Firemcd - I don't have either and there are many others here that may be better able to advise you. But I will throw in my two-cents and I hope it helps. I love cops and firemen - you all deserve so much more than you get for what you do for us. My brother is a cop. Had friends who were firemen, and I was a CAP S&R pilot for a very short time. So I offer this:
1. As I said I don't know much about either of those. But a friend of mine dives and likes UK lights, as do many on these boards. In fact, he recently found a UK C8 Dive Light w/twin Xenon bulbs while diving off of Wildwood, NJ. It was 100 feet underwater sitting on a shipwreck. He estimates it was down there for a month, based on barnacle growth. He pushed the button and it lit right up! He cleaned off the barnacles and he says it looks like new. I would say that based on that - UK makes some darn durable lights!
2. Your lights will probably get wet, but they may also get exposed to heat. Will these molded rubber lights be taken into a fire where they may melt? That may be a consideration leaning towards an Aluminum-body light instead.
3. Color - This you will have to decide on your own. I told my brother the cop to stay away from black flashlights. I know cops and soldiers dig black, I am an Army-vet too! They look professional and all, but if you fumble it and drop it at night before you turn it on - right when you need it the most - you may not be able to find it wihtout borrowing another F/L! This happened to me while flying a Cessna across Alabama. I dropped a black Maglight in the cockpit b4 I could turn it on, so I couldn't fnd it and I REALLY needed to check my charts. So ths is interesting. I have no experience in a fire, so I am guessing that some areas are very well lit from the fire, but others are dark and shadowy - again I am guessing. So these lights that are black and yellow should be noticeable in light and dark situations if dropped before they are powered on. But maybe there are others that are more visible under your unique lighting situation if you have not thought of that.
Anyway, just thoughts. I hope they help. Be safe out there!
