Citizen CLU058 6x CoB Build

[Sup Im BirDy]

hey everyone new here and am a fellow DIY’er and I’m trying to tackle the cob build. I’d like a second opinion on my specs and would like to know if I’m right here.

6x CLU058 1825 cri 80 5000k COBS (VEG ONLY)
6x 12volt Mechatronics ICELED Ultra active heat sinks
6x BJB Holders for CLU058

And for the driver I was thinking either...

HLG-240h-c700b or the HLG-320-c700b.

Also I wasn’t sure if I should get 2 drivers and pair them 3 on 1 and 3 on the other..

I wasn’t sure if I did the everything out right because the added 12volts from the mechatronics heat sinks but she’s some knowledge on a brother

Everything’s still up in the air though. I’ve been looking into the CXM 32 gen 4’s also but tell me what you think. If there are other recommendations I’m very open to them.

Most people around here rec 4000k for veg. Some strains, especially indicas get too little node distance with 5000k. How much space are you hoping to cover?

Also, if your only driving these at 35ish watts then you dont need active heatsinks, and could probably do it cheaper using amaller chips. 1825: no point unless your over 50-60w

4x4 veg tent , I’m hoping to run them as you said at 50-60w. I was going to get 133mm passive pin heat sinks but I thought why not get the active ones for 2 dollars more. But I just need to know the right driver for the job. Also thanks on the tip with the node spacing! I was thinking 3000k or 3500k now just as a happy medium

those mechas dont take holders

youll need to mount the chips directly and solder to them

i agree at all this. in fact i personally wouldnt use 1825s unless i was 100-150W or more. luminus cxm22 on passives are just as efficient below 75W and almost as efficient in the 100-150W range

Well I wanna use them to their full potential, apparently I must’ve misread or over looked something in my specs gathering. Any recommendations. In reality I wanted to make a 400 or 600watt array depending on parts cost. I wanted to use the 1825s 3500k for this.

If you guys are busy please forward me a thread with the formulas to pick your drivers correctly and I’ll do it really appreciate the fast responses guys

This is probably the best guy to talk with.

I’ve noticed! Every cob thread has a post from Cobkits with some knowledgeable feedback

Cobby done a lot of good for the community, if youre in the US hes probably your best bet, excellent service, good advice and has all tge growrelevant cobs/chips etc. I got my first leds from him.

well thats a bit of a red herring, im assuming you mean max capacity when you say full potential, but chips are dramatically more efficient at lower currents as you probably know

unless youre somebody who needs 150-600W out of a chip or agiven application id stay in the 22mm LES size, in which luminus is the most efficient and cost effective
