincidentally, you probably want the same driver for the qb 120’s. The hlg-240h-c2100a will run 3-4 qb 120’s. Next smaller driver isn’t available in 2100ma output current.
Driver for two 288 boards you want meanwell hlg-240h-c2100a. DO NOT get a constant voltage driver, the forward voltage on those 2 boards is different.
If you need anything else let me know.
Sweet so i found a double heat sink and am looking for a good deal on 2 of those deivers now like you were saying about constant voltage drivers how do i know the difference haha sorry about the silly questions but im clueless about diy qb lights lol im learning haha
Constant voltage driver would look like hlg-240h-48a. If you get driver I posted above you’ll be in good shape.
Thanks a ton brotha one more question do you have a good place to find some aluminum to build a frame for the 120s wanna use tge 3 for a 4x4 veg area
Check grainger or anything like that. If not, local home improvement stores will probably have it.
Anyone got any ideas on the best way to frame 3 120s to cover a 4x4
Not really enough light for 4x4 coverage. You could do 3 in a row and would be decent light in a 2x4.
Ok gotcha brotha thank you what do you think i will i need for wire and connectors to build the qb120 veg light and the qb288v2 flower light?
My wife just talked me into giving her these 2 lights she wants her own grow space so shes ordering a 2x4x6 tent and these will be her lights she says thank you @dbrn32
She will do well with them. I would get something like 25’ of 18awg solid, should be plenty for two builds.
A 10 pack of these. They make assortments too, not bad to have around if you don’t mind spending extra couple bucks
These aren’t needed, but make nice clean connection to power cord.
And you need a power cord for each fixture. You can hack up 16/3 extension cord if need be. I have link here for 3’, just make sure to get long enough to suit your needs.
