I bought the Gerber Cornea today at REI to see if it would be a good choice as a utility light for my girlfriend. The specs on the packaging say:
18 lumens
water resistant
2AA batts
.7 watt Nichia Rigel led
Beam is adjustable from 83 to 230 feet.
Specs from the REI store computer said that it's regulated to about 7 hours. That was a main point in my purchase.
I've been playing with it and the beam is still mostly a spot with minimal spill beam. It does throw pretty well with a shift toward blue but not objectionable. The tail cap has a very sensitive tactical switch. I'm not sure how rugged the switch is. Definitely less pressure needed than my Inovas. I wasn't looking for a "blaster"-type light, just moderate illumination.
So far it seems like it may fit the bill. The "main squeeze" doesn't abuse lights so it probably will work for her.
