Each light consists of 8 SI-B8U261560WW Samsung strips. 1 hlg-185h-c1050b, 8 .61" heatsinks from heatsinkusa 23" long. And 2x 1/2" x 18 inch u channel. Plus 1 1/2"x23" piece of U channel in the center to mount the driver. The U channel I buy 8’ long pieces from grainger and cut to size. The heatsink are connected with 1/2" long self tapping screws. The strips are mounted using double sided thermal tape. And you’ll need a small spool of 300 volt solid core 18 gauge wire. Plus wago connectors for the wiring. I use 9’ tool replacement power cords found on Amazon for about $3 for power cord. If any other details are needed just ask. The big key to price is ordering in bulk. 25 strips gives the best discount from arrow on strips. I order 26 make 3 big lights and 1 small 50 watt light with the extra 2 built the same as the big ones just a smaller driver.
No problem and like I said I’m here to help with more pics and step by step even if needed. Oh I did forget to add I use cased potentiometers from rapid led for dimming.
It’s the same diodes used in the v1 quantum boards. And running them at the level they’re on in my setup they stay pretty cool with the spread. I can say in my 5x4 room 3 of them on full power was almost a bit too much light. But light spread was perfect and penetration was excellent.
Interesting build article here. They hook them in parallel with a 48A constant voltage PS. (This doesn’t make sense to me because they are rated for 24.2 max V? @dbrn32)
It might be. But it works out to almost the same price only a few dollars difference so in my opinion I’d rather pay $20 or so more to get more efficient heat dispersion.
@WickedAle there are several build models there. I believe the 48v cv/cc driver build is using the double row f-series strips.
I’ve never ran the numbers on matching qb’s. But I believe running the single row f-series at 1050ma is about same efficacy as running v1 QB-288 at 2100ma. If you hold efficacy, 200 watts of strips would be equal to 200 watts of qb’s.
You can probably come up with low cost solution for that. Add some strips to where you need coverage at maybe a little lower power level than typical, and then dim your qb’s some.
The strips and the qb’s would both run a little more efficient that way, and you can hold or increase your intensity levels with similar or less power. You would also balance out your canopy intensity.
