Quick Question about Princeton Tec Apex

Postby rbryant » Dec 7, 2007 11:58 am

Hi all..I will probably be doing several hours underground tommorow (5-6 hrs). I have used my Princeton Tec a couple of times, and I know it drains batteries fairly fast..so I will have plenty of batteries in reserve. Do I need to bring a spare bulb, and where would I order a spare?

The Princeton Tec Apex uses LEDs, not bulbs. as such, you don't need to worry about a spare - ever.

by the way, what setting are you using it on? on the "4 high" setting (the small flood LEDs on the sides), we typically get anywhere between 9 and 12 hours off a fully charged set of NIMH batteries.

in your case, for a 5-6 hour trip, you shouldn't need to bring more than an extra set, although of course it's always a good idea to have more than necessary (and you'll still need 2 alternate sources of light).

Thanks..i forgot it was a LED..whoops! I think you are right about the setting. I used the center light once and only go about 2-3 hours of battery time.

the center LED is useful for "whoa, look at that!" kind of stuff, but most people find it much too narrow (and much too power-hungry) for keeping on all the time. plus, you'll blind everybody in your party and no one will go caving with you anymore =)
