Abstract
A lamp assembly for use with a rapid start metal halide bulb, and including a lamp head housing and a power supply source. The lamp head housing includes a circuit board with power supply contact surfaces, a high voltage resistant socket, a reflector, and an on-off switch. The circuit board provides an ignition voltage, an ignition voltage spike, and a supply voltage to the rapid start metal halide bulb. The power supply contact surfaces connect power to the circuit board. The high voltage resistant socket holds the rapid start metal halide bulb and is electrically coupled with the circuit board. The reflector is arranged relative to the high voltage resistant socket, and reflects light emitted from the rapid start metal halide bulb. The on-off switch is electrically coupled with the circuit board. The power supply source provides an AC or DC power supply and is adapted to be either mechanically coupled with the lamp head housing such that its contacts contact the power supply contact surfaces of the lamp head housing or wire connected to the lamp head housing.
