This forum makes me so angry!

[KrameE]

Sometimes I think that discovering this forum was the worst thing that could have happened. I simply refuse to pay $900 for a single underwater video light when I know that they can be made better for cheaper and tt kills me that I don't have the tools or the skill to machine parts that I need to complete 95% of the builds discussed here on the board.

I know. These are first world problems.

So, in an attempt to build my own video non-canister dive light, I'd like to have someone verify a proof on concept.

I'd like to build two triple XML video dive lights using a mag conversion. (I think I want triple XML, I really don't have any...well...real experience with underwater lighting and maybe a single XML is what I really want. Please advise)

Soooooo, keep in mind that I will have to buy everything pre-made:

3D Maglite: $20
XML U@ : $8.99 x 3
H6Flex(?) Driver: $40
Hall Switch: $10
Britelumen Heatsink : $32
Maglite Dive Conversion Kit from 350xFire: $15

Materials (wire, solder, soldering iron, etc): ~$75?

Rough Guestimate: 2($140) + $75

Problems to overcome:
1-Machining the Mag Head down to fit the thicker lens
2-Sawing off the section of the mag with the clicky switch
3-Attaching remaining section of switch to head
4- Problems not thought of at this time

What am I missing and not thinking of, in this rough sketch?

Why only use the XML T6 and not the XML2? Color temperature?

Laps in memory. Thanks and corrected.

KrameE,
First off we all feel your pain. Many of us started off just like you, got totally obsessed and either decided the $900 light in fact had value, or spent a couple $K on equipment to prove otherwise ;-)

So your list is a good start but:
where's the can?
and the batteries?
Rather than use 3 XML singles, instead go with a PCB with them already wire from Cutter?
This will likely change you heat sync of choice.

There are other cheaper options... like TLSlights full build, I don't believe 360 is charging $900 ;-)

So you either do the designs and spend the money subbing them out... or get the tools and skills yourself.

I'd say spend the money and time to get the capabilities yourself, it's great fun.

As for problems 1-3, they've been thoroughly discussed on the forum before.

As for problem 4, how about shipping costs, batteries, Dremel tool (for problem 1), Hacksaw (for problem 2), JB Weld epoxy (problem 3).

And if you are thinking of making this a canister light, two cable glands, cable, PVC pipe for the canister, two latches, O-rings.

Oh, and a battery charger.

I would like to avoid the use of a can. I only need about 30-40 minutes of burn time. I am willing to accept the trade off.
I would like to use 18650 batteries, of which I already own 8...and they are easy enough to get.
I have looked at cutter, and very much like what I see, but I'm afraid of them because they seem a little too....easy. I have not read much from anyone here on the diving section using them for this purpose.
I also very much like TLSlights, but I would like to try and avoid a can. I have not spoken to them about an alternative, so shame on me for that part.

I own a dremel (I made an electric beer brewing vessel last year. Very helpful), can borrow a hacksaw, and have JB Weld laying around...I was hoping that JB Weld was a viable option, but seemed to easy to be true.
I hope to use the 18650 batteries I already own along with the charger. (DX Trustfire versions of both)
If I were forced into a can situation, I would probably just go to TLSlights.

I cam across this build http://www.candlepowerforums.com/vb/showthread.php?370700-Latest-build&highlight=fresnel+vs+ahorton

Maybe I will try this to get my feet wet.

Do you guys think it would be an easier first build?

I know it's the opposite of a video light, but I still want something to punch through the muck.
