I was saving up for a light from fluence, but @dbrn32 got me again with the diy bug.
These strips boast high efficacy and some great light spectrums. I needed to fill out a 3’x4’ footprint in my flowering tent. This is what I came up with.
10strips run at 1400ma with 2 hlg-185h-c1400 drivers hopefully putting me close to 400 watts at the wall for around $500
It’s on a 30”x46” frame and roughly follows the design outlined on their website.
This is a list of parts, it’s linked at their site.
The heat sinks are awesome, but took a while. They too were back ordered.
Be sure to order extra t-nuts and bolts. They’re cheap if you order them all with everything else… not so much if you forget and have to reorder.
So here’s just about everything I needed for the job.
There will be drilling, screwing, measuring, simple wiring, and basic assembly. Nothing is overly difficult.
The heat sinks require a hole drilled. I measured 3/4” from the end and marked the spot.
This is where you’ll add the screw and t-nut to attach the heat sinks to the crossbar, (which are also awesome).
I punch the spot to eliminate the bit from walking.
You will be drilling into the heat sink fins a bit, so be aware that bits break, (it broke on the last hole)
A little iso alcohol to clean off any residue. Trust me, there’s residue. Don’t skip this step. I also clean the aluminum side of the plc strips.
Apply the double sided heat sink tape.
The strips are 25mm, the heat sinks 25mm, but I couldn’t find 25mm tape, so I went with 30mm and trimmed it.
There will be some bubbles. I used a credit card to gently work most of them off the strip, and a push pin to pierce the bubbles that I couldn’t work out. Then gentle pressure to work the air out.
A little measuring, and then I placed the strips down. Firm pressure on the outer side of the strips. It’s aluminum, no worries, just don’t push on the leds.
Do this on each heatsink. I’ve got 2 strips /hsink. I alternate them.
The heat sinks are attached to the crossbars with screws and t-nuts. I use a little blue loctite. Nobody wants their lights to fall apart on their plants.
Measure, place heat sinks onto crossbars, measure again, and check for square.
