That's nice to know, since I lost my streamlight.

Let us know if that works or not.. If even worth to toss my Sufire away..

sure would be good cheap way to have a hunting flashlight.

That's not possible for $10. You'll tie up $6 for each of the batteries (#123) listed in the video. $2 for the flashlight, not sure of the amount for the light bulb.

Still not the cost of a Surefire or Streamlight......but definately not a $10 flashlight either.

Just my .02.

Well I just built mine today. You are correct in that it cost around $17 rather than $10 but dang....the little bugger is much much brighter than any other small flashlight I've ever used! I just wonder what the battery life will be with the crypton bulb? If it is least a comparable amount of time, then it is definitely worth it! This may just be the "NEW HOG HUNTING LIGHT" ;) to mount on your bow stabilizer, it is that bright!

123's can be had for under a buck apiece when bought in bulk online.

Ebay, for starters. YOu've got to look, but the deals are there. I'm at work, so much is blocked, I'll see if I can't find some this evening.

Edit: First hit on Google, "CR123 batteries" Try here (http://www.batteryjunction.com/crba.html?gclid=CK3XkunV1IwCFRlmWAod6WF8tQ)

I tried this setup today. I got the exact same bulb, flashlight body, and batteries shown on the video. The first time I turned it on it flashed once and then never again. I tried a second bulb and it did the same thing. Can someone tell me what I did wrong.:( :eek: :mad:

Did you make sure to use 9V bulbs?

massamino

The mod called for a krp 112 bulb, which is a 6v. Do they make a 9v bulb that will work? if so, is it a krypton that will fit the bulb housing?

If anyone else has had the same problems with the KRP 112 bulb blowing please post and let me know if you eventually had any success. I really don't want to waste my money on bulbs if they are going to fail.

mine worked with that bulb and 3 123 batteries?? as bright as a cheap Qbeam...

I went with a KPR 118 bulb. It is 7.2v the 112 is a 6v. I couldn't find any 9v. I think it will be ok since a regular 3v AA bulb is rated at 2.3v.

Dugie
06-18-2007, 10:20 AM
the 112 bulb worked twice for me, I am working on a 3rd with a pressure switch to mount on the bow, I'll post with pictures...any ideas on battery life yet??

The bulb puts off a lot of heat. Don't leave it on very long or you will melt the reflective/mirrored part that is made of plastic. Found this out while trying to find a leak in my attic. Guess that's why the Shurfire's are made of metal.

I was going to ask if it would work with an old Maglight AA 2 cell battery. I found out:

AA battery is 50.5 mm long, 14.5 mm diameter 1.5V
CR 123 battery is 34.5 mm long, 17 mm diamter 3V

So, 3 CR 123s is roughly the same length as 2 AAs (103.5 vs. 101mm), but the CR 123s are probably too large in diameter to fit in the aluminum tube. I'd have to get creative to make the Krypton tube fit too.

pressure switch worked...I'll try to post up pics...thought about shimming w/pvc a c cell flashlight...may work as well.

Went and got one of the 112 bulbs yesterday while on vacation and passing some time at the condo. It worked just fine and looks like I'll be making another one real soon.

For those of you that have made these, how are they working and how long do the batteries last?
Is it worth it?

Well, just put together the flashlight myself. I works like a champ and a hell of a lot brighter.

I would like to put together one with a pressure switch so DUGIE please post pictures and how you made it.

Westex

I did one last year that was really a bright little light. Only problem was that I used it while gutting a doe one evening and it got so hot that it melted the reflector.

BradC
09-10-2008, 09:39 PM
Is there a replacement reflector that you could put in when making this to take care of that problem?

09-15-2008, 11:22 AM
I would also know how to install a pressure switch in one of these.

jjff1019
09-15-2008, 10:52 PM
Well after using it for about 4 mins the bulb burned out. I was using the 7.2 volt bulb. If anyone has any suggestions please let me know.

Dugie
10-07-2008, 10:40 PM
remember it is a photo type battery, better in shorter burst...I have made 3 of these and finally found one that is a little tought and adjust the beam it cost probably 16 dollars total...

the pressure switch was bought at radio shack they have plenty of small ones to choose from...I broke open the old switch that was there (push button) then connected a wire out of the housing then to the switch. Keep in mind my light has a rubber cover or housing so it sealed to the wire so it looks like a wire running out from where the button was previously.

I try to get a picture and post it up....

I was thinking about making one of these tomorrow for a good flashlight for the lease anyway. i'm extremely interested in mounting it to the bow with a pressure switch, but i've got one question no one has addressed... will it just be a quick burst of white light? Is anyone trying to make a red filter? All of the expensive hog lights to buy all have red filters...

Love the creativeness though!

Centex,Maybe a red permanent marker will do. Color the lens red? Not sure just a thought.

You should be able to find a see-through red adhesive film at most any hardware or auto parts store. Often used for "fixing" busted tail lights.

Dugie

the reflector thing is still tough, the newest one I did has a thicker better reflector and it has yet to melt or warp, the garrity light above I did melt one of the ones I made. I have tried wrapping it in foil, works but hard to feep foil smooth and ruins the brightness.

these lights are great to have around and fun to make, but they do have limitations...as far as battery life, I get a good bit of use out of one set of batteries hard to say and hour or 2, I dunno probably the same as a regular AA flashlight. But again seems o last longer and perform better if used in shorter burst.

My reflector melted quickly, I turned it on for 30 minutes (like I would use it if I were to look for an animal) and it was melted. Fun to make but not worth it in my opinion.

You guys are wasting your time with these flashlight hacks. There are several LED lights on the market that are 150-200 lumens for the same money you are spending to hack this one and you don't have to worry about melting your reflector.

I bought one of the CREE 290 Lumen drop in modules for my Surefire M951 and OMG!!! :eek:

Hey how long do your batteries last with these high lumen lamps?

12-15-2008, 06:44 PM
I built the flashlight, 2 dollars for the bulb at radio shack, I had the cheap flashlight already, $6 dollars for the 3v batterys. It works just fine, brightest little flashlight I've ever had, batterys aren't cheap, so I only use it when I am tracking a deer I've shot.

Wow that is a very cool light! Its weird how you can make something so efficient for a lot less then the original cost!

With the 290 lumen LED I average about 4 hours of continuous run time.

That's not possible for $10. You'll tie up $6 for each of the batteries (#123) listed in the video. $2 for the flashlight, not sure of the amount for the light bulb.

Still not the cost of a Surefire or Streamlight......but definately not a $10 flashlight either.

Just my .02.

Greg

yeah but its still way less than 95 bucks

Not true, you can go to batteryjunction.com and get the CR123A for about 1.00 apiece. I have multiple highpower flashlights and this is the cheapest place on the web to buy parts and batteries. Also try putting an LED bulb kit in your shur fire. You can go from measly 85 lumens to 400 for only 19.00 bucks. Just change the bulb and your run time will increase 20 fold.

12-17-2009, 11:54 PM
I recently finished one of these lights. It cost a smooth 17ish bucks, and it's great. HOWEVER, MikeD is right about changing bulbs in existing lights and buying cheap. You can do the same thing for about $25, with a much better end result.

I actually made on of these last night. I'm going to do some predetor calling over the next couple evenings and thought one might come in handy. $1 little black and red flashlight from Walmart, $1.80 bulb from radio shack and about $15 worth of batteries (ouch) from Walmart. Inside the flashlight, there were four plastic ribs that held the AAs in place and kept the 123 from sliding in. I didn't have a big drill bit handy. So, improvising, I found the fat part of a 3/8" drive racket extension to be just enough larger the 123 battery to work. I heated the extension on my gas grill until it was hot enough to soften the plastic but not hot enough for a trip to the emergency room:) Then forced the extension down the length of the flashlight body. Batteries and bulb slipped right in. Works great, very bright. I'm curious to see how long it lasts. It's still a $1 flashlight with fancy batteries.

I have done this again since and found a rayovac light that has adjustable beam and it does not melt the reflector, I am assuming because of the extra space or heavier plastic.

I think I got it at Lowes but I have had it for awhile. Battery life is still somewhat limited(as compared to LED lights) but still if you use it in shorter burst it works great and is very bright. I'll try and get a pic up.

it is heavy duty I think it was around 8 maybe 10 bucks but it has lasted over a year, I carry it in my pack/truck all the time.
