Would you consider buying a VERO after reading through some of the posts?

The one that ends in 04 is an older model so the one ending in 24 is the one you want out of the two.

It's very interesting how the older one heats up a lot less and it also is more lumens at test current. Why choose the new one. Am I missing something?

your comparing lumens at two different test temperatures. 85C vs 25C. invalid comparison. open up the datasheet for more data.

I'll be pulling in some Vero 29s shortly, having snagged a great deal on 20 new Mean Well PSs off Ebay

Qty 20 HLG-185H-48A, $18 each delivered!

They won't do a high enough voltage for my other favorite COBs, I think I'll mix the 3000k CRI 93 with the 4000k CRI 90 Veros. I should be able to do a whole 320w fixture for about $120, IP56 washdown ready too.

does anyone know when the new veros arrive yet?
i want to build another light but i mean wtf this new veros are completly like the cxb 3590 :p

Apparently there are datasheets out there but according to Bridgelux they haven't been released yet.

Nice find. D version is what we're used to and there is a 95 and 120w vero 29 along with a 48w Vero 18 among others.

Not sure the 18B and D data is correct, notice the flux doesn't seem to be calculated properly for the parameters given.

LPW is a nice improvement over v6 but likely still at 25C readings so the 3000K will be more like 150 LPW at typical temps and 3500K around 155 LPW. The fact that there are three versions is interesting but still not a lot of information to draw any conclusions without pricing and performance curves, but if the previous version is similar in scale then we might see 29D hitting 170-175 LPW at 1.05 amps. Not exactly a CXB killer, but there might be a curve ball in there still.

The new Mean Well ELG-150-C2100* looks like it might be ideal for the current crop of Vero 29s, limiting them to a safe/conservative 150w and self adjusting in the range of 36-72 Vf. Jameco lists them for $0.23/watt, although NOT is stock. The new (and currently hard to find) Mean Well ELG-150-42/48/54** would also work great and will likely be even cheaper!

I was hoping to pop the latest vero29s into my year old optic and use the same meanwell drivers. Its lights out and I dont recall the exact model but there are 4 drivers driving 4 cobs at 2.1mA. Can anyone determine if this is a worthwhile swap? I cant figure out how to interpret those data above.

Basic guess is that replacing the v6 with v7 38V type will provide about 4500 more lumens from a 4 cob lamp at 2.1 amps. Not sure if that's going to make it worth it to upgrade from v6 to v7, but if anyone is still rocking v5 and want's an easy upgrade it might make sense.

A few more observations on the new Vero...

Going to have to start looking around for good driver combinations for the new 95 and 120w Veros. HLG-240 at 1.75 might pair well with 2 120w Veros at nominal... frustrating puzzle though. 3 wattages all with the same LPW at test current and same package size. And if package size is the same will the pricing change based on type or be similar? Who would buy the 80w Vero when they can get a 120w for the same price? If they were only playing around with the parallel strings and input voltage then one would expect some performance drop for the higher wattage type at the same test temp... unless the diodes are not the same or some other type C specific process. Thinking along these lines might indicate a price premium for type C.

If that's the case I'm going to be very curious about what 29C can do at 50 watts and 75, and what the price is. Taking a look at some HLG datasheets for compatibility... very interesting ;)

Thanks for your thoughts. I am rocking the v1 iteration.

Ill be interested to review the data sheets when they become available.

UPDATE: The drivers I'm hoping to re-purpose are meanwell lpf 9042

does cree care and release also a new generation of cobs in the near future¿?
sounds really interesting - thank you for sharing the information like always ;-)

Once they've gotten things to a high enough binning, they'll probably jump to (I guess) the CXC Family of XLAMP COBs.
