Bridgelux Strips Driver Advice Needed

Cob vs Strips

I've made my own strip light before with bridgelux. I'm curious though what's the deal with cobs, I used to be interested in them until I found out how easy strips were but seems like folks still build cobs. What's the pros and cons between the two, how do they compare for those that have had both?

How many strips per driver you running on that light bro ?

2 strings of 4 strips per 150 driver, each at 700mA, but since theres 2 channels per strip it works out as 4 strings when you have both channels on at the same time. That should give approx 2.6-7ish ppf per w, 2.4 if only one spectrum activated. Refer to vesta test thread for the tests

Thanks those drivers for the Vestas got me confused this is the Vestas I'm gonna with 20 of them to almost the same amount of lumens as the slims actually more

Since it's made for the Vesta series the changeable cct or can I run a normal normal meanwell driver ? Or is there a driver or drivers you would recommend with this 20 strips ?

Where can I find the vesta test thread ?
I appreciate your knowledge truly

This means that when the channel current on each light strip is adjusted to 350mA, it provides a photosynthetic photon flux within the range of approximately 2.6 to 7 PPF/W, I would like to confirm if my understanding is correct?

Cheers to Vesta, bro! How large of a tent do you plan to use with 20 Vesta strips

Let me get back to you guys, but it would help to know what is the size on ur build SWS?

Theres info in the vesta test thread, it may be easeorr to find using google "vesta test rollitup", and also some info in "bridgelux gen3 rollitup"

I will be running the light in a 4x4 enclosure. The strips is 56cm so I'm thinking of putting 2 on a sink to make 112cm to get a better coverage

Bridgelux Vesta strips tuning?

Has anyone tuned their 27K - 5K Bridgelux strips & how do you tune your Vesta strips? I want to use BXEB-TL-2750G-3000-A-13 strips, but I want to be able to tune the strip to 4000K for a clone veg light. The only way I can find to do this is use the Bridgelux BXCS-1224B-N2A-01-A Bluetooth...

Lol all my questions answered by you thanks brother I appreciate it and thank you for sharing your knowledge

For gen 3 tests go check the other thread mentioned, id expect the 4k 80cri to be about 10% more efficient in ppf/photons than 2700k 90cri tested.

Thank you for your recommendation. It's a pity that purchasing GLA from Australia is difficult for me because I am not in Australia.
If there's an opportunity, I would try to purchase some



And this is additional information as a follow-up to my previous response

Thank you again

It was easy for me to get them here in the US. Shipping was expensive but they have discounts for overseas buyers. There is also a RIU discount code and significant discount for quantities over 1 or 2 strips.

Not to mention that most people see the price and think its USD when its the relatively light weight Ozzie-g'day-mate dollar.

We went for those fancy t-slot heat sinks which are very nice but a bit more pricey. But for bigger builds they can be sourced on Alis-blubber for discount (though i dislike the idea of shipping heatsinks that far due to price and general feasibility - and yeah that eco-climate thing aswell)
Also, for bigger orders id rec asking if they could send a pcb as drill guide. Just drilling straight thru the holes and hand fitting is a breeze in comparison with fitting/marking/drilling and then realizing the strip wont fit nice and snug. And drilling thru the actual strip of something with that thin but solid seal seems to be an invitation to Murphy. But i guess you can make a hole guide with some wood aswell.

Id rec them as our second fave light after our low k high cri lights.
And yeah you can turn them up pretty high, were running 8 on 320 driver and thats potent enough for some albino tops. but you could do 3x 200 driver with proper sinking and maybe a little airflow over them. Cant say enough good stuff about prawn and GLA, they hang over at icmag nowadays and do occasional discounts and will work hard to get both your business and full satisfaction. My only gripe would be that id like the strips in their more flower centric spectrum, the one of their boards.

This means that when the channel current on each light strip is adjusted to 350mA, it provides a photosynthetic photon flux within the range of approximately 2.6 to 7 PPF/W, I would like to confirm if my understanding is correct?

Estimated and at board level. And to 2.7 not 7 but assuming its a typo. And remember this would be at full power, drop down to 200w it would be 250mA per channel with both channels on. Now i cant remember if its 12 or 14 parallel strings per side but that means each diode is getting 20 or less mA, making reasonable assumptions on diode voltage. If something different then we would still be along those power levels in watts, about 0.06w per diode. Which is really really low.

Thank you for your response. I apologize for the mistake in my input; it should be 2.7.

I did a rough calculation, and if I use the same 250mA to drive the light strip each channel, then maybe I would need to purchase 25 Vesta strips. The total power calculated is 310W, which should be sufficient for my 3x3 tent.

0.25A× 24.8V =6.2watt （each channel）

6.2× 2=12.4watt （each Vesta strip）

12.4W*25=310W

Is this correct..？

Yeah but how would you lay out all those strips i cant see them fitting in or any good driver solutions. Remember im doing 4 strips in series, youd need to go down to 24 but then how would you lay that out in a sensible way with 6 string of 4?

Just check the pics if youve found them, where does your 25 strips fit in??

Id see more point in maybe going 12 vestas, maybe even in gen2 speced for 1 amp, 3 vestas gen3 about 60 V + 11 monos on a kb11 strip fromkingbrite: 11 diodes, say 3 uvs (12V total and 8 red xpgs for around 20V, the whole thing totals out to at around 90V for the basic string. Means you could almost put 2 of those string on a 200w driver. Or say a 200w driver for the perifery and a 150 for the centre to actually be able to use the extra power around the sides even at full power.
Maybe throw together another 10V of monos to get to 100 so you dont accidentally go over 1 amp and presto you got enough a 1m tent or running this light in open space.

Also going up in power, gen and amount of strips is going to raise price a bit, and you may do cheaper with a bought light. But youll never get that feeling of doing your own and having it light up for the first time, or see how youre beating records with your own design...
