Been playing with the not terribly useful USB "Microsocope". It probably works rather better with the supplied Windows software but the Windows box is getting annoyigly noisy - time to swap out some fans.
Very nice and very usefull pictures. Good post.

For decent, if small, emitter photos you can use digikey.
As always, AWESOME pics there Don!
Really really nice pictures Don! : )
Great photos!
These are what appear to be in the DaZong Tong tiny little light. Still not figured out how to extract the TIR optic without killing it but my best guess is that these are the LEDs in it.
That little DaZong Ton looks interesting… I looked everywhere to buy one, but had no luck. Woudl you knwo where i coudl aquire one or two of these ?
Is this warm glow a property of high CRI or just any T4? I thought UV light would make all phosphors glow.
Thats odd. Do you know the wavelength of your UV?
Is that how it looks to your eye? My eye sees more phosphor glow, less blue / uv then my camera.
According the StreamLight site, it’s 365 NM. It seems to be in a good range because different denominations of paper money show different colors clearly. Other “UV” lights I tried didn’t work as well.
Yes, that’s exactly how they look. The T4 glows brighter if I move the UV closer while the U2 does nothing.
They always seem to use blue leds under the phosphor so its looks like in maximizing it for blue the cool white just doesn’t luminesce as low as 365.
Streamlight Stylus UV ?
That’s the one.
With a cheap (unknown wavelength) UV light, the U2 barely glows white but still nowhere near as bright as the T4 under the same light.
Does your cheap UV light put out a lot of purple? Light yellow glasses cut the purple really well. Plus protects your eyes. Damage is cumulative.
Mouseover, XM-L CW vs XP-G2 3C
Three images: Initial UV, mouseout white, mouseover UV with yellow camera filter. (initial UV image only returns on page reload) Doesn’t show the dramatic tint difference that can be seen by eye. Also brighter by eye.
UV is about 400-410nm. ‘1W’ emitter in an Ultrafire WF-602C 1*AAA both from dx many years ago.
Yes, it’s very purple. I don’t have yellow glasses but your image without the filter looks about the same (maybe a little brighter) as what I’m seeing.
The pictures in OP are broken for me.
This is a very old thread with oldschool emitters, try here for a source that is still being updated with the latest leds:
