Lil $4 1xAAA keychain light

Hello all,

FL110C Keychain Flashlight

The search and quest for the holy 1xAAA keychain light is never ending story. I got this light from ebay. A few pictures speak for the rest of the post.


Arc-AAA Stock vs Arc-AAA 26KCd vs FL110C

The light dimension is 14.33mm x 74.93mm or 0.564" x 2.950". The finish is good and thread runs smoothly. The switch is spring loaded uses twist on action. There's an o-ring at the end, should make it waterproof.

I managed to remove the circuit assembly without any damage without removing the bezel. The bezel seems to be press fitted like Inovas. I will try belyo's ice poppin method soon.

The circuit is very simple. 1 diode, 1 capacitor, 1 transistor, 1 inductor with two seperate windings. Current consumption of this light is 190mA @ 1.3volts, which translates to long runtime. I have not measure the LED current yet, will do it soon. Not exceeding bright. The output ranks a bit below a stock Arc-AAA. However it is still brighter than the early version of CMG Infinity. It wouldn't be hard to swap the LED to a 26KCd. I will post a picture of the circuit assembly next.

The $4 rate is ebay bid .I can get more of these but they are $5.6 a pop at 10 units. I am really tied up with my job at the moment so it's hard for me to organize a groupbuy. I will try to contact the ebay person to see if he's willing to ship to other countries. So it looks like ordering from the website is a good way. I am not working for them, I got the link from google.

hmm, min. order of 3000pcs... who does the group buy?

how much was it on ebay?

Modders, start your engines...

Yeah, can we slap a 26Kmcd LED into those?

I was just on the website and found out that you can order any amount as samples, albeit a little higher price. The good part about it is that shipping cost is included. I just ordered three at $5 a piece including shipping. They have a list of other items that might be of interest which can be ordered as samples with included shipping.

the lug keychain hole is a major improvement over the nuwai without lanyard hole. I'd want one.

Post updated above.

Nuwai will be a better choice IMHO it's much brighter.

I had just purchased one on ebay AU, Nine dollars all up including postage, about seven Us dollars

any opinions on build quality? how rough are the threads, does it actually seem to be reasonably watertight?

Read the second post again.

Damn, I must be blind...thanks /ubbthreads/images/graemlins/smile.gif

Any thought on whether they should be able to handle one of the Lithium AAA's at 1.7-1.8V?

I don't know I don't have a Lithium AAA.

I tested it with 2xAAA it wouldn't boost. At 1.85V it runs for a while then stop boosting. The transistor got warm. It will run stable at 1.80V max.

Ok I have told the ebay seller to list the item available for the US and other parts of the world. For some reason he doesn't trust me and he listed the item in bid mode rather than buy now. I'll try to convince him so he'll do the buynow.

I removed the original LED and pop in a 26KCd LED plus polished reflector. The circuit drives the LED at around ~25mAh. Overall it's doing on par with an Infinity ultra with a better throwing beam to my eyes.

Is there enough room for two N cells? And the circuit and LED of course.

From the description, it seems like the light uses a simple Satcure circuit (a.k.a. Joul Thief), which at the best gives off ~50% efficiency. It is no surprise that it takes 190mA and is still dimmer than a stock Arc AAA. However, for the $4 price, you are essentially just paying for the metal work. It is not a bad deal in this sense.
