HID's Direct 'MTEC' bulb life?

[lee gsi]

I bought some 501's for my side lights and a pair of festoon ones for my numberplate light.

One of my number plate lights has blown already (Within 6 weeks).

Has anyone else had them blow within the year (They should be under warranty for 12 months I think)

I had some MTEC bulbs and i have had them in two cars now, about 3 years and there still going ok.
