| I've got a couple of 160W Philips (Canadian origin) Self-Ballasted MV lamps running in outdoor "barn" lights. They're NOS, but after a while of use, they start to randomly cycle. One took 7-8 months, one took 1 month the other 3 weeks before acting up.
Anyone knows what could be the issue?
They're not burning out and the cycling is random, some nights will be constant ON / OFF / ON / OFF and other night steadily burning. Could the bimetallic strip be malfunctioning in these? Something is causing them to extinguish. I don't believe it's the sockets.

| Does the operating position match the lamp rating? They use to be sensitive on that.
Mainly when worn out.

| Hmmm there isn't any marking suggesting base up or down, but they're operating base up, which I think would be fine.

| What voltage are the lamps rated?
I don't know how well MV lamps tolerate over voltage, but a 127/220 volt system will have a higher nominal then a 120/208 volt system.

| Self-ballasted mercury lamps, are intended to operate in BU. Horizontal position, may cause them to cycle, and both horizontal and BD shorts their lifespan significantly.

| The filament of 160W SBMV lamps is the same single coiled design as the 500W, so I expects that the high wattage ones would also being limited to at least vertical burning position.

The burning positions quoted by manufacturers seems to vary on this. I have several which are definitely quoted as universal burning, but the Philips 160W ones I just bought quite clearly state on the packaging that they are vertical plus or minus 30 degrees, cap up OR down. |
