This is my first DIY LED build and there's not much talk about these lights on IC so felt I should share the fun i've had recently. They are basically QBs in a strip running the same high efficiency samsung diodes.
As you see here, this rig is 99% finished, still needs a couple more bolts pinning her stiffer and final mounting wire and carabiners etc and thread lock on all the bolts then a final final wipe down.
8 X2 Solstrips (original one sided connector models) on a 1" x 1.5" Aluminium frame, bolted onto the 1.5" side. The heat sinks the strips are stuck to have a 1" space for mounting at each end leaving 0.5" free of the 1.5" side of the ally. On this driver (HLG 240 24a) the strips can only pull about 270 maximum watts between them I think so these strips can only pull around 33 watts tops and even with the dimmer all the way down it's insanely bright..
Pics say 1000 words..
You can wire these lot's of simpler ways than I have I wanted to try and hide them as much as possible so I bolted a 1.5x1.5x1.5cm U rail to the side with all the power connectors and then got an L shaped piece to go on top and hide the wires, which required tapping screw holes to mount. I used rubber grommets to protect against any wear on the wires as there would have been lots without them.
^ Wieland quick connectors for the power lead so the light can be really easily moved around if needs be. They're a bit expensive but imo totally worth it. I was also tempted to wire in a digital multimeter with a display on the top so I could see what the unit was drawing and how dimmed I had the LEDs but there was no point as running 8 X2s on this driver could only be within really safe tolerances for the strips, they can't be overrun on a 33 watts tops setup. I did a 7.5 cm gap in between strips, 10.5cm mounting hole to mounting hole, which is a bit close compared to how some have done theirs, I've got more strips on a lower wattage per unit for best efficiency and hopefully longest lives.
I used a mix of spectrums as you can see.. 4 x 3.5k, 2 x 2.7k and 2 x 5k for a total around 3.6K.. This runs very cool and is very bright. This is aimed at flowering and I want to make another couple smaller 6 strip vegging lights. This will do for a 3' x 4'to 4' x 4' area me thinks.
Best vibes brothers and sisters!
