driver

I hate to make a new thread about drivers, but I find conflicting or older information when searching about thermal runaway and I'm sure it could help a lot of new users too (or at least me). Can you help me settle the advantages and disadvantages of low voltage (parallel) vs high voltage...

Can anyone give me a heads up on adding a dimmer switch and power switch?

Like the title says I need help with these cobs that I am wiring. I thought I got everything wired up correctly but when I went and plugged it all in, Nothing. This is what I'm working with... HLG-320H-C1400B Driver 6- CXB3590 COB 36v- 3500K sets with thermal tape SST140 Passive Heatsinks...

I live in the Country and sure enough every fucking night some prick is tailgating me with his brights up. Usually I slow from 50 ish down to about 20 and theyll get the hint and pass me. One guy tonite followed me all the way down my street with his high beams on. I paused in the middle of the...

Hi, sorry for a dumb question but I have read so much and only get more and more cunfused so again I am sorry about it must have to ask myself for direct answer to my question. Found Kingbrite on Alibaba that so many talked about and got these bins for the CXB3070 that I entend to combine with...

Hey guys before I do my first diy Cob setup I have a question. What's the most important specs to look for when buying cob leds and drivers? Wattage + 3500k, warm white on the led and wattage on the driver? Here is the specs of the combo they are selling in a city near me. Cree brand...

Hello, good sirs. I'm planning to build LED-lamp for micro growing. I've decided to use 2 CXB3070, but can't choose which driver to use. Is HLG-80h-c700 okay? Maybe other driver? Thank you in advance.

Hi all. Thanks ahead of time for your feedback. I have an older led fixture with 16 cobs (some of which have failed) and I want to replace them with Cree CXBs. The drivers aren't a great match for Crees as far as I know... they are 550 mA constant current and voltage says 55 - 70v. What...

Driver specs: model: PT1004F-60W (60W) in: 100-240V out: 55-100V (0.69-0.72A) Can I run three CREE CXA2540 on one driver? I am still not understanding how this works. So 3x36V COBs like the CXA2540 (I mention the CXA2540 because I can get those VERY cheap) = 108V - but [email protected] = 75.6W. So...

I noticed today a couple Hewitt Packard printer power supplies that read 32v output and I am wondering if it would be a good idea to run Cree COBs with it. Would buying meanwell drivers be worth it if I already have these? Can someone help me understand the downfall to using these compared to...
