Replace Incandescent Lighting in Kitchens and Bathrooms with Fluorescent Lighting
Replace incandescent lighting in kitchens and bathrooms with fluorescent lighting.
Kitchen and bathrooms in rental units.
- More efficient lighting – fluorescent fixtures produce four to five times as much light for the same power input.
- Longer life span – fluorescent fixtures last up to 20 times longer than incandescent lighting.
- Significant energy savings.
- Improved lighting quality.
- Reduced maintenance costs associated with bulb replacement.
- This measure can be performed during suite renovations.
- Payback is more favourable in family or full-time seniors' housing where lights are used for longer periods.
- Payback will be to the tenants in buildings where electricity is metered and billed for each apartment.
- Bulbs should be cleaned annually, especially in kitchen applications.
- Installations must meet all electrical code requirements for mounting and supporting fixtures and for electrical wiring and grounding.
- Specify 3500 Kelvin fluorescent lamps in either T12 (1 1/2-inch) or T8 (1-inch) diameters.
- Ensure matching ballast is supplied.
- Compact fluorescent screw-in type lamps can be used to replace most incandescent bulbs in existing fixtures.
- Fluorescent fixtures using T12 or T8 lamps in 12-, 24-, 36-, or 48-inch lengths can be used to replace ceiling and under-cabinet fixtures.
- Some incandescent fixtures may be rated for 60W maximum and be over-lamped with 100 or 150W lamps. This could lead to maintenance problems and present safety hazards.
Results in savings can be influenced by:
- Cost of electricity.
- Type of electric utility rate structure.
- Initial and final number of operating hours.
- Initial and final connected lighting.
Replace 100W incandescent ceiling mounted fixture in kitchen with one 34W T12 lamp + one vanity fixture with two 40W lamps in bathroom with one 20W fluorescent lamp.
Estimated installation cost - $83
Calculation of savings:
Watts (incandescent) – Watts (fluorescent) X hrs. of use/day X 365 days/yr. X $0.08/kWh/1000W/kW
[(100W – 46W) + (80W – 24W)] X 8 X 365 X $0.08/1000
Savings = $25.70
Simple payback – 3.2 years
