How to Make Can Lights Green and Energy Efficient
Can lights, also known as recessed ceiling lights, offer a sleek, glare-free lighting option popular in modern homes. However, they can also be energy wasters if not properly fitted with the correct bulbs (lamps). Here’s how to maximize their efficiency and minimize energy consumption.
Why Standard Bulbs Don't Work
-
Avoid “A” Type Bulbs: Traditional “A” type bulbs waste energy in can lights because they distribute light in all directions, with much of it trapped inside the fixture.
-
Inefficient Light Distribution: These bulbs don’t direct light effectively out of the can, making them a poor choice for recessed lighting.
Energy-Efficient Lighting Options
-
Parabolic Aluminized Reflector (PAR) Lamps:
- These are spot or flood lamps designed to reflect and project light out of the can.
- PAR bulbs are an improvement over standard bulbs but still consume more energy than other options.
-
Parabolic Lamps:
- Feature a curved reflector that projects even more light out of the can, directing it into a smaller, concentrated pattern.
- This focuses the light, making it more effective for highlighting specific areas.
-
Compact Fluorescent Spotlights/Reflector Lamps:
- These are a “green” choice that offers significant energy savings.
- Energy Savings: They save approximately 75% in energy costs compared to incandescent bulbs.
- Longevity: They last much longer than incandescent bulbs, reducing the need for frequent replacements.
- Less Heat: They produce less heat, which can decrease air conditioning demands in warm climates, further saving energy.
Addressing Concerns About Fluorescent Lighting
- Improved Light Quality: Early fluorescent lamps had a reputation for harsh or unnatural light.
- Modern Fluorescent Lamps: Newer lamps, particularly “warm” color lamps or “color-corrected” lamps, provide a more pleasant and natural light.
Summary: Making Lights More Energy Efficient
Upgrade your can lights for greater energy efficiency:
- Replace standard “A” type bulbs with reflector lamps.
- Consider PAR lamps for focused light.
- Opt for compact fluorescent spotlights or reflector lamps for maximum energy savings and reduced heat output.
By choosing the right type of bulb, you can enjoy the benefits of recessed lighting while minimizing your carbon footprint and saving on energy bills.
