Metal Halide Starting Issues
Metal Halide Starting Issues
(OP)
I have been at a lighting company not long and I have inherited a pending issue.
A 2000W metal halide fixture comes on when connected but when put off and even allowed to cool, it fails to come on.
My observations:
During initial start up, voltage across lamp sockets gradually builds from zero to 240v. But during times it fails to start, the voltage measured is about 400v.
Ballast specs: 2000w, 380v ( Lambada)
Capacitor: 50uF, 380v
Igniter: 2000W, 380v.
What could be possibly wrong?

This can also overheat the ballast so it shuts off. The usual troubleshooting procedure is to replace the bulb. However you may want to consider replacing the head with LEDs.

RE: Metal Halide Starting Issues
The fixture is fairly new. These problems happened just after installation.
What's the difference between a 2 terminal and 3 terminal igniter?
