I have read many posts on the subject of the, all around the internet you could easily get lost or lose interest… There are so many conflicting posts …… Here is a ex.. you will need 8,9,10,14,16,18 strips which one is right
These are the boards I will be using BXEB-L1120Z-35E4000-C-B3
Thanks in advance to all who read this and reply……….
  • How many EB Series Gen 2 strips will I need to cover a 4x4 area (a room)
  • What size driver(s) will I need
  • Where to purchase Strips and Drivers (without a tariff fee would be great)
  • Spacing of each strip

1 depends on how hard you drive them. At fairly standard 1050mA/40w each youd need about 12
2 id rec 2x240w drivers for around 30w per square foot.
3 Locally: go to blux website and check where to buy section. Sorry but theres a bit of a doh factor here. You havent actually given your location so how can anybody figure this out but you?
4: those maths are so simple you shouldnt be building if you cant figure out spacing from info above.

Happy building.

How many strips you will need of 1120mm BXEB Gen2 is directly related to which driver you select, and the current level provided to each strip. The level of current you provide to said emitter, will determine the type of thermal management hardware, if any, you will need.
This is why you are finding "conflicting" responses, they may all be correct in their own way....

Start with the square footage of the area. 16sq feet. I happen to have vast experience with BXEB emitters. That said, I will recommend a low end of, 30W of power consumption per square foot for BXEB 3500K. So in one fashion or another, you will want 480W of power being consumed by these strips. Whether that is a single driver, or multiple smaller drivers, is up to you to decide!
Let's look at an example with a single driver. Since the BXEB 1120mm Gen2 is a 40V(ish) emitter, we'll look at the HLG-480H-42A driver. This driver has a maximum of 11.4A at 42V. So on paper, if one were to wire 12x 1120mm BXEB onto said driver, in a parallel circuit, each strip would receive just under 1000ma, and provide a total wattage consumption of nearly 480W(ish).
Based on experience, I know BXEB Gen2 can run at these levels without any heatsink, yet some sort of aluminum framing will be necessary for physical integrity. I recommend basic, 1/16th angle aluminum, or U Chanel, attached to each strip with thermal tape.

Know the voltage required for the chosen emitter. Learn the "sweet spot" current level for the emitter. Match the emitter to a driver of the correct wattage capability that also provides that voltage range. Calculate the number of strips it will require, to divide the total current available into the desired range!

Dammit Rocket I can't type any faster....

Edit: and since I got a niiiicceee buzz going, I can blather on about BXEB all night...
The old lady just rolls her eyes.

Yes, but the A versions are even better IMO. That's what I would do. 6x1120mm on each to get them running just under 1000ma.
With the A versions, there are built in V and A pots...

Using the actual part numbers, punch a search into the almighty Octopart search engine. That should give you all available retailers of anything you're looking for....

Glad to help, that's how I got to where I am.

30-35 watts per square foot. Some Meanwell driver size options are 480, 600, or two 320's. Mouser and Arrow Electronics have good prices.
12-18 strips would be common, I'd go with 14 or 16. More strips is more efficient. They can run up to about 1 amp/40 watts with no heat sink whatsoever and simple aluminum angle would be more than enough. Lots of Bridgelux builds here, do a search.

I did get a little confuse there are many 240 drivers i did not know what to choose .... what about the c2100

The C2100 you are seeing is a Constant Current model. That type will deliver a constant amperage, instead of a constant voltage. Those types will require series wiring circuits. Unless you get into even more complicated series/parallel adaptations.... Skip that for now.

In your case, a 2100ma constant current will not be suitable for your chosen strips, as the BXEB max current is 1400ma.

It might be hard to find in that voltage its not a common one. Led-tech.de usually carries that voltage though.

Also: for a tent build: to hang and raise and lower you will need to think clever or have access to 2 opposite sides. And
- if you want to save slightly on heatsinks you can mount the strips 2 wide on alu u-channel. I used 3 mm/ 1/8" which worked fine but 2 would probably work aswell. 3M brand self adhesive is good for sticking the strips to the sinks, check the actual ddatashhet for form factor before planning on screwing them to place, i think theres no real holes, only notches.
