XM-L T5

Flashlight Modding and DIY Parts
1

I got me a XM-L T5 from cutter , and since it was a T5 I put it into my Ultrafire A20 ...

Well , all I have to say is holly cow !!!!!

Its gone from 250L to over 600L , The beam shape / composition is almost exactly the same as the SSC P7 , so dont expect a spectacular thrower ...

My HS802 has a MC-E in it right now , when I get some T6's , I will do a transplant , [ HS-802 is a tight pencil thrower with XR-E emitters ]

BAck to the A20 , I left the original driver in place and just swapped in the emitter [ XML T5 ] , I havent measured current as yet , but I will do beamshots etc when it gets dark .

Here we go :

High / 1.77A / 620L

Med / .69 / 250L

Low / .25 / 100L

Beams after dark ....

Here you have a nice clean view of the XM-L T5 in the A20

And here is a picture of my A20 [ 1 x RCR123A ]

It's a lot of light! The group buy at CPF is finally gearing up and I'm wondering what I should ask for. Since I already have a drop-in, I'm thinking of just getting 1 T6 mounted to a 14mm board to build my own P60.

That's a huge jump in output. Maybe it is direct drive on High? Sounds like basically you've got a Quark MiNiX now.

3

Its a pocket rocket now , and gives my P60 [ 18650 ] SSC P7's a serious run for there money ....

T-6's have not arrived at Cutters as yet , they did have the T5 , so thats what I got ...

But looks like XM-L might be the go , though I dont know how well they will throw , yeah , those important beamshots ... [ tonight ]

I will compare to my SSC P7's ...

4

and it sounds more and more like the xm-l's are going to make a lot of other emitters second class. thank you to all of you for sharing your preliminary results.

5

OK , all my SSC P7 [ single 18650 ] are around 500L

The little A20 on a RCR123A blows them all away ...

EVEN the SST-50 [ mine did 500 ] is rubbish compared to the XML ........ Howzat !!!

I cant wait to get my hands on the T6 's and build some P60 drop ins [ RIP = SSc P7 / MC-E / SST-50 ]

6

though, for all out there that are far more expert than i am at this, will it be viable in a small, say 14500 or single 16340 host?

7

Did you get a chance to measure a tailcap current yet?

8

Updating original post as I go ....

Yes , Im sure you can use the XM-L with a 14500 or 16340 light [ I did ] .

Just cherry pick the driver you want to use , since I dont care about shortening the life of a RCR123A [ I have plenty of them ] , and I also usually dont run high , except to show off , and as can be seen , on low , its 100L . Damn , a 4 mode driver or ramping driver would be real nice [ for less than 100 Lumen output ]

Butt , 0.25A and 100L = I used to think 0.25A was OK for low , not anymore .

@old4570

Is this possible?

High / 1.77A / 620L

Med / .69 / 250L

Low / .25 / 100L

620 lumens with only 1,7Amps?

250 lumens with only 0,69Amps

100 lumens with only 0,25Amps?

10

Seems a bit overrated since there were reports of 600-700 lumens at 2,7A

11

Cree's documentation on the XM-L is 260 lumens at .7 amps for the T5 bin. 658 min flux at 1.77A to the emitter by those numbers.

12

ummmmm If this is possible I will transplant many of my lights to xml

13

If it does true 600LM at 1,8 its a real winner!

14

yep the forever substitute of the P7´s

15

And with better tint!

16

The current measurement is as measured : I cant measure current and light output at the same time [ Id need 3 hands ]

So it may not be entirely right , current may be slightly higher in use [ less MM ]

Unfortunately the A20 unscrews in the middle ... This is only as a guide , sorry , I dont expect it to be 100% , but just to give you an idea ...

Its getting dark now , Ive charged up some 18650's for my SSC P7's , so lets check out the beams ...

But yeah , a bad light for matching current to output , I should have some XM-L T6's in a day or two , so I will build some drop ins for my L2 Hosts

Then I can measure current and output at the same time ...

Beams shortly

620 LM form 1*16430 light.... The world just went bananas.....

Very nice mod!

Try this , beams as gif ....

Its cloudy , so way to much city lights [ reflected from clouds ] , so very bad conditions for beams , but hopefully you get an idea ...

19

That's a neat way of doing beam shots, but can you slow down the frame rate a bit? I don't have quite enough time to look at the picture *and* read the caption. Maybe 2 seconds per frame?

20

can post them right here one by one?
