For Zoolander- the new light is something I pimped up from another dude's experimental light. If you missed it:

I'm afraid it's a one-off. There may be a kit coming out soon though.
Here's the thread on the light-geek forum.

Basically 800 lumens with a nice tight beam, lighter than an Apex (70-130 lumens), tiny battery goes 90 min at full, 7 hours on medium, weeks on low. Easy custom dim mode too. Takes my big batteries also for multi-day burn, or AAs.
I like it better than Ay-ups as it's smaller, almost twice as powerful, and burns far longer on the lower power modes, not to mention the option of bigger batteries.
Also only cost me just over $200 plus some geekery, including battery.
I've been commuting on medium power.
