1000W search light – now build a bat signal - Hack a Day

1000W search light – now build a bat signal

Forget flashlights, and leave those burning lasers at home, [Ben
Krasnow] built a search light using a 1000W xenon arc lamp. That box you
see on the side of the trash-can housing countains a starting circuit
that shoots 30 kilovolts through the xenon lamp to get it started but it
is separate from the power supply. [Ben] started experimenting with the
lamp back in April but recently finished the project by using the
inverter from an arc welder to get the 50 amps at 20 volts needed when
the lamp is on.

The insert on the left of the image above is an outdoor picture of the
beam. You can make out a tree at the bottom. Take a look at the video
after the break for a full walk-through of the circuitry and some test
footage of the finished product.
