Minor problem I admit but has anyone got any ideas why my 8 year old fan oven has suddenly started eating bulbs like crazy. Costing me a fortune. Standard 15w ses high temp bulb, cover and seals all intact. Oven plugged into standard sso on 32A radial with nothing else on circuit. Original bulb lasted about 4 years. Recently had 4 bulbs in 5 months. Is it just a coincidence of me getting dodgy bulbs (tried different makes - Osram, GE, Tesco) or are sinister powers at work here.

 
maybe his bulbs needed a bit longer in the ground?
Should that not be Earth cause we don't use ground :^O ;)

............ and then the fight started!!!!

I know this may sound silly but did you actually test the lamps that you think have failed?

e.g. with a meter or in another fitting?

are you sure there is no problem with the actual contacts in the SES lamp holder in the oven,

i.e. you disturb it when unscrewing old bulb, makes batter contact for a while

then goes High Resistance again later, so light bulb appears to 'stop working'. ? :| ?:|

 
No there not. A luminaire is the fitting the light bulb fits in .Remember, Lamps glow, bulbs grow.
Lamps - glow,

bulbs - grow,

currents - flow,

fuses - blow,

touch voltage - low,

I type - slow!!!

:DBlushing:O

I'll go and sit back in the corner again! :|

The lamps are definitely blown - they're clear so easy to check visually.

Possibly just blowing to hide the fact the oven needs a bloody good clean:D
