Three Flashlight Ideas.

[Tecmo]

1. A twisty flashlight with a floody beam. Since there is no clicky at the end of the tailcap, a aspheric lens is hidden at the tail end. Unscrew the front bezel and aspheric at the end and interchange them for throw.

2. Since we have 3xXM-L lights why not have 2xXM-L which is plenty of light, and the third LED with a XP-E with an aspheric lens. You could have just the xml or xre lit at once, or all 3 through a unique UI of some sort.

3. Drive a XP-C hard like in the DEFT EDC and stick it in a 1xAA light like the Romisen RC-G2 for a real cheap pocket thrower.

How about a battery tube with a throwy head on one end and a floody head on the other. Twist one head or the other to activate that head.

Or put a side-clicky on it with 3 modes - flood, throw, or both so you can burn the candle at both ends.

I like those ideas.

I'm actually wondering if I can get an aspheric modded to project a round image instead of the image of the LED by some type of secondary means.

I think that a hybrid aspheric design will create the ultimate thrower.

I wonder if the Cree Q5 can be overdriven as succesfully as the LED in the Deft.

And I also wonder if the XM-L can be pre focused to project a round image through the aspheric- I've read that aspherics waste some light but if you start with 800 or so Lumens from a 2.8 amp XM-L and end up with 600 OTF Lumens through the Lensing System and can throw 500 meters- that's my goal.

By the way is the XP C driven at 1.4 amps brighter and better for throw than the Q5 XRE at same overdriven amperage?

Burn the candle at both ends . Classic .

The surface brightness of the XP-C is a little brighter than the XR-E as it is a smaller die. It isn’t rated for as much current but if you bond it to a copper heatsink as in the DEFT EDC apparently it can take it. Doing so is not easy however.



When you are talking about a XM-L and starting out with 800 lumens and ending up with 600 lumens through your “lensing system” you are missing the point. Throw isn’t about lumens. It’s about lux. The XM-L emitter doesn’t have the surface brightness of the XR-E so it’s not going to throw further regardless of how you focus it.



If you don’t like the look of the spot in the shape of an emitter you can slightly unfocus the aspheric and round it off. You will lose some throw but you will have a round (and larger) hotspot so the trade-off may be worth it depending on your uses.
