home made solarforce style lantern for a fenix

Well I wanted a lantern attachment like the solarforce for the L2 and Surefire lights for my fenix l2d so here it is:


Its just a clear cap from a drink bottle and inside it, I made a cone. In the foreground, theres a cone thats made from aluminium foil but I used a 92% reflective mylar instead.

Heres what it looks like on the l2d, and an action shot:



It works but the glare ..

anyway some light meter measurements:
0 degrees at 1.2metre 47 lux
45 degrees at 1.2metre 21 lux
90 degrees at 1.2metre 26 lux

using the aluminium foil cone
0 degrees at 1.2metre 37 lux
45 degrees at 1.2metre 36 lux
90 degrees at 1.2metre 18 lux

using the rude looking fenix diffuser tip
0 degrees at 1.2metre 21 lux
45 degrees at 1.2metre 22 lux
90 degrees at 1.2metre 21 lux

as you can guess, its not a very even spread and theres a bit of light spillage. I might try a silvery christmas tree ball the next time I think

Why not just use the Fenix differ instead. I've used it in the house and in camping and it works quite well. What's the advantage of this set up?

pretty much to squeeze a bit more light out of the lantern.

Just had a thought, a mini disco ball. Be great if it spins too.

That's cool. Nice idea, but one suggestion: Put some more of that mylar on one half of the inside of the cap, so you get a directional floodlight, and you can see what you want, and not be blinded. At any rate, that's what I'd do. I've never liked 360* lanterns, cause they blind you, which makes their illumination for me, anyway, pretty pointless, when compared to a regular flashlight.
