Energy Saving Light Bulbs – Have You Gone Green?
Energy saving light bulbs produce high amounts of lumens (measurable light) from the small amounts of energy they drain. While the initial investment in energy efficient light bulbs is highly compared to traditional incandescent bulbs, lower costs on electricity in the long run offset the higher cost.
Since there is a shift towards lowering electricity use, and energy prices continue to rise, energy-saving light bulbs continue to rise in popularity.
Popular Energy-Saving Light Bulbs
Fluorescent / Compact Fluorescent Bulbs (CFLs)
CFLs generate light from the gasses stored inside the bulb, making them more efficient than traditional light bulbs. A fifteen watt fluorescent light bulb will generate approximately the same amount of light as a sixty watt incandescent light bulb. CFLs last considerably longer, and cost less to operate than incandescent lights. Because CFLs are compatible with older light fixtures, they are a popular choice for reducing energy costs in the home.
LED light bulbs are more expensive, however, they use approximately one-third of the energy required to operate compact fluorescent light bulbs. Another advantage is their ability to function in extremely cold temperatures. Also, while they produce a dimmer light, LED lights last up to ten times as long as CFLs. These energy efficient lights are more durable than other light bulbs because they do not contain a filament inside the bulb.
Ideal uses for energy efficient LED light bulbs:
• Task Lighting (reading, working at night outdoors)
• Landscape lighting to mark paths
• Indoor and outdoor Christmas lighting
Halogen Light Bulbs
Although not as cost effective as Fluorescent and LED lights, halogen light bulbs do provide benefits:
Durability – They are made of much stronger glass than traditional bulbs (this is necessary to control the interior environment).
Brighter Illumination – Halogen bulbs are one of the brightest light bulbs available because they burn very hot.
Dimmable – Halogen lights can be dimmed, allowing freedom to control illumination.
Variety – Halogens are available in a variety of shapes and sizes, making them the ideal bulb to use for track lighting, recessed lighting, landscape lighting, and security lighting.
Hours of Lighting – What to Expect
The following times are general estimates. Hours will vary, depending on the manufacturer, type, and style of light bulb.
• Incandescent light bulbs provide approximately 100 – 1,000 hours of light.
• Fluorescent lights (CFLs) last around 10,000 hours.
• LEDs can last up to 100,000 hours.
• Halogen bulbs can last anywhere between 3,000 to 6,000 hours.
