Sent some photos Jim,
but must have been over the Psub upload
limit.
Will put them on my projects page some
time.

With mine all you would see is a standard Mag-lite, except it's filled
with mineral oil.

Well done Brian,
reference to how much pressure your bulbs could
take, but it's packed away somewhere.
Modifying one of these existing
lights seems easier & cheaper.
The flash light I gave the link to, I was
intending for submarine use. If simply modified for
diving, the switch being a"push in" type would possibly turn itself on
under pressure or not be
able to be plunged if you got all the air
out.

Re: [PSUBS-MAILIST] instant dive light
Hi Alan,
Just got back from the harbor, succsess !! I dropped it down to
around 35' with the light on everything seemed fine. It was
difficult filling it totally with no air bubbles, I had one tiny
one. I may try to put some silicone on the O rings to keep any min
oil from leeking by. The next time I fill it I'm going to
do it in a min oil bath so I can submerge the entire light in the oil to
get all the air out. Those xenon bulbs are apparently pressurized,
not sure if that makes a difference. don't know how much pressure,
probably not much.
I would like to make an led light as well.

Hi Brian,
I got part way through making some LED dive
lights by modifying some $20- lights I bought off "Deal
Extreme".
900 lumen & free freight. They operate
off around 4 volts, so I'm going to link them in 3s to operate off 12
volts. They have O rings at every join
& are made of a fairly thick aluminum.
I cut the body down & pushed a hose fitting in the end, then
soldered in wiring & put on a tube, ready to oil
compensate. The LEDs in general take
tremendous pressure, I believe a similar oil compensated system went
down 10 kilometers.

[PSUBS-MAILIST] instant dive light
HI All,
I was pricing dive lights for the upcoming lobster season and was
floored by the outragous prices they charge for those things. So
I decided to take my 6 cell mag light, which has a xenon bulb in it,
and fill the entire thing full of mineral oil. The mag lights
have O rings at all the critical points of seperation of the different
segments of the light. I'm going to be dropping it down to 40'
today to see if the bulb can take the pressure. If not then I'll
most likely go to an LED mag light.
Brian
