Damn! Been out of the flashlight buying game for a bit and come back to miss this by days!
If there’s any chance I can sneak on to the end of the group buy list (or anyone’s ordered too many!) Please let me know. Dan (London) Cheers…
I use IMGUR, per hour parce that works well
That means I have to break out all the heavy iron from their storage places. That’s a lot of work. But eventually, it will be done. I’m under the impression that typical XBO/Xenon Short Arc lamps have CRI’s in the 90’s. It would be fun to confirm this.
Seriously though, I would be more than happy to measure lots of light sources for people if they send them to me. Send complete lights, bare LED’s, commercial bulbs, whatever you might want measured. I have programmable current limiting power supplies so I can power up bare sources so to speak. Example: LED’s on stars as long as I can get a reasonable sized contact area or u attach wires to it. I can provide Kelvin and CRI/extended CRI measurements and, although I do not quite understand them yet, info on where the source is in relation to:
CIE1976
CIE1931(CIE1964)
XYZ
xyz
u’v’
λp (Peak wavelength)
λd (Dominant wavelength)
Pe (Purity)
PPFD
Maybe a database/repository of sources and their measurements could be kept on the site.
Here is a video of how they might make the reflector, probably using more CNC and less human intervention…
Thats a pretty cool video on making a reflector, but I really dont think most of the reflectors in the lights we use are made like that. If you notice a page back the pic of the GT reflector, p60, c8 and s2, I would say all 4 of those are turned down on a lathe, not rolled out like in the video.
The GT’s reflector is NOT made by spinning.
i want that 2000$ toy so bad 
YOU SIR ARE JUST A SPAMMER!!!
Today I illuminated a water tower in 2,08km with the BLF GT :sunglasses:

Thanks for sharing Alux.
I’ll have to see if I get one (I was just outside of the 1500), but I may try an emitter swap on it too. Ill let you know if it goes okay.
They don’t provide tracking codes, only in the beginning US buyer got their codes. After that, no codes. Not very professional.
Maybe not, but I think they kind of bit off more then they could chew on this group buy. They wanted the first 555 to put a deposit to prove there was interest. I think they were skeptical that they would actually sell 555, not to mention 1500+.
Companies like lumintop are not used to selling to individual people either. They typically only sell wholesale to retailers. Yes, Neil is used to retail selling and shipping, but this is pretty large scale considering all of the steps involved from manufacturing to the end results of getting them shipped
so you mean there is a chance my light is on the way :money_mouth_face:
That could be the explanation for it, but nevertheless it’s a bit annoying there is no communication about this.
yes, that’s the exiting part of it, every day is a surprise. You never know when the DHL or local post car stops at your house with a huge box. :)
The problem is, every day the mail truck stops at my house, so every day i get a littlebit excited, and think, would it be for me? but 9 out of 10 times he walks to my neighbors…
The other time its my wife who ordered online stuff :person_facepalming:
