Assumes all incandescent lights (~75w) in high use household areas are replaced with 15w CFLs and used for approximately 3 hours / day. Cost and CO2 calculations in tables assume 3 hours use per day.
Change over 20/50 watt halogen downlights to 10 watt LED models. Electricity tariff (weighted average between Peak and Off Peak) is 28c/kWh. Lights are used an average of 3 hours per day.
Check light temperature for appropriate tone.
Use of dimmers to provide relevant control to living spaces such as bedrooms.
