The main cause of the initial lumen loss is heat build up at the LED.
A few quick bursts, allowing the battery to rest in between should give a similar result but as the battery begins to lose charge, its peak also probably loses some power too.
I can measure it precisely when I have a chance, perhaps sometime over the weekend.
The existing trit slots would work fine, but would need one more added to the body so you know which position you are in.
Allow me to reiterate though that I think you will get along just fine, even with your eyes closed
Trits are always cool
For now, the trits will have to be a DIY thing as there are restrictions on radioactive isotopes where I'm at, unless some trits magically arrive in the post.
