I built a 6 foot long 8 x XML aluminum light bar for my basement utility room. All are wired in series and driven by an AC to DC 3A 24V converter. I didnt think much of it while assembling because I was using a bunch of spare parts to throw it all together. One of the emitters is a dingy angry blue emitter that keeps blinking and shorting out the system. Yup, you guessed it… laticebright. I dont know which flashlight it came from, but these things cant even sustain 2.9 amps on a large aluminum heat sink. 7 nice bright CW cree XML’s and one POS LB that looks less than half as bright as the others in the series string… and what a nasty blue tint it has. :Sp Like the rest of you, I’ll be using my magnifying glass from now on to see which emitters land in the garbage can.
This is still in the pill of a “TrustFire 878 Cree XM-L U2 5-Mode 900LM Cool White LED Flashlight”, from FastTech, $10.24. Its best feature is that it takes 1*26650 / 4*AAA. I use it with a diffuser as an overhead light with 26650, and I gave the 4*AAA holder in another 26650 light.
I took it with the low magnification of an old school compound microscope that I got at a yard sale. So the image is inverted. The auto-focus of my camera works in combination with other optical devices. (It must search for the focus that gives greatest detail.)
I think the LED is fake. Do others agree? The tops of the bond wire pads are round, but there is no phosphor visible below them.
I had a (somewhat more powerful and specialized) compound microscope to play with as a child, until my father sold it. My grandfather had a much older one, probably from when he was a medical student. It was mostly brass. He had brass extension tubes to fit his F 2.0 camera to it, to take pictures. It is much easier with modern stuff, but it helps to know it can be done. These ordinary compound microscopes are usually used to view biological specimens lighted from below, but they work just as well with opaque things lighted from above, as long as the light gets past the objective lens and its tube.
Microscopes have advanced and proliferated enormously since then, even showing individual atoms, but we only need old optical types here.

Review summary:
Ok for the price. Nice configuration but not the advertized Cree LED.
Pros:
Cheap. I like the 4 x AAA holder when lithium ion cells are not wanted. It was my first zoom 26650 light. Compact.
Cons:
Lattice Bright LED instead of the advertised Cree XM-L. I needed a microscope to be sure, but I could also have found that if I had light measuring equipment.

So basically Fasttech rejected your review, because you exposed them for falsifying the specs for the light? (meaning they advertise it as Cree emitters, while it actually has Latticebright knock-offs in it.
it would be better now if all the Chinese sellers that sell any sub $20 whatever-fire lights without the LED. Putting a Crappicebright LED in them and claiming that the light has a Cree is just pure BS. The latticebright leds are trash as we learned, all have horrible tint, low output, low efficiency,suck power, can’t handle high amps, etc. These lights sold with them are garbage until the LB rash is removed an a good real LED from Cree or Nichia is modded in them. I have not purchased one of these lights since early last fall when the whole Latticebright scam began to surface to a noticeable level.
Hmm maybe I have a nice idea to do something
Let me play around with it in my head and I start a new thread
For me the game has changed a bit after being put on a blacklist, I will inform you guys in the new thread
The FastTech light with the fake LED is no longer available. I don’t know if that is because of me or if they ran out of them earlier. I hope they will try to avoid similar embarrassments by checking their products. They generally have a good reputation and I expect they will continue to try to protect it.
