lightning210: Was just in Country Club & 360 freeway HD in Mesa tonight and they had a bunch right at the entry/return desk… Actually, all 3 lights were there. 2aa, 3c thrower, 5c. Hope this helps.

These where still 2 for $20 when I looked last week, haven’t been out since last Tuesday.

It threading into the sipik makes the light worth it Wink

I’m pretty sure both mine have next mode memory. I didn’t wait more than ten seconds between tries though.
I gifted one to a coworker but if it threads on to my sipik clone I may get a couple more and Frankenstein these some.

I don’t like the color difference between the hospot and spill. It’s minor but its very yellow around the edge of the hotspot

I’m glad I’m not the only flashlight collector out there, I was beginning to think I was strange.

Try taking out the emitter centering ring. It smoothed the transition from the hotspot to spill nicely in mine. I imagine the reflector coating conducts electricity. So you may want to lightly sand the bottom if you have any contact points (like the polarity marks) that it would rest on.

@lightning210 Did you go buy ALL the rest of the lights at the Mesa store??? I went in there today, thought I’d get me a couple more. There was a big box at the front there by the returns desk. Heh, the box was gone today and just 2 were left! I bought those…

I may give that a try, thanks 4wheeler

I took out the centering ring on mine as I got the same yellow around the hot spot and now it’s much nicer. Thanks ImA4Wheelr! Hard to get the reflector centered again while screwing it back down. I also tried it w/no reflector. It makes a very pretty little room flood Smile

Glad to hear it helped. You’re right about it being harder to center. The reflector has room to squirm around. It would probably be better to cut or file down the height of the centering ring. That would maintain the height of the reflector. Just not something I imagine I will get around to anytime soon.

Looks like those two 1R5 resistors are the sense resistors. They look to be wired in parallel, but can’t tell for sure. Probably does PWM for low mode.
How do I find out for sure. Is there a way to test?

Yes there is an amazingly simple way to tell if a light has PWM and it doesn’t involve wavig screw drivers or anything “dangerous” like that. Just uses your camera phone.

Hold the lens of the flashlight up to the lens of the camera phone and turn the light on, if you see lines across the screen like window blinds its PWM, no lines = no PWM. The reason for this is the frequency of the PWM conflicts with the cameras refresh rate (shutter speed). A cheap/old digital camera and/or a CCTV security camera should do it too. (Even works with iphone 4 & 5)

How about shining it at a computer’s fan?

That will work too. And I believe the slower the fan appears to spin, the lower the PWM.

That really is amazing!

Hello all, don’t think I’ve posted anything yet, just been reading and learning since my new obsession has begun.
Anyway, just wanted to share that these are down to 5.50 for a pack from 7.98 at my central Arkansas HD…

Aftrburnr, course I had to try this as soon as I got back to the truck and got NO light at all, no poof, no bright flash before death. Just nothing. Put the primaries back in and all was back to normal…(whew, didn’t kill this one!) Although, for 5.50 a pair (oh yeah), I thought Id take the chance…

Here I fixed the pic for you

Oh WOW! now only $5.50! How did I miss that Big Smile

I want to point out here that the sign says “was $7.98, now $5.50”
When you see a sign like this, it doesn’t necessarily mean that the higher was the original “list” price. In this case it was 7.98, but before that it was 11.98 and before that it was, I believe $14.00. Sometimes one has to know the value of something to appreciate how good of a deal a new, lower price really is. In this case it is a dchomak kind of price. If I were you, I would buy all they have.

BTW, welcome to the forum. We need more members like you!

Thanks for the picture fix, not sure why it did that…looked right before the upload. I’m on my phone to, so maybe that had something to do with it…Anyway, thanks for the warm welcome! I’m actually back at the store now for more! (Yes,I have a problem!-dont we all!)

Thanks for trying that but flat top cells won’t work unless you use a magnet. I may take my receipts to HD and have them price match themselves Cash If you have some button top 14500, try those.

Those were button tops, that’s all I have in 14500’s…good luck on the price match, I had to pick up a couple more at that price myself!

Was surprised I didn’t blow it like I did one of those energizer tacticals recently! Oops

I gotta figure out a better way to check, but I can’t help myself…what is the best way to verify being able to use 14500’s instead of AA’s? (When you don’t have the specs)

Sorry to ressurect an old thread but I thought id share what i found out.
I have these 2 defiant lights sitting in a drawer and collecting dust So i decided to open them up. I took out the pill and it dropped in just perfect into an ultrafire wf 602c host I have. With a 3.0v cr123 battery it seems brighter than the defiant with 2aa. Only problem is it gets pretty hot after a few minutes. Im happy with it now actually. I hope this helps someone resurrect an old light.

The original emitter is an XBD. I just recently upgraded one of these to an XP-G2 on Noctigon. I have always liked this light, but now with the upgrade it is even brighter and it also has a better tint. All I did was swap out the emitter and star

Actually after using it for several small uses, im hearing a high pitched sizzling noise as the light heats up. Seems to intensify when I shake it. I will discontinue use until I can open it up. Which bin did you use?
