Default Underwater light (update)

I give credit to "snooze" for this idea and it works great.

Use a mason jar as your enclosure.
Drill a hole in the centre of the metal top
where your wire will go through. Use a 20 Watt
halogen bulb and if you wish add some coloured filter at the
bottom of the jar (where the light will shine through).
Silicone both sides of where the wire goes through
the hole on the metal top and attach the wire to the bulb
by any means (I soldered mine).

Wait at least 24 hours for the
silicone to dry. Before sealing the jar add some pebble rocks for
weight so the jar sinks to the bottom. Seal the jar up with the top and
ring. You can line the inside of the jar with aluminum foil to give the
light more direction.

Note: Use a DC wall adapter for power with 1 - 2 Amps output.
ie: 12 volts DC with a 20 watt bulb


Where did you get your adapter at? I might take a crack at one of these.

You could also use spray glue on the jar inner (masking the bottom) so the
aluminum foil stays put.

For tinting the bottom manually, pick up some Future Floor wax (google it,
to find multiple brand sources worldwide), and mix it 50/50 with walmart
apple barrel paint in your choice of colors. paint that on the inside of the
jar, although it let to cure properly, you could probably paint it on the
bottom of the outside of the jar, since Future is literally liquid polymer.

(Now ya gotta figure out some sort of adjustable stand for your mason jar
lamp.)
