Underwater Kinetics SL4 LED mod?

[terence8888]

Hi,

I'm a new here so please bear with me!

I've got my trusty UK SL4 dive light which is really quite long in the teeth. I'm thinking of putting an drop in LED light module. But I cannot find the right size one (approx 34mm diameter x 29mm height).


Any ideas? Thanks in advance!

Hi just google it there's posts somewhere in "scubaboard.com" or "scubatoys.com" talking about how to use a module from DX to upgrade the SL4.
For me I have a UK SL4 as well which I got from 'Cash Converters'- a pawn store in Australia for $7.5 . I'm going to upgrade it as well but right now don't have the time cus I'm preparing my exams. But what I'm going to do for the upgrade is first dremel the bottom of the aluminum reflector to cut it short and flat then fit a Q5 or SSC p4 on it actually I have both p7 and mc-e as well but I'm into free driving Q5 and SSC p4 should be enough for me. Then for the driver I'll use the 3.6-8.4v dual li-ion driver cus I'll use 2*18650 instead of 4 C cells. All the components are ready just wait untill I finish the exams then heading for the Whitsunday Islands to have some fun.

I did this on my Photon torpedo, but it should work for you.

I purchased a Drop in module for a surefire light with a Cree Q5 in it. (Really bright efficient LED). It came in the mail today, and I promptly tore it apart and stuffed it into my second hand Photon Torpedo. The same should work for anyone with a Scout, or UK SL4/SL6.
Here's the module I bought, (~$13)

The reflector threads onto the LED module, so it's actually somewhat focusable which is nice.
It's the same length as the original UK drop in that was in the PT, but it's quite a bit smaller in diameter.

So I took a piece of old Maglite I had laying around, and cut a ring out of it, then squished it and wrapped it with metal tape to get the right diameter. Make sure it's the same height as the old drop in's upper ring, or this won't work.

After that, flip the batteries in your light (the center post on the drop in is (+), opposite of the orignial) and screw the head on. Mine actually seats better with the drop in than it used to with the original. about 1/4 twist from bottoming out the light comes on.
I compared it with the Maglite brand drop in that I have in my old pelican backup, and with the original UK drop in it came with (Top is pelican, Left is the UK drop in, Right is the DX drop in)-

I like it. This is a really quick and easy (and Cheap!) way for people running halogen bulbs to upgrade, or people who just want a little more brightness out of their LED lights.
Here's the drop in I bought, cheap, but it took a while to get here -

Since I was in the mood (and I fried my primary the other day ale: ) I mad a quick soft goodman handle for it. Dove it Sunday, Worked well.

Someone tell me how to put photos from Picasa in the post.

Damn I have to transfer my photos from Picasa to Photobucket in order to post the photos here, never thought Picasa is that lame.

Just finish my first exam this afternoon I think I just nailed it, got some free time this afternoon and spend couple of hours on the phase one of my UK SL4 modding, check out what I've done.

I use a dremel and a filer to file down the bottom of the original reflector about 5mm I think and it takes me nearly half hour. For the heatsink which I'm particularly proud of, I made myself a C sized heatsink out of a 28mmx28mm heatsink which originally designed for video card heatsinking. I'm quite satisfied with the finished module though it takes me nearly 2 hours.

For the LED I've tried MC-E which fits perfectly, but I don't think I'm going to use that on the SL4 I'll probabaly go for Q2 or SSC p4.

I'm still waiting for the thermal glue from DX to make the LED module and I think I'm already half way through.
For the phase 2 I'm going to finish the electronic part of the torch, the driver as I mentioned before going to use a 8.4v driver which I already have, for the battery going to put a pair of 18650s into two pairs of these plastic C battery converters which also on the way from DX. I think for a ssc-p4 a pair of 18650s should last for a while. So if anyone interested in this keep an eye on the thread.
Last check out my awesome desk lamp.
