Testing Bridgelux Vero 10 2000k w/ Samsung 3500k

Hi All,
*First off, I do not work or am affiliated with any Lighting company, what I built was purely for a hobby and have no intention of selling anything so Please do not ask. I will disclose where I sourced my parts if any are curious. Inspiration of this came from the Dawg using those 1750k meat chips.

Secondly I am open to any criticism or advice or help, thanks in advance.

Cobs came from Digi Key, they are the D version vero 10 2000k
Strips came from Alibaba just a samsung lm561c strip with 96 diodes.
Drivers came from Mousser
Metal came from local metal supply,
rest of stuff came from local electronics store and home depot, lowes.

Here's a quick cost breakdown of total light
strips = 60 Cad
Veros = 41 Cad
Drivers
hlg-120h-c1400b = 61$ Cad
elg-75-350a = 40$ Cad
Heatsinks = 35$ Cad(just 1.5",1.25" 1/8" aluminum u channel).
Artic silver Thermal Paste = 20$ Cad
Screws and bits and crap = 20$
All in around 270$ Cad to build and thats with shipping and duties etc.
* I do use 2 Panasonic Panaflo 24v Fans for running at 100% to provide effective cooling
* This cost an additional 10 bucks.

I ordered some Vero 10 2000ks because I was looking to supplement my 3500k samsung lm561 diodes. I wanted something low power and am blown away by these little guys.
They are 6 diodes being run at 350 ma each, running around 9 watts each for a total of 54w.
The Samsung's are being driven at 1400ma which is about 116.6667 ma per diode. 8s12p 96 total per strip, 400mm x 30mm.
All 4 cranked to 100% which reads about 130w. Both channels on full reads just over 180w.

I wanted to make a single fixture that could handle both veg and flower, I chose 3500k because it was a good mix but felt it was lacking alot. The samsungs are connected to a dimmer so I can dim them down to adjust it to make it heavier towards the 2000k spectrum as I need.

First is both.


2nd is just 3500k


3rd is just 2000k




As I mentioned, I am blown away by how bright and powerful these little cobs are. They are fantastic for supplementing if you want a boost for flower. I highly recommend this if your looking to supplement your lighting.

That is an excellent diy. Great small space grow. Love it when you get inspired by others and find your own path.

Thats great looking setup. Dual white(ish) spectrum FTW.

The 2000k veros look nice but i cant find much info on them. Do you have a datasheet, spectrum etc? If they are anything like the 2200k citi 1212 the spectrum is basicly just a huge bump peaking around 600 nm, with a little 450nm nipple. Havent seen anyone grow with this ever, nor bloom nor vegg. Both would be interesting to see.
They would probably grow a bit different to the meatchips; the 1750k peaks around 635-640 and have alot more farred. If i understand correctly these leds are made to replace HPS with leds while maintaing yellowish colour. Please post your grow. And happy growing

Your dead on with your assessment. There is very little info about these which is partly why I wanted to try them. I was able to find one graph of the spectrum and still no replies from bridgelux directly. I edited this from their pdf of info, its the only way I was able to break it down to understand the spectrum. Its peak is around 605-610nm with most of its spectrum falling between the 560nm to 655nm. By no means will this be a substitute for a flower light but wanted to experiment with adding some more orange and red without using mono leds, I find the veros give a great color mixing. and the mix of the two is alot closer to a hps spectrum so time will tell. The nice thing is they were only 4 bucks each and running at 350 ma they are a whopping 8.9w each while delivering around 1000 lumens so its only being used for color mixing. If the spectrum doesn't make much notice after a few grows I may swap them out for a 2700k or 3000k to get some more deep red. The chips are BXRC-20B1001-D-73.

Yeah, that spectrum looks more or less the same as the citizen mentioned above. Its cool to see someone trying something new, most people just talk about it and then nothing. But i could probably include myself in that group as well
Please post your grow, and if youre really into trying something new, try vegging a few days with those veros, see what it does. Most people say vegg with blue, flower with red but if understand correctly this just boils down to dont flower with HPS as the infrared will make your plant real stretchy but these veros have almost 0 infrared. It would give some info, and if you start seeing things going haywire you can always change back to samsung. But atleast youll have some new data.

Yes I will build a grow thread in the other section. I like your thoughts on vegging with the Vero as well. I'll turn them on and see how the lil seedling likes it.
