Reef Brite XHO BLUE

Don’t quote me on that info, but that’s what I’ve read about the Reefbrite spectrum.

Maybe this will help

I also remember seeing one thread with a spectrum graph somewhere on here

I have a 48” tech led. If you want I can count how many led’s are on it and how far apart they are spaced if it helps

Awesome, thanks! Every little bit helps

That guy also claims a single type of blue diodes...

LOL'ing at almost everyone completely dodging the actual question and instead jumping to picture advice.

Personal opinion here. Reef Brites command a high price because they're popular. Here's what we KNOW. They will tell you NOTHING about their diodes. Not a wavelength, not a brand, certainly not binning information. So it is reasonable to assume they're bulk quality imports from the cheapest bidder. if they fashioned their own diodes from the substrate up like Kessil does, or assemble their own multichips like Orphek, or even just used top bin CREE or Philips rebel ES or Luxeon dioes, they'd generally state it as a selling point. Most brands are proud to tell you about the source of their diodes. Reef Brite keeps that under secrecy, so it is reasonable to assume that they're probably not the highest efficiency diodes out there. Just a tought.

But from everything you look at over the years there seems to be two different generations of Reef Brites. Years back when they first came out you can distinctly see a blue and a violet combination in the strips. Presumably a 450 nm and 420 nm diode arrangement. The newer ones appear to have dropped the 420 nm diodes. It's also a reasonable assumption that they use a 450 diode strictly, as those tend to produce the best fluorescence and the color is generally pretty unmistakable. 460-470 has a different look to it.

Sorry. I gave you a bunch of assumptions here without any facts, but they wont provide those facts so we have to make educated guesses. Based on what we DONT know, I have a hard time understanding why they command such a high price when there are comparable alternatives out there for much less expensive....but I digress. they're well loved and I dont hear a whole lot of negative reviews of them.

They APPEAR to just be 450 nm diodes put inside a small reflector (almost like a single reflector strip from an ATI sunpower, fixed into an aluminum channel.

Thanks for posting; This is some good food for thought.

So, I'll fashion a strip together with 450nm diodes and see what that produces for me

Always used to be Edison Opto ES series LEDs. But then again, they are in generic packages, so they could be almost anything at this point. Reason I say that they are most likely Edison ES series is that we (Nanocustoms, before we went belly up) used the same strips in our products back in the day.

Speculation for discussion..
