...All Things Vero...

[bobbuck]

Thanks. I'll take a look at the data sheets

Everyone is headed to 3000. No indication yet on whether 80 or 90 is better, but reports of 3000 -vs- 3500 are either neutral or favoring 3000.

does anyone have any 3500k, dont seem to be stocked anywhere in the high flux bins?

Well, datasheets can help you find the potential PPF (4000K will have the highest) but it won't tell you how the plant will react to the spectrum. The Mcree study suggests the orange/red band is 150-200% more effective in provoking photosynthesis than blue/yellow so a spectrum with more red should be superior, and yet due to phosphor loss there ends up being less light.

The only way to get to the bottom of this is by growing. That's why I've been keeping my eye out for any reports and so far 3000K is either as good or better than 3500K, which suggests it's better than 4000K as well. But I don't think there's been enough work done to state something like that conclusively.

Digikey may have some. They have a small selection but there's so many versions I don't blame them. My ETA for bulk purchase was 8-12 weeks when I ordered.

There are 30 different versions of the Vero 29, not including the decor/specialty types. So with all 4 size Veros, 120 versions plus the specialty spectrums, probably close to 200 choices.

yes dont wanna chose the wrong stock

My V22's arrived today. Does anyone here understand Bridgelux's binning setup? For instance BXRE-30E6500-C-73 is the model I ordered. I understand the last two digists to be that it's the latest Gen7 and binned to '3'. However, I don't know if the scale is a higher number being a better bin or what. I don't see it stated in their literature. Just that it's the bin number. Any ideas? I'm asking as the V22 specs states there are only two binning option, bin3-4. The specs on my chips state they're all Bin2. Which their literature states shouldn't exist and DigiKey, the seller states Bin3 on their website, packaging, and invoice. Something seems fishy.



Side note: I just hopped on Bridgelux's website. Looks like they just released the VERO SE line? Appears to be the Vero with built in push in wire retainers. (No need to buy their JST style connector) I kinda like that setup.

The 3 is a color bin indicating how accurate the K value is. You can see the color steps in charts further down the datasheet. Can be useful for consistency in consumer lighting but not something that will have much effect if any on plants. Just get whatever is cheapest or available.

That's very good news! Thanks for pointing it out. I hope the current reflector holder from Ledil will work with them.

Thanks for the info Rahz, I'm still curious how my chips are a '2', when digikey only sells 3/4.... and bridgelux only states 3/4 is an option. However, if this is based on the color ellipse steps I think you're mentioning, then the lower the number, the better? So 2 step is better than 3 step, etc.

 

[welight]

Looks like the Ledil Clamp will sit on it but becomes a holder on a holder and will likely block the wire release pins, I assume Ledil will release another holder to suit

2 step should be the most accurate. Digikey does catalog the 2 step bins if you look for them, none listed in stock though. 2700-4000 come in 2 or 3 step and the higher K come in 4 step only. Where did you get those?

I noticed there are only two 3m holes. As far as the clamp, it looks like the current design will leave the entry holes available but definitely will block the release mechanism... not something I would feel the need to wait around to be revised

The datasheet doesn't seem to indicate what gauge the entry holes will accept.

These were all from DigiKey. $13-16/piece. I bought 4x3K and 2x4K chips for my first decent light build. If the simulator specs hold true, these are almost as good as a ~70v Vero29, but 50% the cost(it beats out the 50v Vero29 by ~10lm/w when underdriven). I've only been able to source these from digikey. The downside is that I haven't found much for chip holders/reflectors. I have no issues with soldering these, but i was interested in adding a reflector down the road.

thats cool but doesnt look like there is any provision for reflectors

also it says

Ability to configure multiple arrays in series and
parallel reduces customer driver cost

and later

This product has been designed and manufactured per IEC 62031:2014. This product has passed dielectric withstand voltage testing at 1160 V. The
working voltage designated for the insulation is 80V d.c. The maximum allowable voltage across the array must be determined in the end product
application.

would be a good question for them as to whether its cool to run upwards of the 428V a HLG-320H-C700 can push (or the presumable 600+V the new 480s would push if they offer them in 700 mA constant current)

i wouldnt trust those numbers, both the vero29C and the V22-C have impossibly high low current numbers. the Vero29C didnt test out as expected, i wouldnt expect the V22C to either

 

[Trippyness]

Just picked up a bunch of Vero29 Gen 7 3000k.
Will test them out with a build and grow as well as a side by side.
Digikey has them in top bins.
Not many though.

Hey guys,
I would really like to join the group of people from EU which want buy in bulk due to mqq, I would like to buy about 10 vero v7s 3000k and 5 vero 5000k. Please what would be best possible way to drive them for high efficiency.
Which would be the best option for me C version ?
I got interested in this since I found supra, that was in 2014, back when he used cxas. Im really happy how these the evolution in led is moving forward .
Thx for the advice

Run them as low as possible but = 50w/sqf or 900+ PPFD.
Not familiar with the V series personally so cannot comment.
As for bulk those are quite low for bulk even with a bunch of people.

Hey Trippyness and everybody else,
I wanted to buy veros from china but now when it comes to bin, Im unsure which is the best (the c version) also which is the most efficient (36v or 72v ? and have availible good priced drivers in EU?
KB previously recommended that I should use

• 3x hlg/185h/c1050 ( I would preffer the b version if it is that one where you can attach the potenciometer) for running 15 vero v7 cobs - 5cobs each driver running at 40ww ( I have no idea which bin the KB have)
  
• I dont know if its a good driver for my setup, I dont want to overdrive the drivers or harm the cobs by doing that .
• 
  Please Malocan, Rcoket Soul, optzulu, CobKits, I know its been a few days when you talekd about group buy.I would gladly enjoy the group and buy 15 pieces /10x 3000k 5x 5000k if possible.
  
• Alesh please where did you get your drivers?

I would really appreciate the advice and help and finally It would be possible forr me to fully join an contribute to community

If your not going to group buy, buy from your country or youll get hit with big duty fees.
just got hit with $200 worth myself.
36v version is what you want.
I run mine at 2.1A with 6 in a 3 x 3 for 950+ PPFD
You could run more COBS and less current such as 1.4A or 1.05A, but youll need to invest in more COBS. Most important is uniformity, ppfd and efficiency in my opinion. Efficiency is important , but I think people make it a number one when its further down the line for most of us.

If you get a killer deal it may be worth it to buy overseas otherwise id stick to local country to avoid heavy duty and tax on import.

 

[CobKits]

in the US at least the 50V is same price as 36V and much higher efficiency
