I bought the Pro ZX-1. 1200 lumes. Then I called and left a voice mail message asking about their larger Pro ZX-1XL and when it is going to be in stock. Someone called me back with 60 minutes that night *7pm eastern. Told me my answer. When it was in stock I bought it.
I keep the smaller one in my car's glove box (Florida heat does not reduce the battery life). The other one Pro ZX-1Xl is on my gun belt (law enforcement). It is also 1200 Lumes. Both are rugged. Both are just as advertised. One improvement they said they might make in the future is to "remember" the last setting you used for the next time you turn it on. So it will automatically go to the last setting you used (high, med, low, flash, sos).
It is rugged. Used it for 8 months, no issues with flashlights OR with batteries being recharged as needed. Dropped the larger one twice, dirt once and cement sidewalk once. Still works fine, but end is scratched from the cement drop. I hate that I did that, but I was chasing someone and it slipped from my hand. I even have it in a flashlight case on my 2.25" gun belt. The one in my glove box is just wrapped in a small cloth to protect it from any scratches.
Someone said 200 lumes. NOT TRUE at all. It is 1200. IF less, then you didn't buy the real ones, but a knock off non-name brand.
