defloyd77,
I just got mine today...fast shipping from Batteryjunction as usual. I have never had a nuwai light before, but I like my other 2 rebel lights (Fenix P3D and LP M1-R) so I thought I would give it a try.
The light feels worth about what I paid for it...$29. If it is putting out 90 lumens, than my P3D and M1-R are putting out about 300. I would say 40+ is more realistic. It is slightly brighter than my MMagled3AA and its brightness is between the P3DR100's medium and high settings. (high not turbo)
It does have a simple push for momentary and twist for constant on switch. It also has a decent tint with a nice SF like beam with a smooth spot and clean spill beam.
Is it worth buying? Well.....yes, if you want a nice inexpensive AA light with decent illumination for around the house tasks. Again, it is a $29 light. It is not a LP M3, nor is it as bright as one, or as versatile. If you have $50-$75, you can buy much nicer lights. But again, it is a decent light for the money. Just do not believe the specs.
