Uniquefire XP-G R5 Current Draw Test Results

[RedForest UK]

Well, I'm sat at home until 7.30 tonight listening to the football. So I decided I'd do something useful while I'm at it.

I will be testing the current draw of the DX single mode 'Uniquefire R5' 18650 light at regular intervals to see what regulation it has, or doesnt have, so here they are:

Start: 1.44A
5mins: 1.30A
15mins: 1.27A (1.20A-1.44A)
30mins: 1.14A (1.09A-1.21A)
45mins: 1.08A
1 hour: 1.03A (0.97A-1.09A)
1hr 15: 0.99A (0.93A-1.09A)
1hr 30: 1.02A (0.99A-1.05A)
1hr 45: 0.97A (0.88A-1.09A)
2hours: 0.86A (0.83A-0.89A)
2hrs 15: 0.92A
2hrs 30: 0.69A

At 2hrs 30mins the light was still putting out a very usable amount of light, about 200lumens by my estimation, but the cell was down to 3.6v and I didnt want to over-discharge it so that's where I ended the test.

Results in brackets represent variation from the general draw shown on my multimeter if it isnt constant.
The cell I was using was a Trustfire 'True Capacity' 2400mah 18650 from DX, the ones with the black and red fire colours and silver writing.

The fluctuations you see in the current draw are very similar to what I see when testing sku 32953 (XP-G "R5" drop-in).

RF,

Thanks for your test.

First, I'm assuming this is a single mode drop-in.

During your test did you notice any significant drop off in light output?

You stopped the test at 1:15. Does this mean the light dropped out on regulation or you decided to end the test at that point?

Finally, exactly which UniqueFire light are you testing? Is this the Seraph SP-6 look-alike or the SF P6 L2 clone?

Thanks again for your test.

He's running the test now and is updating post #1 every 15 minutes.

1:30 results are now posted.

Yep, thats right, the match is over but i'm going to stick it out until the 18650 dies. My blue trustfire 2500's only last 1hr 10mins and 1hr 40mins respectively, and im now on 1hr 56mins with the black and red so it's looking good so far, from the cells perspective anyway. :thumbsup:

In response to the questions:

This is the Seraph body clone although I assume that it is simply a host for the same one mode xp-g driver sold separately on DX, although there does appear to be some variation between samples in regard to current draw. Also, there was no significant drop in output to my eyes from the start, although comparing the hotspot to my tk20's it did seem to have dimmed a little by the 45minute mark.

What colour is the circuit board for the drop-in? green or red?

your Trustfire 2400's are outlasting your Trustfire 2500's?

What regulation? It is direct draw. Btw, the correct name is UniqueFire R5 XPG-R4.

RF,

Sorry, didn't realize you had a "real time" test going....

BTW, who won the match?

 

[gcbryan]

What regulation? It is direct draw. Btw, the correct name is UniqueFire R5 XPG-R4.

So when it says it's drawing 1A they mean that there is a resistor to make sure it's not drawing more than that as opposed to direct drive when wouldn't be possible with a XP-G and a 18650? So, no constant current driver?

(Mine should have been here by now but apparently the USPS returned it to DX for some reason from the other side of the country from their sorting facility)!

No idea if it's a resistor or not, but if it was constant current to the LED then the current draw from the 18650 cell would increase as the voltage drops.

 

[Bullzeyebill]

Might have a voltage regulated driver. Gene Malkoff uses one in his M30.

so my big question is if this r5 is worth it to upgrade my R2 module in my L2..any chance you have both drop-ins for a side by side beam test? thanks

Yes, every time these red and black trustfires have been rated 'True Capacity' and seem to consistently outperform any other budget 18650 cells. I was still surprised by the massive difference in runtime shown in this test, the Blue 2500's only give me about 1hr 40 at best before dying completely, the Red and Black 2400's were down to 3.6v but still running after 2hrs 30mins.

Also, yes the name is technically Uniquefire R5 XP-G R4 but everyone ive heard of getting them has recieved an R5 labelled led pill so i figured i might as well call it just an R5 or it starts to get confusing.

We won the game btw :twothumbs just 1-0 against the bottom side in the league but we're now 11 wins in a row at home!

What is the complete text on the drop-in? The pictures on DX shows no label.

 

[RedForest UK]

The text on the module says 'Super Bright R5'. I've also tested it again on the blue 2500's and got 1hour 30mins before i stopped, the cell was down to 3.54v.

I just received this light and would like to take the front lens out. Does anyone know how this is held in place?

I took the head off but the glass doesn't just pop out from the inside as it would seem. I also can't tell if there are any o-rings sealing the glass lens.

 

[Painkiller1009]

I received this light today....wowzer
Very bright. Very nice
It rivals my MTE P7, if the uniquefire had a big reflecore like the MTE it would probably beat it.
Very nice if you are looking to pick up a cheap R5/P60 host.
Money well spent:thumbsup:

From the looks of it just unscrew the stainless steel bezel at the top to remove the glass.
Why are you wanting to remove it? Aspheric lens?

 

[Painkiller1009]

Opps I have the Uniquefire L2 xpg-R5.
Still probably the same drop in though.
