I am looking at the Convoy M3 in 3000K for bad weather. I highly value my fellow BLFers opinions. Open to any flashlight under or at the 100 dollar mark. Thanks guys 
Newbie here. You must have thought of these points. But during a snow storm a warm tint penetrates much better than cool⌠cool can be blinding. And a high lumen light just reflects more and blinds us. Beam, not too much flood but not super narrow either. I took a photo and video with my phone last year during a snow, but I only copy & paste, no fancy photo account link stuff. Maybe I will break out a bunch of lights and experiment during the next fog or snow. But others have probably already done that. Let us know what you choose.
Definitely stay with a warm tint. Iâm a logger and most of my co-workers have changed to LED lights on their equipment.Unfortunately the most commonly available lights seem to always be in the 6000-6500k area.They buy them and the lights sure look brightâuntil we get into foggy or snowy or any kind of precipitation. Then all the brightness is reflected back and you canât see 20 feet in front of you. You have the right idea with 3000k.
Iâm in the process of acquiring parts for a mod for a âfoul-weather-throwerâ. Itâs going to be either a 2700, 3000, or 3500k SST20w running 5A in an ET G25C2 under a LEDIL IRIS (xpe2 version) Narrow TIR. Should hit 50kcd (with J5 bin 3500K) and yield a decently broad hotspot with minimal spill. I came up with the idea after I recently went out for an attempted photoshoot of my collection that Iâm mostly going to put up for sale. The heavy mist and shitty camera didnât allow this. Subjectively, to my eyes, and in a brown/winter season (no snow) landscape, the 3000k SST20 P60 performed very very well. My 4000K YooToo SD2 did okay, but the wider spill beam caused more foreground scatter. Despite being CW, the Cometa with a 5000K XPLHI did admirably well when zoomed in. Cool reflectored lights, especially ones with higher lumens and wider spill made seeing objects at a distance harder for my eyes, even if they did throw further technically. Iâm sure on a camera with fixed exposure settings and setup at some distance to the side of the light, it would be a different story.\
In conclusion, a small, warm-white zoomy would be my recommendation.
A narrow warm beam makes perfect sense. Growing up in Lake Tahoe flashlights where useless in snow storms because it just reflected of the snow as it was falling leaving me blind. Now I have a better understanding of what to look for. Thanks JaredM for the info. Your foul weather thrower would make a great BLF build that I would be interested in. Looking forward to see how it comes out.
Now to look for a beam profile of the Acebeam W30 in a temperature between 2700 3000K.
Are you looking for a purpose built thrower then? Since you first mentioned the M3, I figured you were going for a mixed beam with some breadth. I found the zoomy really a great setup since it casts a homogeneous beam tune-able for whatever distance and intensity of fog/mist you are experiencing. A fixed beam thrower locks you into a small range of conditions.
EDIT: I should clarify that my ET TIR mod is simply a BLF-sydrome episode. Itâs a light that I really like, but practically never use anymore. Itâs always sat in the grey area of too-large to pocket comfortably, but too small to really throw. This is an attempt at re-legitimizing it lol.
I am looking for a flashlight that does well in bad weather without casting light back. You mentioned a zoomy light which I have none. Can you recommend a warm zoomy that preforms well in heavy foul weather. If I could see 30 40 yards, which is pushing it, that would be better then 20 feet without a light. The Convoy was the first light I could think of that had a temperature of 3000K. I am open to any flashlight that will do the trick. My vehicle has 4 Hella yellow lights mounted on the bottom of the bumper and having the light lower to the ground really pushed my visibility out where I could see during bad snow storms while driving.
Nnnnooooonnnonono, nono. Zoomies are inherently âopenâ, and are hardly waterproof or stormproof.
Was gonna suggest a WW diving light like the SD02W. Made for murky waters, etc., magnetic switch, meant for diving (hence the name).
About as stormproof as youâll get.
Thanks Lightbringer, a diving light in a 3000K would work great. 
thanks Lb for catching that oversight. Thatâs what you call âtunnel visionâ haha.
It has me thinking of a solution thoughâŚ
Being that I always used my Cometa in full-flood mode like 99.65% of the time, I was also always toying with the idea of just putting some rtv in the âthreadsâ (not really, as theyâre just concentric rings) to seal the head from water/dust/dirt/etc. ingress.
As long as a good hard twist could dislodge it and let it be peeled out later if needed, it probably wouldâve done just that nicely.
Canât see why the opposite wouldnât work. Tweak the light to however zoomed you wanted (ie, go full Bat Signal and then back off a fractional-turn to get a decent spot), then seal it up.
