The Nuwaii TM-800, 801, 803 X-3 ...... series are very well made head-knockers, but they are not as bright as you might think reading the advertising. There are some previous threads on this forum about this light, and the consensus opinion was that the output was not as much as everyone expected for a 3x3. Definitely not in the category of the Elektrolumens Phazer, UNLESS, you performed the infamous "PVC pipe & 4 C-cell NIMH" mod. That turns it into a BEAST, with of course the added risk of shortening the LED(s) life.
I recently purchased one of these, and I like it just fine. It is just 1/2" shorter than a 3D Maglite, and has the evil appearance and MASS one would expect from a Bash-lite. As for output, I don't know what you own, but comparing it to my existing lights, with all 3 emitters switched on, it has throw range slightly better than my streamlight Propolymer 4AA luxeon, with more coverage at the target area. I like the idea of being able to switch on just 1, or 2, or all 3 emiitters. Some owners expressed dismay that the first click is low power, rather than high, but I don't mind that either.
