Custom veg only light

For heat sinks in the low power boards, I saw a poster on another board using aluminum yardsticks that he bought at a dollar store. I can’t find the post but he said they work pretty well for extracting heat with the added bonus of structural rigidity. Might be worth looking into. I did a quick google search and found some for under $4 online.

I used 48" long aluminum rulers from Harbor Freight as heat sinks, on L09 strips. Theyve been working great so far

even better. Perfect size for two of the two foot strips! Perfect use of a hobo freight tool

$5 for 2 heat sinks is hard to beat!

Yuuup I’m late to the punch on this one lol. Thanks for the tag @cobshopgrow.

@andreav-
I just built an all purpose light using 15 bridgelux eb2 280mm strips. 3500k since I’m vegging and flowering with them. I can’t say that I have any experience vegging with leds in a 5000k spectrum though.

my space dimensions are 40”x18” so I went for a HLG-150-20B to give me 30w per sq ft. I wired them up in 5 banks, three strips per bank. I’ve used 1/4” flat stock on all my strip builds and feel it works just fine. I understand the principals of a nice finned heat sink and u channel stock is much more efficient but my metal place sells flat stock for cheap so I went with that. I would recommend going with 1” width though if you do. I went 1.5” and she’s a hefty one. 1/8” angle stock at 1” width was used for framing. Also a 100k ohm 0.5w linear potentiometer for dimming.

The leds showed up after a snow delay. Got it all wired up and i dont know if i need a 2nd set for my 4 foot long area. Voltmeter says 19.5v power meter says 560mah.

8 leds zip ties to a cooling rack
