Let's talk DIY lights

Oh and tax money ain’t even come yet :slight_smile:


I gotta get thinking about heatsink plates. I’m not sure what thickness to start hunting.

Running 560mm eb second gen strips at 700ma will 1/4 inch alum plate be sufficient?

Depends on size of plate and how many strips. Its usually pretty good though.

I’m thinking 23.5 l x 20w for 10 strips

23.5" x 20" x 1/4" is plenty big enough for 10 strips on hlg-120

Wagos plugs and board wire have arrived

458pm update: digikey has sent email strips and drivers have shipped tracking number included.


Getting the itch to build. Found plates 60 bucks each adds 300 to cost but will be overkilled for thermal dissipation

Just got my plates for 200 total light strips should be waiting for me when I get home


Hey @dbrn32 got my second set of two 288 v2. will running all 4 boards in a 3X3 1\2 ft area be too much? 8foot tall ceiling.

Twice as much as you need. Provided you have decent amput of reflection and not a ton of light spill anyways. Two boards on hlg-240 plenty for a 3x3. That’s what @MattyBear runs in one of his flower tents.


Learning to use the new lights is going to be a severe learning curve for me. The plants are drinking more under new lights, the coco dried faster than soil


Guess what’s here

Only waiting on thermal tape which should be here tonight

Thermal tapes not likely to show up tonight but that just allows me time to look at the lights in a few different configurations I’m thinking 5 pairs equally spaced will give best light balance and plates just long enough to mount drivers between lights without overlapping thermal signatures on the plate


They’ll drink and eat more.

Not sure the 1050 would drive that

Based upon my limited understanding I would consider the hlg-240h-c1400a

What are we talking about?

Was a cob posted with an 1100ma 51.5 fv rating with max a of 2400ma looked like 1100 was its lowest amp rating based on the post

Post got deleted and I didn’t save the cob link or I’d repost for ya

That would work fine. Probably even better than 1400ma in terms of electrical efficiency.

This is why I’m a rookie and your the master

Ha, I don’t know about that. Leds just behave a little differently than typical household type of load.

so I’ve made it as far as figuring out how the two big lights are going to hang and where the drivers will sit also decided on 5 equally spaced pairs of lights across each side of the board fairly productive considering I can’t build till the tape comes in

Tomorrow will have to pick up some bolts and nuts to mount the drivers so everything can be assembled and tested


Looks good! I think the driver slots are 4mm, but pretty sure the bolts I usually use are 8-32.
