in the second picture to the left the smaller white tube is the "lamp ignitor," it has three wires coming out of it, the second tube is a 1 M ohm, 1 watt resistor and the block is a metal halide ground ballast core rated at 250 watts and is labeled M 138/M153 with 120/208/240/277 V input. so basically all i need is an enclosed fixture. thanks for the input.
