Wait!! What if we don’t want to be cured?!
Isn’t that item and the others mutually exclusive? If I take the cure, what would I want all that flashlight stuff for?! If I take the flashlight prizes then I’m going to run from your “cure”!
One day it might save your marriage. :bigsmile:

I actually exercise good self control with flashlight purchases, I need no cure.
What diameter tailcap board for a 3 cell soup can? Parallel 3 x 18650?
This would be something you’re in need of for one of your lights?

Parallel 18650’s, I’m working on designing a light, so there are no specific requirements for diameter of the board, but it needs to be designed for high amps/low resistance. Good springs would be nice, but not a necessity as they will be bridged with 18ga wire.

I love the light to cure my problem, but I like the other items even better!
Great giveaway, and congrats on your 500 posts. I agree, this is a great community. Thanks.
I’m fairly sure the focal length is going to be longer than 100mm being only 19.5mm thick. I’ll give you credit for trying when I update the list.

i have worked in an optical industry for a year and man these glass lenses are

Or you can find hi quality optics in those old projection tv’s for free if you know where to look, they are also big.
