I've been looking at this little spotlight for a couple weeks now and today I picked one up. I am interested in the 4AA end of it. That's right down my alley.
Rated 500 meters, 100 lumens, 10 hours. It has a high and a low. Click it on once, it's high, click it on again, it's low.
It's a small light and that's another reason I like it. I have never favored the big and heavy spotlights. This one is small and light weight.
I have not measured the diameter of the lens and reflector. I will do that when I tear it down again, to mod it.
Here's the tail cap. It screws off. The inner contact plate is independent of the cap, so it can fit in and the cap can turn without turning the contact plate.
The batteries are in series.
Never heard of these.
First, remove the rubber cap off the lens
Remove two screws that hold the lens on, one on top and one on bottom of the lens holder.
Lens and holder. Yes it is a GLASS lens. I was wrong on the last one...
5 screws to take the body apart.
As you can see, the other reason I wanted to play with this light, is the large aluminum heat sink that it has. That whole housing is heat sink.
The trigger and switch.

Any idea what that screw adjusts? Voltage or more like Amperage?? Anyone?

Is that maybe an XP-C emitter in there? Sure is small.
I did a test of the amp draw
HIGH - That is awfully high for this emitter. 1.5a max? No wonder it's blue when I turn it on.
LOW
I did this test several times and repositioned my leads each time, in case I did not have them held on tight. The readings came out the same after 20 times of high and 20 times of low, so I think they are close to correct.
I did not do voltage. I will when I tear it back down again. Yes, I put it all back together, to do beam shots tonight.
I played with it in Wal-Mart and I played with it in the garage. It has a very TIGHT beam. It is going to throw well. I just haven't decided for sure yet, but I happen to have a Nichia from Craig, that I really want to put into this light.
EDIT: The lens measured 54.7mm and the overall OD of the reflector is 60mm, but the lens sits down into the reflector, so the usable diameter is 53mm. I still didn’t measure the depth.
The LED voltage measured 3.34vdc under load. High setting on LED.
That's all for now......... Beam shots tonight, well after midnight.

Well, it's complete. I used a Nichia 219 and made a copper plug for the heat sink. I am using the board as it is, since the Nichia will take 2000ma anyhow and I'm putting out around 1800ma, it should be fine.
Here's the photos:
Not pretty. but functional
I replaced the wires with teflon wire for everything except that stupid litle red led. It's all tucked away better than stock.
I found thermal grease in the bottom of the reflector and I also found several spots inside the reflector. Of course, you can never wash a reflector. They always seem to look worse afterwards, so I stippled it with clear. I do not like spotlights with a tiny spot and no spill. I have no use for them, so I'm not worried about having a bigger spot and a little spill, which is what I have now.
It works, it's done, beam shots tonight for comparison.
