Review: E1320 Modified UltraFire/UniqueFire UF-2100

another thorough review by foy :beer:
im glad i didnt opt for the 3.5a one. my 2.8a gets too hot to comfortably hold after 2 minutes. would it be worth trying to pot the driver to add some mass? the soldering holding the driver together came off on one of mine anyway and i noticed it was really empty inside so i figure adding a few grams wouldnt hurt right?

i too noticed the green ring on my uniquefire also but its negligible when youre outside using it.

anyway thanks again erik. great groupbuy deal on a great light.

I noticed on the first batch I made after I sent them out that I didn’t add enough Flux and some of the solder joints came loose because of the extreme heat after extended use on turbo mode. If you want to send it back I will fix it for free and pot it if you want. There really is no way a light this small is going to handle that many amps regardless of how much Fujik I pack into the pill. That’s why it has a reasonable 1.4 amp high, the turbo mode is just for short bursts only.

Yep.

Like I said, that's the beauty of this UI. The light puts out something around 500 lumens on high. I ran mine last night on high for 1:45 non-stop, with no heat issues at all. That extra couple of hundred lumens on turbo is there when you need it and it will run for 2 or 3 minutes with no problem at all.

Great review, great light. Thanks to both of you!

I think I need another 2100 for modding it my self. Thank you Foy for the great review and E1320 for the idea, to mod this flashlight :slight_smile:

The drivers are ordered a few days ago and now I have to wait.

Great review FOY !

So glad I picked up on this DEAL.

One of the neatest lamps I’ve acquired.

Kudos to Erik.

ANOTHER Fantastic Review Foy, Very Nice Photos and Technical information.

Eric, there has been increased interest since your mod, Will there be a SECOND Round for this UF-2100 with modifications?

Triple A

I have the normal un-E1320 modified uniquefire. It draws 2.8a and gets too hot after 5 minutes or so on high. This looks like the perfect solution for this light. Great review Foy and nice work E1320.

Sweet light! Thanks so much for the review, Foy, and a huge thanks to E1320 for having made this. What an incredible exclusive perk for BLF members.

Frontpage’d and Sticky’d.

Awesome group buy and awesome light. Thanks to Foy for the review and to Erik for putting together a quality light.

I love how your cats always seem to be hanging around when you take photo’s. They love all the attention they get on BLF :stuck_out_tongue:

Come on, I read around 3A with IMR cell with stock 3-mode from DD deal for 9,85 USD.

It has nice heavy pill, but still too small to run on hi for more like minute or so.

Booo. I knew I was going to regret not getting in on this deal.

Great review Foy. Everyone who got in on this deal should consider themselves lucky(smart).

Is this an “off the shelf” 105c, or is the driver itself customised?

It is customised, you can also order the bare driver from him, just PM him

It is a 105C driver that has been reprogrammed by Erik with 5 brightness modes from moon up thru 2.8 Amp or up to 3.5 amp with extra current regulators installed. No strobe or SOS.

Thats exactly what I wanted to say about this light Foy. You are such a mind reader! Great review as usuall

I have the same opinion of the OP reflectored Ultrafire its a absolute wall of light and basically its all a hot spot! I definately dont own anything similar to this light. I am so very pleased with this light and its my walk around the yard light.

Thanks for the review and putting the words in my head on paper.

Thanks for the work that you did E and for the care package.

I would love to have a llight this size with the same beam pattern in a AA/14500 package.

And of course, thanks to Erik for these BLF exclusive custom torches!

Erik can make you one .

The one he made for me is the reason I didn't get in on this group buy .

And believe me , a 14500 size light pushing 3.5A into a 3C tint XML is totally awesome .

Edit : YEEEEHAAAH !

Yes I am going to do another group buy deal with the AA/14500 host once I get caught up with all my backed up drop in orders. I will start a new thread next week.

Since I missed out on the 18650 version, I will definately pick up the 14500 light.

Could we get them in neutral?

that would be a dream light.

thanks e1320 for what seem like awesome lights.
