Flashlight Batteries: Replacing CR123s With 16340s (Part 2)
Last time, I damaged my LED drop-in module because it was rated only for up to two CR123 cells (6V). Two 16340 cells is already 8.4V. Now, I take a closer look at the damaged LED drop-in module and replaced it with a module rated for not just two but three 16340 cells. and that did the trick!
Flashlight Batteries: Replacing CR123s With 16340s
I see if it’s possible to replace CR123 (3.2V) lithium batteries with 16340 lithium-ion batteries (4.2V) on a SureFire G2 Nitrolon with an LED module. Do not try this on a halogen module!
SureFire G2 Nitrolon LED Upgrade
Princeton Tec Impact XL
The Impact XL is an underwater flashlight that can also be used for above-water outdoor activities or, if you prefer, an above-water flashlight that can also be used for underwater activities. Per manufacturer specifications, it is waterproof up to 100m. It has a single Luxeon LED bulb which can throw 170 lumens of light as far as 50m. 4 AA batteries provide burn-time of up to 50 hours. Its tough plastic body is clad in molded rubber for grip as well as additional protection. A lanyard loop at the tail end allows for the attachment of a lanyard, wrist strap, or clip. The switch is a rotating bezel. It has enough rotations to minimize the chance of opening and flooding the batteries while underwater. However, you turn it in to activate so there’s a chance, albeit pretty small, that a push, say from water pressure, will move the head in and activate. Other than that, I’ve no real complaint about this light. Highly recommended.
