1x18500 or 1x17500-cell (1.5x123A) flashlights?

Are there any?

Or:

Is there a 1x123A light that can accept a Surefire A14 extender tube to turn it into a 1x17500?

Re: 1 x 18500 or 1 x 17500-cell flashlights?

OK, I just discovered the Aleph 1.5X123 (1x17500) Power Pack. What would I have to add to make it a complete light?

Update: OK, now I found complete 1.5 x 123A lights that use an Aleph 1 head or Aleph 2 head. At $175+, I'm afraid these are too rich for my blood.

Don't the SF KL LED heads fit onto the Aleph tubes? Not sure what voltages are involved, so someone needs to chip in here. Just an idea.

Hi Paul, the Mr Bulk (Charlie Wong)'s LionHeart was an 18500 sized light, designed to run off a single 150A Pila.
McGizmo (Don McLeish)'s stuff is awesome, and to complete the 1.5 x 123 tube you need a tailswitch (two-stage, & lots of versions), a head (at least 3 varieties), and a "light engine", which is a custom converter/driver/led built to be easily exchanged between diifferent Aleph lights.
The switches, bodies and heads all mate with the Surefire E-Series, so lots of fun can be had.....
Yup. it costs money, but we're talking the best custom lights on this planet...

If I'm not mistaken, all Aleph parts are physically compatible with Surefire E-Series parts, so you can mix and match whatever works for you. The Aleph series is generally superior, however.
