My primary is a Princeton Tec Shockwave LED, nice big white beam, long battery life, dependable "lamps". No problem operating the switch with 5mm gloves. 2 power levels.
My back-up and major daylight is the Princeton Tec, Tec 4000, a 4 C-cell lamp. A very adequate back-up. I got caught out in the dark once on an evening dive and we made the entire return swim in the dark with this light and it was very adequate. The switch is a non issue in 5mm gloves.
I do have a Princeton tec, Tec 40 that I use as a minimal dive light durng the day, it works, it lights up small stuff, the small size is my favoite feature.
Techincally your back-up light should be set-up with fresh batteries and only tested. That way you know it has good battery life should you need to count on it.
I've intentionally avoided rechargables. A light is one of those things that can get lost too easily and I prefer to limit the investment. With these lights it would take night dives beyond my wildest deams to make disposable battery cost an issue.
The Shockwave LED is good for 10 hours on HI and about 20 on LO. With 8 C sized Duracells for under $8.00 I come in at under 80 cents per dive.
