Downlights test results table

 

Guide to the table
Our test was carried out at an independent laboratory in New Zealand and funded by the Electricity Commission. See About our test for details of what the downlight fitting ratings mean.

Extra room-heating required is the extra energy (lighting and heating) required to keep the test room at 20°C when downlights are used. It’s expressed as a percentage of the energy required when the room is fitted with a single bulb-holder and a 15W CFL bulb.
