How we test

Guide to the table

Our test was carried out in an independent laboratory in New Zealand. Models were “warm white” 18-20Watt CFLs.

Overall score

  • Light output (40 percent)
  • Switching life (30 percent)
  • Warm-up time (30 percent)

Light output: Based on relative light output percentages.

Switching life: Calculated on the number of on/off cycles (up to a maximum of 6000) the bulb could withstand before it failed. A score of 10 = no failures.

Warm-up time: Based on how long it took for the bulbs to reach 90 percent of their maximum brightness.

Price is what we paid in January 2013. Prices are per bulb.
