I personally prefer the 5700dd when daily EDC around the city for work. When I walk the dogs at night I prefer the 3500dd more as there's a lot of trees and bushes at my park. The warmer tint makes the colors vibrant at night for me.

I currently have the SC53c N and the H53c N paired with IKEA ladda 2450 and 1900 batteries. I really like them both, they might not seem to have "enough" output for some. As for me I hardly need anything more than 200lumens for the daily task that I do. Don't get me wrong though, I enjoy REALLY bright lights too lol. They're also built like a tank as well.

Thank you! love seeing your post and data input that I've come across on BLF

No this is like my third time with the zebras. I used a really thin 4mm flat head driver and went around in circles until the bezel popped off. I then used my hot air for reflowing. As for the potting I only put back the potting on the underside of it. I would like to put the top potting back on but I don't think not possible. I'm sure modding it would lose some of its "tankiness" that ZL is known for. I would like to see if I can find some electronic potting mix to re-do it.

Wow looks great!
