Tear Down of the 2AA Defiant light - Question about driver

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

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 :slight_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.

Might Check Your HD Store, Mine had these for 7.76

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.

I’m sorry, but that is just ignorant and uncalled for! There are only 36 possible outcomes of a pair of dice!

Dude!

You just made me blow snot all over my leg!

That really is amazing!

Now try it with the disco strobe! Your next UFO flap in the making!

SOS gives the Auto-Exposure subroutine a full-lock workout!!

There goes the rest of MY Saturday!

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…

Edited to add pic:

Welcome to the forum g22dru and thanks for the update. Man, that is a total steal.

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…

Thanks ImA4Wheelr! Good to be here, great place!
Yeah, there were quite a few, thinking I should go back and get more…thought I’d check all the threads here first…take care

Here I fixed the pic for you

Oh WOW! now only $5.50! How did I miss that :smiley:

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!)

Just wondering if even worth it, but I have lots of extra parts lying around…
