This MVR250/U multi vapor lamp lasted a whopping 6 months before cycling... switching back to mercury vapor lamps in this fixture! And yes cap and ballast test just fine! Bulb was operated in an open bottom reflector base up!

Ouch... what kind of fixture was this in?

Any machine is a smoke machine if you operate it wrong enough.

Yep GE MH lamps in this shape are junk. I think the current ones are pretty junky too. I've had MV lamps cycle at my house and I'm not sure why. Other lamps don't cycle on the same fixture and that same lamp doesn't cycle when put into another fixture. Just random incompatible pairs I guess. So far it's happened to one 100W MV 240V ballast (60s GE ballast with an 80s NOS GE lamp; same brand go figure lol) and currently the 175W MV lamp in my 100/175W M-250R1 cycles occasionally. I forget the make and era of the lamp though. It's either a 90s Philips or 2000s GE. I have to double-check the wiring of the fixture. Who knows, maybe I've got it wired for 100W accidentally. Looks about as bright as a 100W MV but it's a used lamp and seems to be the correct color.

Please check out my newly-updated website! McCann Lighting Company is where my street light collection is displayed in detail.

I've had no luck with "multi vapor " lamps at all. I use 400 watt probe start and 250 and a few 175s in probe start all seem to only last maybe a year to year and a half. No color shifting just all of a sudden continuous cycling.

This shape of lamp was meant for GE suspended can lights which standard ED lamps don't fit in.

Don't be fooLED, T8 IS the worst thing to do to a magnetic T12 fixture.

I’ve always wondered about this strange shape. “PD” maybe as it looks like a cross between a PS and an ED? I agree with streetlight98 on the ballast/bulb combinations, I too have found with many discharge lamps that some lamps and fixtures work together & some don’t, even if the ballast and lamp are technically correct matches. I have some 250w MH that will cycle if used horizontally but work fine vertically and they are universal burn lamps and quite new (no blackening).

Cycling happens if the arc voltage rises too close to the OCV of the gear...the arc current falls and the lamp extinguishes...then, rinse and repeat.

If I get HID that does this on my test rig, I simply raise the OCV with the Variac and "chase it up" maintaining the operating arc current and letting it find its own arc drop.
