I took several lights out to the car tonight and tried this with my stock TC-R1, E2E, 9AN, Scorpion, hCRI P4 Clicky, hCRI XP-G Clicky and Nichia 119 Haiku. The worst of all was the cool tinted TC-R1 (as most would suspect) not only because of the tint, but also because its XM-L makes it my floodiest light. Next were the other floody lights, but there seemed to be little advantage to the incans in shining through the windshield aside from their inherently narrower focus....had an interesting experience last night when I was driving and don't know what to make of it. When I shine my incan through my windshield I can spotlight anything with little or no reflection in the car. The LED does not seem to throw through the windshield and I get a lot of reflected light back into the car.
In retrospect I should have taken the E1e too, as it has a frosted lens and is both floodier with less of a hotspot, and wider than even my TC-R1.
Then I went outside and started lighting the tops of trees and was surprised when the 9AN (which handily bested my favorite E2E and I also expected to be the best for searching the trees) took back seat to both of the Clicky's. It looked beautiful for all the reasons we love incans, but the extra flood of the Clicky's, Haiku and even the cool (but very high output) TC-R1 made it much easier to see more of what I was looking at. Perceived depth was very good with all lights other than the TC-R1.
Next I did some experiments with shining the lights through a chain-link fence to see if there were any advantages, but the only two opinions I came away with were that cool tints are a no-go and it definitely works better if you're right up to the fence!
I'm going to leave a bunch of the lights in the car and try some more distance comparisons to try and determine what conditions I prefer the incan for. One thing for sure - I love the warmth and even if any of the others go, I have no intentions of ever getting rid of my E2E.
