Ultrafire Model?

[Tiresius]

What model is this light? I'm tempted to get it as a mod for my brother's hunting.

Ebay has several of these lights. They are called SA-9 from ebay. Look up item #181000989580, 181000989664, 150928099168 and 150928130292. The bezel is different on some of the lights but appear to be same besides that. There is also one brand GTL, that looks almost identical. Do a search for led flashlight and you should find all kinds of them on flea bay. But the one on G's list would be without the long shipping times from china.

I just picked it up today and am not too impressed with it. It uses an ez1000 emitter. The selector ring is integrated onto the bezel and I needed to put an o-ring to space them apart so the selector ring can move freely. Not sure if I want to use an XP-E or XP-G2 on it with my 3-mode driver @ 1.4a.

Am not happy with the current stock driver. Waiting to get more aluminum to mount onto a driver to replace this one. It's only 800mah on an XP-G2 emitter.

You could also add one or more amc7135's to the driver. Or you could try one of the intl-outdoor 2100ma AMC7135*6 5-Mode Circuit Board (Nanjg 105C). Should be a perfect match for the XP-G2 with choice of modes.

Since the last post was about adding chips, I have a question: can I add the 350 chips on top of the 380 safely?

Yes, the linear regulator regulates the current at 350ma coming from that chip only internally. The sum of all the chips is the max current it can provide.

I do not plan on adding additional chips to the driver. I need to fabricate an aluminum disc to mount the 16mm driver on since the original board is 24mm in diameter. It'll also play a role in looking cool :D

Light has now been modified. Here's the link but no beam shots as I am crappy with dark shots.

Thank you for the prompt answer.

I am going to avoid adding anymore amperage onto the light as the design has a poor heat transfer. It was only designed for an 800mah heat. At 1.4a, the slug that seats the emitter gets very hot in 1 minute of use. It stabilizes in 3 minute once screwed onto the rotating ring.

I would have thought with it's size it could have handled the heat fine but I dont own the light. And you said it had a poor design for heat transfer. I have a old C8 with a P7 at 3 amps and copes with the heat just fine. The SA 9 seems to have a better heat transfering body than my C8 so I guess it's poor design is in the pill.

If you are using windows, you can resize your images with paint before uploading to your host. I use photobucket for the host and its free. With Photobucket once uploaded you can resize the image there under edit, then adjustment, then resize.
