Floodlamp power control

Posted on Feb 2, 2013

When setting up photographic floodlamps, it is sometimes desirable to operate the lamps at lower power levels until actually ready to take the photograph. The circuit allows the lamps to operate on half cycle power when the switch is open, and full power, when the switch is closed

The diodes D1 and D2 should have a 400 volt PI-V rating at 5 amps.
