Average nominal output of compact fluorescent lamps sold in New Zealand

Year ended March 2013–2018, watts


Efficiency: measure of energy used to produce 1 lumen of light.
Lumens: a measure of the total amount of visible light (to the human eye) from a lamp or light source. The higher the lumen rating the “brighter” the lamp will appear.
Watts: a unit of power.
Sales weighted: weighted average of the units' efficiency. This average is weighted proportionally to the sales of units.

Data calculation/treatment

Annual energy consumption is based on assumed yearly usage.
The average is sales-weighted, which means it depends on the energy efficiency of units that were actually sold.

About this dataset

Through the Equipment Energy Efficiency (E3) Programme, New Zealand and Australia develop common energy efficiency measures to regulate the energy performance of products in both countries.
Suppliers of products regulated under the E3 Programme provide Energy Efficiency and Conservation Authority with annual sales data for the period of 1 April to 31 March. This is used to help measure the shift in product efficiency over time and to calculate the energy savings to date from these improvements in energy efficiency.

Purpose of collection

The Equipment Energy Efficiency Programme is run by the Commonwealth state and territory and New Zealand governments working with industry to drive improvements in the energy efficiency of appliances and equipment to save households and businesses money on their energy bills reduce energy use and reduce emissions.

Method of collection/Data provider

The measures developed through the E3 Programme are minimum energy performance standards (MEPS) and the Energy Rating Label.
