Solid Pill Vs Hollow Pill

[hank]

from trying to consolidate all ZeusRay posts
(this is the DealMetic guy who knows nothing about flashlights, but who got us a solid pill —- 8mm thick (more than a quarter inch of solid aluminum) behind the emitter.

Discussion continued toward further improvements, but somehow instead they really screwed the next several revisions up, cutting more metal out of the pill, sticking in a metal shim with the result that lights were flashing once when turned on then dead, presumably overheating but possibly the much cheaper driver they’d swapped in.

Replying in the conversation about that, the DealMetic userid (whoever that is) posted this:

thank you for all the suggestion.
the engineer reply back to us saying to use 100% copper will easily rust,
so it had use the brass, since in chinese they all call it name the same,
just with a color named different, that is why it use copper instead of brass,
will look into that, any suggestion from rust if they use copper, will send this advice to zeusray.
also, about the space on the pill, engineer reply a long note on why it need the space,
they say it is good for the heat radiation, but already request a model come with 8mm tick to test,
and work compare with the one it out to the market.

It’s almost literature, along the lines of
