Preferred LEDs

Depends on what you're doing and what colors you need. Phillips Lumileds and Bridgelux are the most commonly used of late.

If I were hypothetically looking to make a custom multichip array, what would be the best high cri neutral white smd emitter?

Luxeon T or Luxeon M.

 

Maybe some of the Osram emitters but honestly I'm not sure which Osram are the best or newest. Osram datasheets give me a headache from all the languages running together.

If you're looking to do a multichip, then Bridgelux are out because they only make arrays, no individual white chips. You could do something like someone did on here and make a PCB that fits around a Vero chip.

 

What size tank are you planning this to go over? Depending on the height, you won't need a lot of LEDs on each one or to run them at high currents. I'm not a fan of using small PCB with lots of LEDs on them like most multichips as it is way too shadow-heavy for me, I'd prefer a bunch of smaller arrays that are all identical and have loads of them spread out across the tank. It takes a more involved heatsink design and takes a much larger footprint, but thats the tradeoff :)

Hmm. I hadn't considered that it would cause harsher shadows, which I guess thinking about it does make sense. Its for a small 20 long, but was planning to overkill it for future compatibility and so it could be underdriven. Preliminary design called for 2 clusters of:

 

3 Luxeon M RB

6 Neutral white of something

2 Rebel ES Lime

2 Rebel Blue

1 Rebel Cyan

1 Rebel Red

And some number of some violet

 

 

But yeah, I saw that bridgelux was exclusively COBs as far as I could find. Was considering the high cri bin nichia 219, but couldn't find the damn things anywhere.

Yep, look at tanks lit by Kessils, very harsh shadowing that really looks bad without supplementation IMHO.

 

Your current plan is extreme overkill to the point where it really doesn't make sense. Each Luxeon M is four Luxeon T in one package. You will have almost as many of the M that I had over my tank, which has a significantly larger footprint to cover.

I would still recommend the Vero 10 for your white LEDs. You can run two in parallel from an LDD-350H and they'll be around 4w each, but still the best color you're gonna get. Three of those, three Luxeon M royals, three blue Rebels, three cyan Rebels, three lime Rebel ES, and six LEDgrouobuy violets and you're all set for a 20 long. 350mA drivers.

Good point. I guess that's what happens when you start drafting boards at 5 in the morning haha.

 

So what's a good spatial compromise between even color blending and shadows?

None preferably lol. I didn't have much separation with my last array and they were all 20mm stars in a row, though some of the colors were on 3up stars.

I might get shot for this but..

Who the hell is this Dave I keep hearing about? Sounds like some god of all thinks hand crafted

For the Veros, BXRC-50G1000-B-24 is the one I want, correct?

 

Also, will rapid led be picking up the Luxeon Ms any time soon?

Link to comment

Doubtful. They haven't yet and the M's aren't exactly new. Steve's and LEDgroupbuy are pretty much the only places worth getting them from AFAIK.

Yes, and no, like Horerczy said.

Hi Dave,

What is the difference between Nano Box Mini Tide and Nano Box V3 array?

 

Thank You

The Mini Tide is the fixture, the array is the LED array that the Tide uses.
