Which? looked at a range of lamps including LED, CFL and halogen varieties. ‘This is the first time that we’ve tested a range of LEDs and the results are impressive,’ the magazine’s report said.
Ledon topped the list, scoring 87 per cent for both its 6W and 10W LED GLS bulbs. The report said the products represented value for money, were durable and offered good functionality such as immediate light when you flick on the switch.
Osram also scored highly in the LED category – scoring 83 per cent for its LED Star Classic A40 which costs more than £10 less than the Ledon lamp. ‘It should last more than 12,500 hours, equivalent to 12.5 years of use,’ said the report. ‘But there are higher-scoring LED bulbs that last longer – around 20–25 years.’
But the two lowest rated lamps on test were also LEDs. TCP’s 5W dimmable LED candle scored 63 per cent, losing points for its slow start-up, while Toshiba’s E-Core LED 8.4W lost marks for durability, scoring 65 per cent.
The top scoring CFL lamp was GE’s 12W Energy-Saving Spiral, which was praised for its brightness and durability. CFLs from Ikea and Philips also scored highly.
