Get a laser. Has the farthest throw of any light!Hello every one I want to buy an EDC flashlight with longest throw.
What are your suggestions and advice?
Please help me find my dream light!
Deft EDC from omglumens.com
+1 for the DEFT EDC; you can't beat an aspheric lens for throw. Over two football fields of hotspot from a pocket light is pretty amazing.
how many lumens does that thing do ?
Currently, we have this problem where the more powerful emitters like the XM-L are too large in size at 2mmx2mm relative to a compact pocket size 1 inch head/reflector for Every Day Carry.
Thus we end up with a very floody beam, with diminished throw.
Some manufacturers like Omglumens overcome this by putting in an old tiny emitter like a Cree XP-C Q4, which is tiny relative to an EDC compact 1 inch head, so maximises throw, but because it is so tiny, it only puts out something like 100 lumens.
I wonder if we can put a big XM-L emitter with 750 whopping lumens etc, onto a compact every day carry 1 inch head/reflector - yes, lots of flood - too much in fact.
However, then use an aspherical lens to focus the light beam to give normal flood/throw ratios???
You end up with a big image of the die in throw mode. It's still not as bright as an XRE for throw because the surface brightness of an XM-L is lower than the XRE.
I typically use my EDC for brief occasional use indoors. I'm running a modded Sipik SK58 with a 2.8 amp driver and XM-L. Someone else with a similar setup measured a similar light at 14k lux and the battery life is only 12 minutes on max (my guess is probably around 700 lumens out the front). In contrast, a cheap budget EDC zooming flashlight, the EDI-T T11 with an XRE produces 19k lux at less than 200 lumens for around half an hour.
