Specs:
- tested to 300'+ ffw
- powered by 4x600ma Li-Ion AA size, 14-16V, approx $12 total
- 3W light emitter is automotive LED blinker similar or like this $12.70 - D1116A 3W 300-Lumen 14x5050 SMD LED Car White Light Bulb (Pair/DC 12V) - Car LED Light Bulbs, approx $7 per piece
- burn time while still having a good brightness is 5 hrs (it still burns forever after that and gets tester bored)
- twisting action power switch is magnetic reed operated from outside by magnet on a double loop of nylon line covered by 1.5 inch long bike innertube ring.
- sticklight is slightly positive in water column and easily clipped to ziptie or double ended clip to it body (container has a groove under neck)
- container comes from fitness drink $3 (swill tastes good too), make sure it is the cap with silicon film and not foil-sticker gasket (those will leak)
- almost 360 deg light output
- very durable heavy duty body
Purpose:
- flood stage video/photo light for wet conditions (cave). For photo scene you need 6-10 of them which create smooth spotless light.
- submersible marker stick light
- utility backup light while caving/sump diving
Deal-D0 light stick:

Guts, and triggering by magnet:
This and more DIY at Picasa (it might annoy you with registration - sorry google sux):

Example of use in caves:
Florida Caving - a set on Flickr
YouTube - D-Drop Cave, Lecanto, FL
If you heat up non-value CD, shape it as reflector while plastic is formable and stick this D-light in it - you could have a somewhat directional light pointed at some degree up without setting it on a tripod or anything.
Hopefully I entertained you today. Dive safe and have fun.
