no way !!
The Led Lenser P7 runtime you mention is on low power. I suspect that the usable throw is not 750 ft then? On full power the runtime is around 1.5 hours. With good NiMH the runtime is perhaps a little bit more, but NiMH are not recommended by Led Lenser. I don't actually own a Led Lenser P7, but I googled and read about the runtime on full here:

One of the nice things with DX is that the shipping is free. So you don't have to pay for any shipping at all. And it ships from China. You may have to wait a while (1-3 weeks) before delivery and perhaps pay local VAT if customs feel like it. But then you will have a brighter flashlight with 2 rechareble batteries for less than half of what a P7 costs.
A P7 costs about £50. A X2000, with 2 batteries and charger from DX costs about £22. So you can even buy an extra spare X2000 and still have plenty of money left over for the VAT if needed. Or perhaps buy some other flashlight that use the same type of 18650 batteries?
I got the price for the P7 from here:

I have a Led Lenser P14, a very nice, well built and robust flashlight, and I also have a X2000 from DealExtreme. So I can compare output side-by-side. I believe the P14 on full has a similar output as the P7 on full (but the P14 has much better runtime on full).
The X2000 is actually well built and robust. But that said the P14 feels more robust. I certainly agree that the Led Lensers are well built. However, I have not done any destructive testing. So I don't know which light will break first. Since I use the X2000 much more than the P14, I suspect my X2000 willl die first. So I am considering buying a spare.
With fresh batteries the X2000 is a little brighter, and it is also possible to focus it more compared to the P14. So the X2000 is very noticable a better thrower than the P14. And without testing side-by-side I assume also compared with the P7.
I think that the runtime for the X2000 is comparable with the P7 (on full). Around 1.5 - 2 hours with good output. Both lights are direct driven, and after a while both lights will become dimmer as the batteries discharge.
So to sum it up: For less than half the price of a Led Lenser P7 you get a X2000 with more light, better throw and ALSO a charger and two rechargable batteries.
