Metal Halide Startup Problem

[Darkness]

Spent yesterday installing a 70w Metal Halide outside which was an awkward installation.

Anyhow, after all that work, the bloody thing switches on fine, but after 20 seconds or so, it goes out. If I go away can come back, it sometimes is back up running.

If it does go out and I switch it off, then back on again, it lights up again and then goes out of the 20 seconds etc. Sometimes it flickers when I switch it on.

Is this a faulty bulb or an electronic problem? Cheers.

most likely the lamp, thats assuming your using the correct lamp, is the glass ball bit within the lamp severely off colour
Is the lamp new and is it high frequency control gear

The light is new. I haven't went back up to check the light but will take a look tomorrow. I can't tell you the tech bit of the light but this is the light after a quick search.

Did you get the photocell option,
if its the old fashioned ballast and igniter type, it may be worth checking the fitting supply voltage, a low voltage can sometimes cause on/of cycling.
high frequency units have a wider tolerance

Its the non-photocell version.

The light is on its own circuit and the meter was showing 236v. I guess it would be better to test the voltage in the light fitting itself.

My local dealer stocks Ansell and every light I seem to get from that brand has problems switching on.
