Just a comment about the 'lumen' ratings:
Everything WRM said is right, but the article he linked is actually a year old and the technology has moved. We make very small batches of these torches so that we are never more than a month away from using new LED technology.
The current (standard) Spikelights have a maximum of about 700 lumens (up from 500 last year). We can also do a good 1200 lumen version (up from 800 last year) but it can't maintain that for long periods of time. Beyond that the quality of the light actually goes down with more lumens. The highest I ever made was almost 3000 lumens. I promise you that the 700 lumen version is better.
As already commented, I try to avoid such figures because they are poorly understood and many manufacturers are dishonest.
The ANSI standard is the best, but it does give some strange results. For example, by ANSI standards the Spikelight would have a range of about 600m (2000 ft). In the real world, with my bare eyes, I can only see things at 300m (1000ft). So this is the rating I give it.
