    Question LED's in Fog?

    I was at the local Police Supply store BS'ing with some of the folks that work in there.

    The discussion about Tac lights came up.

    There was debate about how well LED's work in Fog and rain.
    Some had the view that a regular light bulb beam worked well in fog, but others say that the LED's worked just as well.

    I haven't picked up anything tactical that is LED illuminated yet, so I was wondering if any of you have used LED Tac Lights in fog?

    Here in SW PA, we get a lot of fog, even when it hasn't rained much.

    I don't know about fog, but I know my SF L2 LED punches smoke significantly better than any of the non-smoke-cutter halogens (a la Survivor) I've used, mainly due to the color. I'd assume fog would be similar.

    I would assume the effect would be similar to using high beam automobile headlights in fog. The fog (water droplets)would reflect back the brighter LED light.

    I have not proved it to myself yet, but this has been discussed a lot over on the Candle Power Forums and the consensus seems to be that the incan lights work better in fog and rain than the led's do. I would tell you to go search it out there, but the forums have been down for a few days now. Not sure what is going on.

    I am trying to think whether color temp makes much difference - the LED output is in the bluer region whereas usually incandescents are toward the red end more.

    Always seems to me that whatever the light source - fog is a serious problem as the moisture mini-droplets give such diffusion and bounce back. When driving it sure is better to stay on low beam than have the full bounce back from high beam.

    Thats correct. The more blue light of the LED will scatter more in fog that they more yellowing light from and Incan. However, there are some LED that work well in fog or smoky conditions. For example, the Streamlight Propolymer 4AA Lux and Streamlight Survivor led. I've used both as a firefighter in smokey conditions and they work very well.
