Pah, efficiency is overrated. I burn off more power than this thing uses in my BTU cable!
Unfortunately I won’t be able to see the emitter too well behind all that glass but the beautiful circular beam profile should be well worth the price of admission. Heck even in a SMO reflector the effect of the circular die is clearly apparent, lovely stuff.
Interesting that removing the window has changed the tint, perhaps you’re seeing a subtle variation on the dedoming tint shift. Of course a lot less pronounced since the window isn’t directly touching the die, but maybe similar principle.
Slightly different lens/emitter ratio and focal length between these two lights , but I’ll stay optimistic that I’ll acually be able to see the thing in there when it’s done, would be nice.
Interesting, would have thought it might pull more DD, but there’s too many variables at play to really know what’s going on in a light.
Has anyone anywhere done any testing on this emitter to see how far it can be pushed? If not I’ll try do a few safe-range tests to see how it responds. Curious to see if the vF stated in the datasheet is accurate.
All this talk of this gorgeous emitter and I had to look it up at Mouser. They happen to have em in stock in the 5700K version for less than I’ve seen em ever, end of life they say! So I ordered one. The wife will kill me over this stuff some day…
Oi! don’t you all go buying up these beauties before I get a chance to grab one!
I don’t think you’ll get anywhere near a 2000lm Bin out of it unless you go for the CW variant. The NW 5700k seems to be around 1200 at best from what I’ve seen.
Like Dale said these things ain’t that efficient!
The super cool 7000k tint bin numbers give a spewed idea of what these emitters really produce, any XMLs I get that are so blue (low 1A/0D equivalent) usually wander straight into my bin
This is good, it means it’ll run on an 18350 without any problem. That’s my alternate plan. My main goal is to try something that hasn’t been done before. Having trouble obtaining a part, MOQ is 20 pieces at some $660! The alternate plan is looking more and more like the main plan. lol
Well I got a big :bigsmile: on my face today, the SBT-70s arrived!
Just amazing looking emitters.
And a surprisingly small die area. Looks to be somewhere between the apparent die size of a domed and dedomed XML. Closer to a domed Xp-g2 than I thought, and of course the mt-g2 looks like a hulking beast in comparison
And finally, something that looks like it comes straight out of Tron!
This is really interesting actually. The blue leaks out at the edges to give this interesting looking effect. Wonder if this will be visible in the projected image? Maybe I need to stick a blackout window to the emitter “window” to keep the image perfectly clean and round. Could get interesting.
I surely do love how this one looks! Mine is still in it’s little fancy foam padded box.
I can’t wait to see the color of light it produces. Daylight white at 5700K and 90CRI, been dreaming of this one for a long time now. The one I have in my TangsFire 2010 is blue-white, obviously a cooler tint. But that defined circular hot spot is too nice, even in the 2010.
Sure wish I could afford 3 of these to do a triple with. :bigsmile:
