I tend to go in cycles with my lights. The lights I use the most are my favorites at that particular time. They might be the ones I use the most now, but weren't 3 months ago and might not be 3 months from now.
My current favorites:
1. Sinner Cypreus Tri-EDC. This is a custom single-18650 tube-style host made entirely of copper with a solid copper pill. The entire light is fairly small at 103mm long and 24mm wide. I installed a 3-mode Nanjg 105c driver from Mountain Electronics with off-time memory. I stripped all the 7135 chips off the driver and replaced it with a FET. The emitter is a 20mm copper Noctigon with triple dedomed XPL neutral. This is easily my brightest light. Based on a similar build someone else did on a fresh Samsung 25r INR cell, the light should be drawing around 13 amps at max power (4.3 amps per emitter) and outputting around 4000 lumens. My luxmeter measured it at 25k lux... very impressive for a small triple. Even at 25% power I estimate it's outputting around 1000 lumens.
The biggest downside of this build is heat. The copper head becomes too hot to touch after 20-30 seconds. This is not a light you'd want to accidentally turn on in your pocket as you'd quickly have a fire. I'm thinking I need to replace the driver with one with a shorter turbo timer. (current one has a 2 minute timer, but 30 seconds is probably more appropriate). Also, being made completely from copper, this light is substantially heavier in the pocket than comparable sized aluminum lights.
2. Zebralight SC62w. All around great light. Lightweight, bright, great tint, great runtimes, nice UI. Not much more to say.
3. Modded Aleto N8. Single 18650 cheapie zoomie very heavily modded. Much brigher than stock with a wider flood, more throw, electronic sideswitch, shorter length, and great grip.
