cfl lamps blowing

[marksparks]

went to a customer today whose low energy lamps he just put in his pendant fittings were blowing after an hour or at most three hrs.
i inspected the pendant drops and they wernt to good so replaced the drop for new checked and connections in rose. voltage is 250v at lampholder tungsten lamps work fine but the cfl ones blew again in a couple of hrs they are rated at 220v-240v, could it be the extra 10v causing this problem?

250v is near the upper limit. It's the first case I've heard .

have seen CFL go bang before and scatter glass and powder on the floor, got nasties inside them, should be banned

 

[marksparks]

just been back and found they had a new supply put in to make it a tnc-s system rather than the old tt that was in, supply company sending engineer out now

Less than 1micro-gram of Mecury Amalgum per lamp... most older members will have considerably more than this in their mouths (milligrams) due to filled teeth... the health risks are largely overstated by the alarmist popular press. The only real risk is inhaling the short life radioactive sub-micrometre dust particles liberated during a breakage or in the clean-up afterwards

As above and it has been stated countless times that running a regular lamp emits more mercury into the local environment via electricity generation than that of the cfl

As well as other radioactive substances and other horrid stuff, I wonder if whoever made up the phrase 'clean coal' could ever say it with a straight face
