dimming

I'm in the process of looking at indoor equipment and live in a country where electricity is not exactly cheap. I was wondering if I'd be better off buying a LED growlight that is higher wattage, slightly more efficient (higher quality bar setup) and pay a higher price for it up front if it...

I wanted a way to control dimming on multiple MeanWell drivers without using optocouplers and resistors. I created this github page with all of the details to share for anyone else who's interested in doing the same. Feel free to post issues or discussions on the github page if you're interested...

Hello, I have an indoor frost pro 280W in a 4x2 tent... I am wondering about light dimming and the height of the light for the plants... If I am starting a grow with seedlings what height should my light be at and also how dim should the light be? How do I increase the light over time on the...

Hello, I suspect my current potentiometer is a bit dodgy so I want to replace with a more expensive one - I currently have a 100K ohm pot, are there any other specs I need to check? thanks

So for The light I am building I would like to use a controller, which leads me into using the LDD Drivers so things are able to be controlled.. What I’m not understanding is 1) Say I chose an AC/DC power source that has an output of 36 Volts, and I want to control 5 different strings of LEDS...

I bought several units of these panels from their website because I found them to be the most similar of what I would expect from a cob led lamp. They say this panels use: CXB3070 AD bin HLG-120H-C1400B APV-8-12 Dual Bearing fans on a proper heatsink so fuck hell, I avoided a lot of job. I...

So I bought some cxb 3590's, pin heatsinks' driver, the whole 9. My question is, does anyone have a tutorial on a pwm controller? I'm interested in adding different channels to my cob light and I want to be able to program when certain diodes and cobs come on and off or dim.

Hello to everybody, i'm going to buy a MeanWell HLG-320H-C1400 to drive 5 CLU 048. I'd like to buy the B version instead the A because i think the internal screw is not so practical in current use. Could somebody help me to find the right Potentiometer to buy (1-10 V? 0-10V) maybe linking me...

As promised, a fairly detailed 'how to' vid showing thermistor applications with dimming rail on dim-able CC drivers; plenty of stumblefuckery and bad mental arithmetic, standard form fer my shabby productions!

I have two 36" heatsinks and 4 Cree cxb3590 for each. I tried hooking my light up with my B version meanwell 185w, and thought it should all be connected right, well i never could get it to work so some wiring must be wrong. I'm asking for some help on wiring since I apparently forgot some...

Hi, im running these with dimming option from HLG320 1400ma driver, CB binning How can I know how high to turn up the dimmer without causing deterimental effects to my plants? the plants are in 2.5 x 2.5 space thank you

I'm planning on building a 9 cob display using citizens clu048 and 3 HLG-185H-C1050b drivers. I've got some dimming questions for you LED fanatics. 1) Will these drivers make any kind of electronic noises? 2) Will dimming these drivers make my drivers make some kind of noise? ^I'll be...

Hey you guys, I know, this is a subject reheated over and over again, I have searched many diufferent threads and forums, but failed to answer all my doubts. I have a SJ DR60 tent which is 2x2 and little shy of 6 ft high, which is quite tight. There will be some ducted ventilation in it going...

Lets assume over 4sq ft: Setup A: (4) cxb3590 36v 3500k CD on (1) HLG-185h-c1400B dimmed to 50% Setup B: (4) cxb3590 36v 3500k CD on (1) HLG-80h-c700B at 100% power 1. These setups pull approx the same wattage amount from the wall, correct? 2. Is Setup A just as efficient as Setup B...
