So I have to say there is some cool stuff on this site, and thank you for starting something like this. I am a flashlight noob and would like to tap into the community's expertise. I am a flight medic who does SAR type missions in the backcountry and was trying to find a good light to put in my flight vest. I was looking for nothing too cumbersome, light, easy to handle when gloved hands are wet, dependable, and durable. I was looking at Niteforce SRT5, because of the red and blue options with the light. Never really tried to look for blood on my pt's with a blue light before but could be interesting. Anyhow thanks to all that reply, and thanks again for having me here.
