CLU058 grow update

A few years ago I decided that I wanted to grow more efficiently with a lower impact. I found this forum and read a lot and decided to switch over to COBs.

I built an 8x20 no till bed and built a pretty large COB array sourced from cobkits.

My setup is: 96 x CLU058 1825 chips powered by 24 x HLG-240H-C1050 drivers... running the chips pretty soft on 133mm passive pin heatsinks.

I just wanted to pop in and say that these things have worked amazingly and I am growing the best flower I have ever grown with much smaller electric bills and nearly 0 nutrient costs.

I recently reconfigured my space and with two 4x16 grassroots fabric raised beds and cleaned it up some. Just wanted to say thanks for all the great information. My next project will be a 2000w strip build with Samsung F series strips. 20181124_122039.jpg 20181205_232307.jpg 20190110_231838.jpg 20190130_184649.jpg 20190223_092620.jpg 20190303_210446.jpg 20190425_162158.jpg

Nice setup. I have 8 of the Clu058 cobs that someone bought and decided against cobs. And traded a bunch of strips from me for. I may hook em up n see how they do. Lookn good on here. That is a giant no till bed. 96 clu058 cobs I bet set you back a few pennies at $70+ each.

The whole setup was certainly not cheap. I could have set up the room with 8 HPS lights for less than 1/3 of the cost. I've got a total of 5200w in there and feel it is at least equivalent to 8000w of HPS.

Here are a few leftover COBs from the original build finally getting put together for veg two years later.

The finished one was in use for a while on a single 4 foot frame, but was in a corner of the garage hence the grime on it. I reconfigured it for a small veg space on an 18x22 frame. I'll have to clean up the wiring. BJB holders are single use at the connectors if memory serves correct though I've had an incidental wire or two pull out and go back in fine.

As with the last fixtures, these are CLU058 1825s driven at 1050ma for around 210w each.

nice, i still use my 058 rig

the luminus cxm22 are more efficient than the gen5s and less than half the cost, and more durable imo. have had lots of returns on the gen 6 058s with rows out (and almost none on 048s)

larger chips def more delicate

I had to look back to check what I bought. These smaller rigs are gen 5s, in the big room I've got 80 gen 6s and 16 gen 5s sprinkled in. All 3500k. I havent noticed any issues with the chips, but I havent checked closely either.

I'm definitely going to build put some cxm22s at some point. Like I said, next round is a strip build, but I've been intrigued by the luminus chips for a minute now.

Also, for anyone wondering, I pulled wires from the BJB holders to clean up my wiring and they wouldn't make a connection afterward. I had to swap in some I had lying around. Gotta order 4 more and some screws I guess. @CobKits what size screws are used to mount the holders to the heatsinks?

you need to dim the chips down to barely lit to see the rows out. or look up with welder mask

screw size is depended on what the heatsinks are drilled for. M3x6 or M3x8 most common

bjbs are typically not reusable, if you unmount them and twist and 'unscrew'' them, you might get a second use out of them. if you pull hard to pull it out axially, i wouldnt trust that holder in reuse

If you are running more than 150W then I recommend bender and wirth holders. The plastic holders can not take the heat put out from the photons properly. They get too hot for the plastic to handle. I addressed this 4 years ago with bjb but they have done nothing about it. They actually didn't take any consideration at all about the heat from the photons and the effects it will have on a holder.

I'll look into replacing with the B&W holders for this last fixture. I've been running these BJBs for 2 years now without any melting issues or anything else. I'm at just over 50w per chip on 133mm sinks. I've also been boldly exceeding the voltage ratings by running four chips in series, but I painted the connections underneath with liquid electrical tape to prevent arcing to the heatsink.

I can't remember if the screw pattern is the same or not. The other option is just to use some screws to mount the cob. You would need to solder the wires onto the cob directly but would save you trying to find another holder. It's been a while since I played around with those big cobs.

im not aware of any heatsinks drilled for the 058 holders that can be run that hot. the mechatronics i sell require bare chip mounting and soldering of chips. ive never seen a bjb used over 150W

I had my own custom heatsinks back when I was playing around with high powered COBs, they cost alot but worked really good, mechatronix didn't have anything good enough back when I was running cobs to 220W. I noticed the issue with a plastic holder when I went too far, my heatsink was fine but the holder couldn't handle it. I was making highbay lights for extreme conditions but also using the design for grow lights too.

I've seen Migro has already new CXM32 gen4's(youtube vid). Is gen4 already available or is he really the lucky one getting the first samples?

Migro.. the only guy in this industry that talk about ppfd per Watt while the most serious companies talk about µmol per watt? ^^
