Just took some pictures of a couple of emitters, first out is the beloved Cree XR-E in the wild:
Notice the copper colored border around the newer and smaller EZ900 die, right slide showing an antique XR-E with the phosphor sprayed everywhere.
Next up is a XR-C posing next to the older XR-E:
Differences includes a smaller die and half as many bond wires.
Poor cool white XP-E, got extracted and replaced from within a Trustfire F-23.
Die looks the same as in the EZ900 XR-E but there is no copper border present around it.
A couple pictures showing emitters in captivity:
Tell tale differences between XP-E and XP-G includes the number of segments the die is divided in, three vs four, the difference in die size and the absence of the three dark dots around the XP-G die.
Last but not least, a newer addition to the zoo, a Luminus SST-50 (actually a SSR-50, but they look the same anyway)
Whatever you do, do not touch the gray plastic part that holds the lens in place! The dome pops off at the drop of a hat if you do
Thanks Spambot for this excellent contribution! An excellent reference here for all of us. Very well done. Frontpage'd and Sticky'd.
By any chance could you include a picture of a light with an XR-C? The XR-C appears to be a popular choice for manufacturers when they decide to "get cheap" with a popular product that used to have a more modern emitter.
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.
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.
