Вот что я нашел:
I hacked my L&M Vega to use a 100 lm/W Cree star (dealextreme.com) — as simple as unscrew the bezel (reverse threaded), unscrew and unsolder the Lumileds LED, screw and solder in the Cree. The beam pattern is totally changed but the brightness is vastly more. I have probably 50-100 hours use on it and can’t figure out why L&M is still selling them with the 35 lm/W emitters.

Stella разбирается?
