‘Long-Lasting’ Light Bulbs Not So Long-Lasting

If these light bulbs don’t last as long as advertised, shouldn’t the alarmists who worked to kill the incandescent redo their math and tell us what we’re really going to save? I won’t hold my breath, however. 

The Daily Mail:

Many energy-efficient LED light bulbs failed before their advertised lifespan, tests have found.

Some did not even reach the EU’s new minimum of 6,000 hours which comes into force in March.

LED bulbs from Ikea and Technical Consumer Products (TCP) performed worst, according to Which?

The consumer watchdog and European partners tested five samples of 46 types of bulb. New EU regulations say that from March 1, 90 per cent of any batch of LED (light emitting diode) bulbs should last at least 6,000 hours.

The bulbs were switched on for 165 minutes, then switched off for 15 minutes, in a continuous cycle until they failed.

Five types of bulb, some costing more than £10, stopped working before 6,000 hours in the majority of samples tested.

Another five failed before 10,000 hours for the majority of samples tested, despite claiming lifespans of at least 25,000 hours. In total, 66 of the 230 samples failed before 10,000 hours, though all claimed to last at least 15,000.

Bulbs from TCP and Ikea were the  only ones sold in the UK. Both companies said the types of bulbs tested have now been discontinued.
