My favorite modded light tends to change depending on what I most recently worked on haha!
I'm liking the DQG Tiny III as a mod host for small triples. Here's one I completed last week. It is dinged up because I made this out of leftover parts from an earlier mod. I dinged it up fruitlessly trying to remove the head. Eventually, I just did the mod without removing the head.
Entire light with an Efest 35a flat top installed is 87mm long x 29mm wide at the head.
The pictures show the external heatsink I added around the head. This helps absorb some of the heat while also insulating the hand from the hottest part of the head.
I used the original switch plunger in another mod. The copper plunger visible in the picture is the replacement I made from sheet copper. Around the plunger is a nickel plated brass washer that protects the light from accidental pocket activation.
The light is currently equipped with a FET e-switch driver with moppydrv firmware from Mountain Electronics. Emitters are triple XPL HI 5000K.
Currently set to mode group 7, which gives the following ouputs:
* moonlight
* 30% power - 930 lumens for 55 minutes. However as this is a FET driver, output isn't regulated and declines as voltage goes down.
* 100% power - 3100 lumens for 10 seconds followed by 1550 lumens. Again output declines as voltage drops.
I really like Moppydrv firmware as it has 16 user programmable mode groups and a user programmable turbo timer with gradual rampdown to 50%.
At full power this pill-less light gets excessively hot incredibly fast. If I wanted longer runtimes at turbo I'd have to place something over the top of the head and switch to help insulate the fingers (perhaps Duracoat paint, or maybe make a rubber cover out of Sugru moldable glue).
