Okay, I was over thinking it. It’s a simple thing. They usually go by the dimensions of the emitter base.
All 70 and 70.2 are 7mm by 7mm aka 7070.
All XML, XML2, SST-40, 50 and 50.2 are 5mm by 5mm aka 5050
All XHP35, XHP35.2, XPG, XPG2, XPG3, XPL are 3.45 by 3.45, but we call it 3.5 x 3.5 aka 3535.
Nichia 219 and 319 are actual 3535.
The new version Luxeon V are an odd duck at 4040.
So it’s just a matter of matching the package to the pads on the mcpcb.
With the 3535 they just have 2 electrical pads. They can run a 3v xpl, etc… or a 12v xhp35 because it’s 4 dies are wired in series. So you send 3v to an xpl and 12v to a xhp35.
Now the 5050 and 7070 are a bit tricky as you can run them at either 6v or 12v. This is determined by the mcpcb and it’s pad arraignment. You need the right mcpcb for your voltage needs on the 5050 and 7070.
Hopefully that’s enough info for you. We’ve talked extensively about mcpcb pads and the different types of voltage setups back in the GT thread and elsewhere. It helps to use pictures to explain that.
Kingjohn, if you want to keep a list of all the package and die sizes of the most common emitters, just take a screenshot of this LIST to keep with you. This is what I do so that I can quickly see all the details that I need.
I see they’ve added new emitters and it now has links. Cool.
The final set of emails for the neutral white GT70 and conversion kits will be going out next week. So if you want in, now is the time to sign up. The google form will be disabled when the emails go out.
At that point the only way to get in will be to PM me or Jason for the details manually.
Received the BLF GT CW this past week. Customs opened the box but everything was there and in great condition.
This is my first BLF GT - it’s much larger than I thought! Works great with some 30Q batteries. Everything is very well built and intuitive (great interface). Thank you for organizing this!
That’s the one I mentioned earlier. I received it just the other day. I plan to install it in the next couple of days. I don’t think there’s any way to know for sure what the color tint is but I’ll tell you if I see any green in it.
Do you plan to dedome this, or have you ordered a dedomed one?
Thanks a lot.
Opening flashlight, (reflector without fingerprints, dust…), removing, reflowing, mounting, centering an new LED, if first one is green, is about some hours work for me, I´m doing this not so often…
so it would be better for me to know, what result could be.
Whitwallshot in “green” is no problem for me, but I like warmer tint (more yellow or red) in nature…
