diy led

This is how I built an overpowered light worth $2500+ on the market for only $850. All currency is CAD. *BEFORE STARTING* Watch the 6 part growmau5 series to learn the wiring: For the grounding plug: Technical: 4x Hlg 185H 700ma in series drivers (i suggest you buy the newer 240H...

Has anyone tuned their 27K - 5K Bridgelux strips & how do you tune your Vesta strips? I want to use BXEB-TL-2750G-3000-A-13 strips, but I want to be able to tune the strip to 4000K for a clone veg light. The only way I can find to do this is use the Bridgelux BXCS-1224B-N2A-01-A Bluetooth...

I'm torn between doing a build with samsung F strips and the HLG QB132. At first I thought it would be cheaper to go with F strips, but the heatsinks are making that not the case. I'd get 48 more diodes with the F strip build but the QB v2 have the newer chips... Seems like it makes more sense...

I've been reading posts nonstop for days now. Trying to build my first set of grow lights for a 2'X4' space. First I was thinking cobs, then the HLG qb132 4 pack, and now I'm thinking of some samsung f series instead. The idea is to run 3 LT-FB24B in series using a HLG-320H-C2100. Does this seem...

I have 10 x Cree CXB3590s and 2 x Mean Well HLG-240H-C1750B drivers to drive them, with some CPU coolers for 6 of the lights, as well as 4 purpose-made passive heatsinks I bought with the COBs. I tested my components before I made a DIY frame for them to test if they worked, and all seemed...

hello, like the title says!! I would like to build a 400w LED that’s dimmable, preferably 4 separate COBS. What would be best to use and why?

Whats up my Led Brothers!!! Finally i got my first light togheter.....Got the aluminum L brackets for the frame, 4 Heatsinks, 4 CXM22's 90 CRI 3500K and a HLG 240H-48A Driver. I am completely new to the LED DIY lighting and need some help before i light this up! Before anything.....how do i...

I'm sorry if I posted this in the wrong area! I was originally going to go with a 600watt hid in a 2×4×7'11" setup. the company sent me all used and/or broken things. I've been battling back and forth for a refund for almost a month now. Well I got the refund about 20 minutes ago! I have...

First of all, apologies for a duplicate thread. I used the search function and looked for the past hour and I can't find (too stupid to recognize) an answer to my question. Any help or simply a link to something where I could find the answer would be GREATLY APPRECIATED. Also my body is ready if...

hey guys, pretty self explanatory here. Just picked myself up an HLG-600-54b from a gentleman with 6x 2700k and 2x 4000k qb288(the 561s), heatsinks, all hardware, fans, waterproof connectors, for $730 altogether. Solid deal I feel. Just built a 4x 2700k on two slates designed for 3 boards...

Hey guys, So, I'm pretty new to growing indoors and growing cannabis but I've always enjoyed gardening, so this whole new journey has been a lot of fun. Learning about indoor growing and lighting in particular has lead me to believe that there is a need for more suppliers for the DIY LED...

What's up everyone. So I'm now building a flower light for my tent. I did a veg light with 4 cree 3050s 6500k. Driven at 76.3 watts each. Each cob has its own driver. Running at roughly 44.5vdc I believe. Not 100% woukd have to check the actual voltage of the driver. The drivers ate specifically...

Hi everyone, thnx for this great forum, glad i finaly made a account. First of all, i apologize for my bad english. Im learing it all on my oun. I hope i dont get jugded on that. My passion for diy leds started a few months ago, after i bought my first led growlight. After using it i saw few...

This light build is for a small area, and I am using some inexpensive Cree CXA2520 and 2540 cobs. I must have gone through 10 sketches/schematics based on different cobs and current options for a small space (2x2 or 2x3). After jumping the gun and ordering some HSUSA heatsinks (2@ 21" x 5" and...

Alright so here we go first diy cob build... So im going to hook up 5 parallel strings of 2 parallel cobs each on a cpu heatsink+fan using a single power supply(36v 11A) 5step up buck converters(one on each string for the leds) and one step down to run the 10 fans. List of equipment 10 CXA2530...

When a driver says it's output Voltage is 107-215V as long as I use 108V of COBs it's not going to harm anything, right? I plan on running them in a series and couldn't find anything about if there's too many extra unused volts being supplied by the driver.

Anyone ever seen this (see picture) it started this morning. This is a ninja fruit. Not quite sure what's wrong with it. I am having low humidity 36%-40% and 80°-85° temps. Full hpa system. Veg bloom nutes with extra cal mag+ silica and enzymes. pH between 5.8 to 6.0, ec 1.7- 2.0 Citizen clu048...

I've been lurking for awhile and I figured it's about time I made a contribution. This is a legal medical grow. I'm already almost two weeks into flower. I have 2-600 watt diy led fixtures over 2- 4x4 scrogs. This is my 3rd grow and I'm pretty enthusiastic. Help me out folks :). I'm growing...

Finished up my new light and hung it up tonight. It consists of ten Samsung Acuity hard strips, 56 LEDs in double rows on 22" x 3/4" strip boards. I mounted two strips to a 48" long 3/4" aluminum U-channel, for a total of five light bars. Framed them together with 3/4 aluminum angle, for an 18"...

Hi Guys; I'm planing a Panel with 4 CLU048 COBs. My Box is 0,5 x 0,6 m and 70cm high. If I remove the Veg-chamber above the height is about 1,2m. I plan to put 2 Cobs each on 1 heatsink. Iam scared that it is not enough light everywhere with 4 Cobs??? I want round about 100W. I wanna run...
