I’ve always been pretty skeptical about the lumens companies print on their flashlights – but this one just might be accurate. There isn’t really an official standardized test method for measuring lumens, so it probably won’t accurately match another company’s claim of lumens. Judging the tight beam of this light, I think they actually are hitting pretty close to the mark. Compared to other high brightness single LED lights, this one fares very well and leans on the brighter side of life.
The Revtronic F30B comes with a single 18650 and a charger. The battery I received was reading absolutely no voltage – but after a full day of charging, and a full day of sitting, it was holding its full charge.
Doing a comparison of measured lux from this and a couple other “high power” led torches I have, this one measured the highest by far, due mostly to the much tighter beam. This torch has a very deep reflector which gives a much further throw of light. It has 5 modes, High, medium, low power, SOS, and strobe. The torch comes apart into 4 main pieces: the end cap or button, battery compartment, LED module, and lens cap. The module measures 1.5″ diameter and 1.5″ deep. Each connection has an o-ring and some grease on the threads for waterproofing.
Overall, this torch is a good very bright LED flashlight that also has great potential for modding (if you’re into that sort of thing).
