Introducing LED boards that beat COBs

Hi guys,
I would like to introduce a new boards we are currently working on - LIGHT BOARD 320

These boards are made from 320pcs of SAMSUNG LM561C S6 chips with mixed color spectrum (3000k/4000k).

Some info you can find on our website :

Boasting efficacy approaching 200 lumens per watt at low power, these diodes are incredibly efficient. Typical forward voltage for each diode is ~2.7-2.8V at 65mA of current. Absolute maximum current is rated at 200mA per diode
Thermal managment is simple as fuck – light boards do not require active cooling and can be just mounted to a thin piece of aluminium
Greater efficiency. At 50 watts our lights are getting 180+ lumens per watt. Highly efficient COBs like the Cree CXB3590 average 160-170 lumens per watt at 50W or Bridelux Vero 29 S7 average 123-163lm/W

These lights aren´t really known in Europe yet but if you look to USA there is a lot of people who run lights with these chips and proved they works.

Here is how they should look like:

Is here anybody who have tried these led chips before? :slight_smile:
Is here anybody interested to try them out?

I am thinking of trading a plasma out with a LED at some point. Right now i stack a plasma with a 315 CMH. I worry about how cool they are during winter months but during summer it would be a blessing.

Im in the middle of ordering strips for a build woulsnt mind putting them next to my eb strips.

Maybe in the near future i will try them, for now i’m happy with my two COB rigs… Would like to learn more tho, can’t avoid change, and gotta go with the flow…

I think @Baudelaire experimented with some samples of Samsung LM561C chips:

This is the PROBLEM at 200 l/w you won’t be growing much.
Stick with the EB strips or professional grade builders like QB.

When you have HARD data on your project come back…

Yes I would be very interested in trying those out myself, Just can’t afford to right now with the hurricane that hit us here in florida money is tight due to cleanup… Looks similar to what Growmou5 built a few lights with on youtube, same chips I think i know they were samsung chips.

Yes , they use the same chips and it’s called a quantum boards from HLG

He is using the same chips as the Quantum board but looks like his has more chips per board than QB

Yep… same chips… that isn’t my concern… it’s the engineering ability.
Anyone can throw a bunch of chips on a board (just check RIU) and say
it beats whatever they want to compare it to ON PAPER.

Want to know what the l/w is at whatever current they use as standard,
the heat profile running at that level, etc. Then you run up against the
price point of such a board, limited run, setup costs, manufacture dates,
and issues unforeseen. Products not PreOrders…

He was using CREE XP-E epileds, was he not?

no he was using quantum boards.

But he had epileds around the quantum boards…

No, I don’t think he used epiled’s those are the cheaper LED’s made in Taiwan here is the parts list

These are not epileds?

I wouldn’t be surprised if all these boards are coming from the same factory in China as the QBs.

What doesnt come from china?XD

No they are not epileds. they are Cree, Epiled’s are a manufacture from Taiwan and Cree are made in the USA
