For the last twelve months i have been writing the date on light bulbs when i replace them.
Average life is about 3 months at the moment.. 100 watt bulbs used to last for years back in the 60's.
Now they have the cheek to offer you bulbs that will last about six months for a premium price! not sure how you make a claim if they don't last that long.
Are there any industrial 100watt bulbs that last for a decent length of time, or are they all fluro's.
