An apprentice's mod... ultrafire f13/noctagon xml2 etc. - complete - but still need a beamshot?

I got a good cheap modding host from wallbuys for 12.88

 

The ultrafire F13.

http://cloud1.lbox.me/images/384x384/201305/ultrafire-f13-cree-xml-u2-3-mode-led-flashlight-1000lm-1x18650-black_pdchre1368779559193.jpg

 

http://wallbuys.com/Product/UltraFire-F13-CREE-XM-L-U2-1200LM-5-Mode-Whi...

 

Promising mod host as it will do 18650 and 26650. Has a nice LARGE pill and has a nice beefy feel to it.

 

This is what I had planned for this host.

UCL ~$2 from intl outdoor.

XML2U2 1A noctagon ~$8 from intl outdoor

Teflon coated 22ga wires

Solder fill the pill for better heatsinking.

I chose to go with a single mode direct drive (no driver!) for two reasons. First, because the last 2 drivers I have tried to install I end up butchering and breaking. What can I say... I have the gorilla fingers. Second, because I felt the host had sufficient mass and could take the heat of a 1 mode light without the need for a low mode to cool down. Oh... you want a low mode? Better use your keychain light boy!

Here are some photos from the mod. Good news - I didnt break anything and I got to use a blow torch!! FIRE!!!

Breakdown

My dad (blf member windup) behind the torch helping solder fill the pill (because taking a photo and handling a torch is difficult to do at the same time)

Lets cook up some solder!

Here is a shot of the pill before I drilled holes for the wires

Added copper braid to the tail cap (switch seems to be of decent quality) and prepared a contact board I had.

Mounted the noctagon xml2 and applied thermal paste.

Results:

It works! - I used a protected cell before using a 26650 imr just to be safe.

Silly me - I forgot that the XML2 has quite high VF and even direct drive on one imr 26650 pulls about 3.8-4amps MAX on a fresh cell. Still better than the stock 2amps and easily keeps up with a stock tiny monster (high mode vs high mode)...  it does handle heat quite well... I ran mine for 15 mins and it got warm but not piping hot.

 

not bad for ~$25 Smile and a fun afternoon.

 

Beamshots? I didnt take any since the Denver game was coming on tv and I didnt think it was much to see... maybe around 1200-1300 lumen? Im just glad I didnt break or blow up something hehe Smile

Would you mind keeping the wrong flashlight?

Sounds like a bad connection to me.

Nice one Paul!

About the flickering part, yeah it’s the most annoying this I face in many of my mods. My mods usually work but they often ended with slight flickering. |(

The F13 head diameter is smaller than a C8?

I dont have a c8 anymore but i think the lens was 37mm

i tightened the head down and the flickering went away and it got 10% brighter LOL.

sounds like a spring/contact issue

Good to know that your F13 is rocking now.

So the F13 head is really smaller than a C8. A standard C8 has 41~42mm lens.
