context is at post #291 today, in the trying to consolidate all ZeusRay posts
Summed up below.
> what color is the wall?
Of the three pictures, the darker of the three where you can see a wrinkle upper left, and some scrapes on the surface, is projected on foamcore board (white)
The other two are projected on white drafting paper taped up on the wall
All done in a dark room — with the flashight at bright or medium, the speckling is easy to see with the eyeball but overexposed with the camera
The pictures are taken with the light at low level. I’ll fiddle with the camera and try for better images later.
No big deal here, I basically wondered if this could be a bad batch of cheap emitters that someone might recognize.
They all are supposed to be
History in brief from my point of view:
The first version of that flashlight (ZeusRay from DealMetic) was excellent and got widespread applause (“solid pillow” meaning solid thick pill, great heatsinking.
That was improved over their default by using an “XML-L2” and a “solid pillow hole” — trouble with English but really good lights.
The second batch I and others got from DealMetic had overcut the pill depth so there was a hole behind emitter filled with a loose aluminum shim without heatsinking — many of those lights failed fast;
— somewhere in there others got some that have worked fine that they haven’t taken apart —-
this is the third version I’ve seen, it came yesterday, I’d expected one as a replacement for one that failed.
(The other one that also arrived yesterday I ordered from what appears to be a different company using the same product photos, at a higher price — they use the same website behind their pages. Different shipping envelope, same product).
Comparing my first version to the third — the emitters all have the grid of dark spots (XM-L2). The first version is a brighter and more blue-white light.
The third version has the same grid of dark spots, is less bright at full, and has that yellowish-with-red-purple color.
Funny thing — set up all three with batteries that are equal and swapped batteries around to make sure that’s not a difference —
With all three lights shining on the same piece of white paper — the images of the two new ones in the viewfinder strobe like crazy, the original (blue-whiter) image doesn’t.
I guess it could just be a warmer batch of emitters — or maybe the a difference in the driver or both
