Eternalight

Its a blackout, You forgot where the batteries are... Your last fancy LED flashlight got lost/stolen/misplaced/broken, AND it needs some ultra rare MV-3534 cell you would never find in a store in a million years anyways.

Introducing: The Eternalight

Powered by a Betacell this small steel bodied Flashlight will most likely never fail when you need it.

The Betacell uses Beta radiation from Tritium gas combined with a special semiconductor diode surface to produce a electric current. It is expected to give power for about 10 YEARS, the LED has a similar useful lifetime.

The Betacell is sealed inside a Ultrahard Biosteel-Epoxy composite which is then permanently sealed inside a Titanuim cannister. The LED and other electronics are sealed inside the case along with the Betacell, a magnetic reed-switch mechanism allows for a TOTALLY sealed unit. Its water-proof, but it won't float. The outer casing is a stainless steel tube with a yellow Radiation symbol emblazoned on it to scare/impress your friends, the front simply exposes the LED's outer expoy surface. The top switch is simply a sliding on/off type. Its diameter is about the same as a 'D' cell battery, with a slightly longer length. Nearly all of its weight is from shielding. Its not 'heavy' but would make a OK paper weight.

Expected costs would be high considering the materials and design, over $100US would be expected. It has a lifetime (10 YEARS) warrenty, should it ever fail it would be replaced.
