Looking for a DIY LED Setup: How To Destructions.

Yeah I can see Frankenstein ,lol
lights look good too.

Shit diddnt see that better delete that lol that's what happens when your ripped

Agrees with reusing what you’ve got but if I’m going that far as to spread the boards out od just go strips which is even easier to get the voltage you want

The idea of bigger boards is to spread the diodes out more instead of cramming more in a smaller area which give better thermals which leads to more efficiency from the selected diodes.

Your factually correct but out of date, the existence of Quantum, strips etc was conceived around defeating the heat and efficacy ceiling of COBs, the issue today is we have efficacy, we have spectrum, what we need is EVEN coverage matched to higher efficiency nutrient delivery, 8 out of 10 led grows are performing sub par because newer lighting and nutrient delivery are not matched

Question. I'm downsizing a tent from a 4X4 to a 4X2 - I have 4 quantum boards (2 in parallel running off meanwell 48V HLG-240H-48A's) - If I was to run 3 of the quantum boards from a single 240W supply, I would expect the lumens per watt (and heat dissipation) to improve - would I get a brighter result, or would I just be better off running 2 harder?

These are the cutter units - marked aglite 001 - single colour units. Also running the red emerson boards too.

Or would I be better off yeild wise going back to CMH 315W units?

Not sure, but Id hazard to guess the 3 boards ran on around 80 watts each, would give roughly the same par than 2 boards ran at 120 watts Yet with a more even coverage and also extend their life with less heat.

Id consider running the 4 boards sideways spaced evenly with the 2 drivers in a 4 x 2, dimmed to 75% max.

240 watts in a 4 x 2 is maybe a bit light on unless you've perfected everything else.

480 watts is obviously a bit much though. Sweet spot probably somewhere in the middle.

I managed to get over a pound from the 4X4 with 480W - it was this setup - https://www.cutter.com.au/product/solskin-single-channel-4x4-kit/ - The main concern is the cooling issues coming into summer.

Keep the power driver outside tent
