Fred, leaving the sphere such exposed was not planned, but the sphere was too big to go deeper into the reflector.
But I have to say that I really love the look of this "eyeball"
The top of the sphere is still behind the front metal ring so I do not see a too big risk.
Thanks so much again for making this happen, even it take so long that the sphere already lost nearly half of it's brightness ;-)
It was totally worth the wait!
First offers are already coming per PM, but as long as there is not a really insane one this luce will be a for life keeper...
I don't think so, but they still make the Betalight self luminous torches so that tells me they probably still make fresh 22mm discs. I was thinking of buying one and removing the disc. They are usually $149 on ebay so buying the disc by itself would be much better price-wise. At least, I hope it would.
