One thing that PentagonLight touches on is the fact that Xenon bulbs
have greater throw than LED's. I have always believed that with my
Surefire C2.
When I replaced my 65 lumen P60 xenon drop in with the SF P60L, the LED
drop in was "brighter" especially for lighting up a room but once outside
the xenon had noticeably greater "throw" after 100 ft.
It's nice that PentagonLight confirms this and explains why xenon lights
are still important to the company. I think much "brighter" LED's in the 150
lumen to 200 lumen range is what it takes to equal the throw of a 65
lumen drop in outside.
It's a shame Surefire dropped the C2 and C3 xenon lights, now if you want
that awesome design you will be forced to buy a LED C2 at close to $150
when the dealers run out of the xenon version.
I like PentegonLight as a company and I hope internet dealers like BatteryJunction start to carry them as a whole.
