I've had the HLG 550 for a couple weeks now and it seems to have taken the place of Bestva 1800 (foreign junk) and Mars II 700w without issue. i'm moving up in the LED world. I've still got advanced p300 and I'm looking to return it and spend that money on new, more efficient tech, particularly...

has anyone used these yet? HLG-480H-C1400A - 343 FV HLG-480H-C1750A - 272 FV HLG-480H-C2100A - 229 FV HLG-480H-C2800A - 171 FV They seem well suited for a 4x4 area. I have just picked up a few, but haven't wired them up yet. In the past I've noticed that meanwell drivers seem to kick out...

I got a Unit Farm ufo 80 led light. It has two switches, one for veg and one for bloom. It uses cree diodes. It has a mix of white and blue for veg and red for bloom. Any one that follows any of my threads knows I like full spectrum for my plants. This light should work great. Use the veg...

What's up everyone! It's that time again! The next round in the cabinet has begun and I'm happy to say I'll be running some Malibu Pie by Ocean Grown Seeds. I'm really looking forward to the terps in these! After 24hrs in a glass of water, and 24hrs in a paper towel, all 4 have popped nice...

Hi all!!! Does anyone have a good led bulb setup? Pics would be great. Working with 8 60watt led Cree bulbs. All have the bulb covers removed. The splitters we bought put the bulbs at pretty sharp angles. So just pictures or advice would be great. This is for germination / seedling stage...

What’s up RIU, I’ve been lurking in the LED forum for a little bit now, but I have learned most of my stuff from growmou5’s YouTube channel (Shout out. You’re one hella smart dude, my dude). I’m currently looking to build a COB system for a 4x4 grow space inside a 6x6 closet. I know this is a...

Hi, i am new to cob lighting i have been researching online and am getting ready to buy my first setup, i have only ever grown using 600 watt hps/mh lighting, i am looking to get a cob setup that can replace a 600 watt hps light, my space is limited so i only need to cover a 3x4 tent, how many...

Hi. I am interested in switching to a gowmau5 style cob setup and was checking out this Johnson cx-16 as an option. Is anybody using this setup? One retailer claims that they use Citizen clu048 and another claims they use cree cxa 2540. Does anyone know which cobs they use?...and which are...

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...

Okay, so I've done some research on the efficiency of water cooling vs forced air cooling and it seems to me that water cooling is the way to go. I understand active air cooling is usually effective but my decision to go water is based on two things, I already have a few high gph pumps and other...

I've run several successful grows in my small 60cmx60cm tent using four CBX3590 36v 3500K CD Bin COBs powered by a Meanwell HLG-185H-C1400B LED driver, actively cooled using PC heatsinks and fans. I've just been gifted the space to go up to a 1.2mx1.2m tent - thanks wife :hug: Will my current...

After extensive research, I finally feel ready to make this post. Here is what I want to do: I want to build a light for my small grow space. To begin with, I will use the same light for everything, and I want to be able to expand later. The light needs to be energy efficient, as electricity is...

Hello everyone, I have been waiting patiently for a couple months to see if the COB switch over had any other benefits other than the biggest, frostiest buds I've grown (Check my grow journal, in my sig) or no heat in the grow room and I wanted to contribute by showing an example of the amount...

Hello all, I recently built a COB light using Cree cxb 3070 3000k cobs. Specs: 3 x cxb3070 Meanwell HLG-185H-1400B heatsink currently passive cooling, but I will add a fan if I install a new cob As far as I understand, I can add another 36v cob to this setup. The light works well, but I'd...

Hey gang, how difficult would it be to swap out the chips on a light like : https://www.amazon.de/Roleadro-Pflanzenlampe-Vollspektrum-Gew%C3%A4chshaus-Wachstumslampe/dp/B01N0NQ6ZY/ref=sr_1_3?ie=UTF8&qid=1489491281&sr=8-3&keywords=roleadro to better quality chips? also what kind of chips...

Hi. Trying to get some sort a design together for my first LED build. I have a space of 1.2m X 3.6m to cover, or 4 feet by 12 feet for anyone working Imperial. I know tech is changing but I would like to stick to the Cree COB's as I know I can buy them in the UK with little or no hassle...

Hi RIU! About to take first steps with leds. Would like some assurance that everything is on point. Have been looking from RIU,Growmau5 videos to gather some knowledge to build my first very own light. I'm from Europe so it's hard to find good place with predrilled heatsinks, KingBrite name got...

Hey fellow potheads. I am seeking reliable knowledge regarding LED lighting. With Cree I know the CXB3590 chips are the best to go with due to Higher efficiency than cxa chips. as for vero and citizen i dont know much and any info and experience with them you can share will be appreciated. I...

INTRO Hi all. I'm a relatively inexperienced grower, but I'm a big LED nerd so when I discovered the COB CXB3690 threads here, I got really excited. I had been growing with hardware store CFLs, and was looking for a way to up my photons cheaply. I had been wanting to build a 10w array for...
