flashlight/edc thread - Laser Pointer Forums

ossumguywill · 02-13-2010, 05:02 AM

Hey,
What flashlights does everyone here own? I have a fenix LD20, and I EDC a county comm maratac AAA. I'm not gonna post any of my cheap wal-mart lights with a bunch of 5mm leds or whatever, those hardly count in my mind. I figure if everyone here owns lasers, they might own a few flashlights.

Also feel free to post your EDC, I feel the two might be related.
On top of the maratac, I EDC my watch, phone, leatherman squirt, peanut lighter, DX mini universal remote, a single-handed folding knife, a small letter knife, my wallet, and some matches. Everything is kept either in the wallet or on a keychain besides the phone and larger knife.

UV flashlight? Can you actually light up anything non-fluorescent with it? It could sure be fun to have!

Tech_Junkie · 02-13-2010, 05:24 AM

Sure, its like a black light. You can still see everything, its just deep purple.

Cyparagon · 02-14-2010, 03:12 PM

I've got two P7-based lights from DX. one 1x18650 and one 2x18650 (significantly brighter). Also a 40-LED UV light that draws a total of ~5V*20mA*40=4W

Oh, and also a nice little cree 1W that takes one AA.

FireMyLaser · 02-14-2010, 03:44 PM

DealExtreme: $16.92 Ultrafire WF-502B 1W UV Flashlight with Clip (3.4V~8V Input)

Currently modified with a luxeon III white.

My friend just gave me a Gerber rx350 with a burned out bulb... I can stick a 5mm LED in the bulb holes, but it gives me like half a lumen... is this what happens when an LED "burns out"? I didn't use a resistor or anything, and it kind of seems like some LEDs flash really bright when I first put them in then go dim. I'll try it with a 33 ohm resistor later on.

FireMyLaser · 02-14-2010, 04:19 PM

How many volts does it get?

3-from a CR123. I'm using a red LED, so I figure a Vf of 2V. This means 1v/.03A = 33.33Ω. I think I have these equations right.... I might go higher so I can use lithium rechargeables.

FireMyLaser · 02-14-2010, 04:56 PM

Yeah that is correct. You're lucky not having it blow up, because it smells really bad.

hmm.... wtf. I might have to measure internal resistance of the light. Maybe it has a built in resistor... that might help explain the dim LEDs..... But do LEDs go dim if you overdrive them? If so, I've wasted like 5 LEDs. I also have a bunch of bright UV leds, but they like at least 5 volts.

will

EDIT:no internal resistance, IDKWTF is wrong. I'm gonna try and find an alternate head so I can install a (you guessed it) laser.

UV (black light) is very useful identifying traces of rodents. Their urine and feces glow. People have used them for years in warehouses, etc. to check for evidence of mice and rats.

Here in the southwest, they're used to find scorpions hiding, which also glow under UV.

They can get allot brighter, but only if you overdrive them to some point, then they will get dim and burn out within seconds. 1V overdrive is by FAR too much.

Alright.... then I might have damaged all those LEDs.

But I just found a spare bulb in an old headlamp that will tide me over for now... so now I have 3 decent lights!

God it took me forver to find out what edc meant (everyday carry, what you carry on you person, for the rest of you who are wondering).

I want one of those C bin P7's probably double 18650.

I usually EDC my phone and my wallet.

haha, Ive been having fun over at EDC forums and it's (I just realized that I use it's as a contraction of it has, not just it is. Mind=blow) inspired me to carry a bunch of crap in my pockets

I've actually managed to use every single thing in the last week.

iskor12 · 02-15-2010, 03:04 PM

Dereelight C2H>>>>>>it puts out 245 lumens (After the lens and reflector) and it's like the size of my pinky. LOL

C2H Cree XP-G R5 Flashlight

I Love this light.

FYI: Also a great company to buy from....flashlightconnection.com
No, I don't personally know the person who owns the site, however, I have bought through them enough times to know that their service is outstanding. They ship with in hours after you pay them and they are located in California. A++++

sweet! It reminds me of the MiNi 123, it's a ridiculously small CR or RCR123 light that puts out somewhere above 189 OTF lumens in a ridiculously small package.

I bought mine to check hotel rooms. Sheet stains, dirty bathrooms ect.

Cyparagon · 02-23-2010, 05:38 PM

You need a chemical to react with the proteins first.^

ColdStl · 02-23-2010, 05:47 PM

I took my DX uv light to a hotel with me once. I was able to see some stains on the sheets, just barely though.

Is a chemical required for the lower wavelength uv lights? (like ~380nm or below) I've seen a few for sale that are under $120 but have been reluctant to buy one yet.

ossumguywill · 02-23-2010, 05:56 PM

^I'm pretty sure, like Cyparagon said, you need a chemical that binds with proteins and becomes fluorescent. Blood and other stains are not fluorescent on their own-I've taken blood from a cut I got (at night, I scraped myself walking) and shined UV on it, nothing happened.

daveindelaware · 02-23-2010, 06:32 PM

My EDC?

Springfield Armory XD-9 service model, carried in a SERPA CQC Level II retension holster, w/ an extra Springfield Armory XD mag (either 10- or 16 rounds), for a total of 21 - 27 rounds of 147gr JHP personal defense ammunition... also a StreamLight Scorpion flashlight and a Spyderco Native folding knife.

It might seem like a lot (or overkill) to some to carry stuff like that, but doing so saved my life one day (vs. two armed robbers).

This thread reminds me that I need to make another ballistic nylon combo carrying case for my flashlight and spare mag....

ossumguywill · 02-23-2010, 07:04 PM

^overkill? Naw. The moment I turn 21 I'm getting my ccw (didn't anyone think that being able to drink and carry on the same day is a bad idea?), and I'll start practicing with a handgun when I turn 18. Although I sometimes think a spare mag is overkill. I'd be more than happy with 6+1 rounds in a PF9 or similar pocket carry pistol. I already carry a S&W folder. (my school is pretty well-armed for a high school

)

I confirm that said previously, however sometimes it is possible to see something on a very smooth and uniform surface without reagents. I use this bactericidal mini-bulb
