Décor Food Vero 29
BXRC-17E10K0-C-74
FWHM of the red part would be ~107 nm
Cree's 3000K/80CRI for comparison
According to Bridgelux tool @700mA and T_c = 50 °C: 45.3W, ~50 % efficient and 2.625 µmol/J
e: They're unfortunately m̶o̶r̶e̶ ̶e̶x̶p̶e̶n̶s̶i̶v̶e̶ ̶t̶h̶a̶n̶ ̶r̶e̶g̶u̶l̶a̶r̶ ̶V̶e̶r̶o̶s̶ (the price I was looking at was in CAD) and not in stock anywhere but I want some.

Damn those Vero 29-C kicks some ass at 1050 , 10 of them and you can replace a DE Gavita Boosted.
Do the Vero 29 comes with a build in holder ? Ore what

I like these chips aswell but maybe more the B version so you could get it on paralell connections on hlgXXX 48A. My idea of using these is to have a few 3500s or 4000k on a bar, and then maybea couple of decor reds and couple of 5000+K on the same bar connected to the same driver, but with some basic light switches so you can bring in extra red or extra blue whenever you want without having to mess about with another specialized fixture.
Full spectrum + ability to bring in more red or blue as needed. Would be kinda cool. Would add a bit of cost to each fixture but less than having to build 2 more lights.
Does anyone see a problem with this approach? Other than paralell? As me still quite a noob...
Edit also big thanx to alesh for working out ler and qer

Youre in the eu, right? Me in spainyeah i would like to have some too
These guys have them on their web but only for MOQ : 50 if i understand them right. I would definently pick sone up if anyone would go in for a groupbuy
Also soselectric is in eu

I'm not really sure how well different CCT/CRI COBs do in parallel connection. Might be that 5000K runs cooler and has slightly higher Vf. I can't neither confirm that various versions have exactly same Vf.
I'm in EU as well and I could use 5 pcs too if there was some kind of group buy. Do SOS carry Bridgelux products? I can't find any.

Sorry i forgot to post the link. They seem to carry bridgelux but they say on order:
https://www.soselectronic.com/search/products?query=bxrc-17
Searching for bxrc bring up the whole catalog. Im short for cash to organize a group buy but im in for 6 if someone pulls the trigger. 5+5 + 6 +20 = 36, almost there for 50 but not to sure on their stock, has been saying 5-10 days for at least 5 days now.
As for paralell diffrent cct: i think the cobs of same cct might already have slightly diffrent Vf from one cob to another so im ready to take that risk. Its to cool not to try. My pro-grow mate keeps refering to this idea as "holywood".
Which basicly means almost anything which isnt hps 600...
@Malocan would like to see one of those chips under your fancy light meter for sure

Oh I see. I couldn't find Bridgelux as a mfg on their site. They call it just BRI. I certainly want the C version though.
It needs to be tested. I just threw it in as a possibility.

Id probably pick up some Cs anyway if thats whats going. Another thing, anyone used the molex connectors with a high voltage driver? Would like to try with a pairui 1400ma (189 v) but the molex rating is for 130v. Has anyone tried without burning down the house? Im a bit nooby with the practicals of electric. Also, running them at half the rated amps (max 2.8 should give yOu a little extra margin on voltage? Anyone actually tried?

i did build some days ago a lamp with 3 pcs vero29c and hlg-240c-1050, i used molex connector to connect them in series.
i tested my lamp for 9hours++, all worked fine. But after robincnn mentioned that the molex connector is only rated for 130v, i did rebuild my lamp and use solder iron to connect chips. i prefer to stay on safe side

Ok, nice to know. Will build them with molex for the first trying out phase and then solder when final config is decided.i did build some days ago a lamp with 3 pcs vero29c and hlg-240c-1050, i used molex connector to connect them in series.

not sure what your set up is;
the max voltage the molex connectors see is the Vf for the cob, not the sum of all the Vf.... isnt it?

On the other hand, why would there be a high voltage version of the holder (e: or connector) then? No compatible COB needs more than 130 V.
There certainly will be a higher voltage between the first COB in series and ie heat sink.
