Vero vs Citizen

My concern is pretty narrow, specifically the BXRE-30E6500-C-73 at 500mA to 1050mA and it looks good in that range.
If I wanted 55W-80W per chip the BXRC-30E10K0-C-73 would seem to rule. Or similar to others in its league.
The datasheets show a lot of variance between binnings. The DIY testing seems to show most chips in the same LES/voltage class performing similarly, although there seems to be 5%- 10% of variability depending on conditions and I have no idea what controls are in place. I'm not aware of any rigorous industry-standard way to judge the real performance of these chips relative to one another in any detail. We have these tests and calculators but how accurate are they. It kinda goes back to what appears roughly good enough for the price depending on what you can afford. Bridgelux at least provide helpful datasheets to give what I hope would be a pretty close approximation of their real performance. It's easy enough for me to understand.

So do you guys still stick with your original statements from a year ago! I know led are making a lot of noise in the last year!!! What's the best for best price!

usually year-old data is pretty much obsolete in this industry. That said cob manufacturers havent come out with new gens since this thread (most are on 16-20 month cycles)

i think luminus is the best bang for the buck followed by vero and citizen

cree is a distant also-ran

Where is the next Luminus generation on cxm22 ?

Is this a good system for a 4x4 tent area to replace a hps 600w. Any help be great as can't make my mind up between cree, vero or citizen lol

Citizen CLU058 1825 grow light with 4 COBs mounted on a Cooliance heatsink. Size: 80 by 80 by 20cm Weight: 10.5 kg

Power Supply: Meanwell 2 x HLG-240H-C2100. This supply provides an onboard dimming function. Total LED Power: 480 Watts (560 Watts from wall socket) Total light output: 4 x 18,321 = 73,284 lumens PAR Readings (measured directly below the COB):

Anyone?

It will work ok but ideally you would want more cobs spread out to cover a 4x4. You can get away with 4 cobs for a 3x3 but for a 4x4 I would definitely get more light sources happening - at least 6 or even better 8.

OK thanks buddy, are the 058 citizens as good as vero 29 and cree, in your opinion or all about same

In my personal opinion I prefer the Veros. Specifically the Vero 29 C.
can you share why they are better in your opinion?

in terms of flux per watt the vero Cs are in between the clu058 and the cree cxb 3590. But thats only one factor in chip selection. vero Cs are essentially identical to citi gen5 1825s at all wattages, but they do have the built in holders and conenctors and such

Ease of use (SE), availability, sheer weight of documented grows, I like Bridgelux as a company etc etc. I am sure the Citizens are fine but he asked me my opinion and I prefer the Veros. If I was going to build another light right now, I would use strips but for COBs the Veros are king imo.

Thanks guys all good info and I am very much in ur debt for ur experience and opinions
Klx, I seen the boards but not sure where or what types to get here in the UK, think its Samsung off the top of me head lol
