    HO-A2 focus issues ... [FIXED]

    I own a Surefire A2 (round body) and am having focus issues with a HO-A2 from Lumensfactory. It doesn't produce a nice spot like the stock bulb, meaning that the height of the filament in the reflector isn't correct. I even got a replacement from Lumensfactory, but this didn't help. Here is a...

    Portable thrower comparison with lots of graphs

    Here I have created a google spreadsheet which compares the throw of all the portable (battery powered and handheld) throwers which I have found out about through the years. It doesn't matter if they are stock or modded or what light source they have. It also includes many different graphs for...

    Project Excalibur - Next Generation LED Thrower (many pics)

    You should probably get some coffee, this story is long... This is an English repost of my thread in the German TLF forum. Introduction: A few years ago I was lucky to be able to cheaply purchase an old, used Maxabeam head. The Maxabeam is the farthest throwing, commercially available...

    Sold/Expired WTB: Surefire A2 white or red - preferrably in EU

    I am looking for a working Surefire A2 with red or white LEDs (EDIT: any color!) (or an aftermarket LED ring). It should work flawlessly and the bulb shouldn't fail right away. A few scratches on the body wouldn't bother me if the price reflects that. Reflector and lens should be in optimal...

    I just did some ceiling bounce measurements with my DX lux meter. My ceiling is white and has a rough texture to it. The lights all stood in the same pace on the floor and the lux meter's sensor was about 1 foot away from the lights. The lights were either tail standing or pressed onto the...

    Armytek Predator modded with Nichia 219

    Yesterday I switched out the emitter in my Predator. Mine had the cool white 1C XP-G (with smooth reflector). I took some pictures (not enough unfortunately) in case anybody wants to do the same thing. Gunga over in the CPFMP has also done this before (here). 1. First I too apart the light...

    Reflector for XM-L D-Mag

    Hi, a while ago I bought a custom 1D Mag with a T6 XM-L and a copper heat-sink here. I have since modded the 2.8A driver to 4.2A and bought some imr 26500s for it. It's pretty bright now. My problem is that it has a Solarforce Masterpiece (Pro-1?) smo reflector. The problem is that this...

    Help with modding Jetbeam M1X with neutral MC-E

    Hi, like the title says i want mod my M1X with a neutral tinted Cree MC-E. As far as I can tell it should be relatively easy for an experienced modder. Unfortunately I'm not one of those :laughing:. I want to use a Cree K-bin MC-E with a 5A-Tint. Here is what I already know: -The MC-E is...
