4.80 AA light from Fast Tech

I am going to buy two, and if not good will exercise the eBay money back guarantee. I have 4 of the lights from Fast Tech. Probably will take a couple of months to get the lights.

Every thing came through OK. Glad I ordered them.

I just ordered two from the same seller; My plans are to swap the driver and add an XP-L emitter to make a pocket flame-thrower.

Ordered yesterday afternoon, already updated as "shipped" with a tracking number...

I have to stop I cant keep from buying cheap lights lately………….

I have probably ordered 15+ different lights since sometime in December……… the wifey is not going to be happy hopefully I get to the mail a lot more than she does.

Just ordered one from fasttech. It’s cheap enough that loss isn’t a big concern and I have some lithium primary aa’s that I can use in it rather than risking my rechargeables. Not sure I like the modes or mode memory however so that might mean a driver change eventually.

John.

jerm03, did you order the $2.99 ones off of Ebay? How do they compare to your others? Same Q5 led? Just as bright? Finally, was there any customs issues? They sure harp on it on their Ebay sales page.

Yes I bought two. I could not tell any difference in the others. There were no customs problems that I am aware of.

IIRC, this is the seller he used: Ebay

I ordered five of these and they were shipped on 1/31/15. It shipped next day as I ordered on the 30th. Looks like it took about a month for them to arrive for Jerry so I’ll anticipate about the same. He also has a thread on this light specifically, that’s how I found out about the $2.99 deal.
:slight_smile:

Edit: Jerry and I were posting at the same time :wink:

Thanks to both of you. Gonna order a few.

Here are my results of testing with various batteries. I like the light.

Optic replacement mod...

After upgrading driver and the emitter to your choice of XM-L:

Install this TIR: https://www.fasttech.com/products/1108201

...with this isolating disc to center https://www.fasttech.com/products/1581402

...along with a slightly thicker O-Ring to take up the extra space:

It turns out to be a perfect fit, and creates a great beam pattern. A decent driver and some high-current 14500s would make this into a crazy-bright pocket light. I installed a Nanjg 101AK; even @ 1.4A using my three-year-old TrustFire cells is very impressive.

Also, how about that annoying keychain nub on the base? No problem there... A dremel, a file, and wrapping up with some rubbing compound clears that up. Now it tailstands! Add a good thick layer of GITD nail polish and you get this:

Nicely done. I had just about given up tracking down a replacement reflector for this light, never thought about a TIR. Any chance of a beam shot?

I don't have the means for a GOOD beam shot, but this should at least give you an idea of the beam profile:

Nice smooth beam pattern, great mod!

Yes indeed, very nice. I’m thinking one of those lenses will be going on my next order. Thanks.

Great mod, i will order the part to see if i like it better than the stock reflector, do you think the TIR would fit an XP-L?

Can you guys help me out though, i totally failed in opening this light :frowning:

Am i supposed to screw out the driver to get access to the pill or what?
The driver looks glued in, or is the head able to screw open in to parts?
I can’t see any seam that would indicate that.

The head unscrews from the battery tube and also unscrews in half for access to the emitter. The driver is a simple press-in IIRC. The optic fits an XM-L so an XP-L should fit fine too. You'll probably want to use the XP centering ring instead though.

Thanks,

Did you buy yours from the ebay seller or fasttech? mine is from ebay.

I think mine is glued together :frowning: it really don’t want to open i can’t even pry the driver out, it already have scrapes all over because it just don’t want to budge.

I guess i will have test some intense heat on to see if it will loosen up the thread lock gunk, i hadn’t planned to use the driver or led anyway.

Nice that the optic will fit the XP-L (sorry i missed that you used a XM-L of course it will fit then :slight_smile: it was the fasttech description that threw me of) & good point about getting the correct XP centering ring.
I don’t have any extra o rings, where did you get yours that was slightly thicker O-Ring & a better fit.

Did you use a copper DTP mcpcb on this, i wonder if the optic+thicker o-ring is including the thicker mcpcb like a noctigon or sinkpad?

Applying intense heat worked :slight_smile: but i melted the reflector+led because i got it to hot :frowning: to bad, now i need that TIR & fasttech aren’t shipping because Chinese new year.

I managed to poked out the driver from led side, it probably was just pressfitted in but i just couldn’t get it moving from the battery side.
EDIT
I just realized that it was probably the wires from the star that held it in place, they where so short it would have been impossible to get it out of the head anyway.

I haven’t even any 14500 batteries anyway so i need to get those first before i can even do anything fun with this :slight_smile: but this is a really nice host now that get to look at all the part separately.

One potential problem i see could be there extremely tiny space for the driver…… i am not sure it is possible to fit a nice FET driver in there, i will have to make some closer measurement for that though.
