As we vastly approach the change in seasons, we will begin to see the leaves change colors as they fall and blow around in the cooler air. We fall back in time giving us the shorter days and much longer nights. Therefore we depend more on artificial lighting to illuminate our Fall and Winter evenings.
Now, you may find yourself asking, “ Which home lighting option is right for me?” Here we have compiled some information to help answer that question and guide you through choosing the right option for your home.
Thomas Edison’s 1880 invention of the longer lasting filament has been lighting our homes for well over a century. Incandescent bulbs produce light by heating a filament wire to a high temperature using an electric current. The hot filament is protected from oxidation in the air by a glass bulb that is filled with inert gasses. However, these bulbs are very inefficient, only converting 5% of their energy into light.
- Initial Cost: $0.41
- Lifespan: About 2,000 hours
- Efficiency: Very inefficient releasing 95% of their energy as heat waste
Compact Fluorescent Lights (CFLs)
CFLs were introduced into the home lighting market as a more efficient alternative to incandescent bulbs. Compact Fluorescent Lights are gas discharged lamps that use electricity to excite mercury vapor. The excited mercury atoms produce short- wave ultraviolet light that then causes a phosphor to fluoresce producing visible light. CFLs convert only about 45% of their energy into light causing the remaining energy to become heat waste.
- Initial Cost: $4
- Lifespan: About 8,000 hours
- Efficiency: 3 to 4 times more efficient than incandescent bulbs
Light Emitting Diodes (LEDs)
Light Emitting Diodes are the newest home lighting solution on the market today. LEDs are a solid state lamp that uses light emitting diodes as the actual source of light. Many smaller LEDs are needed to replace the incandescent bulbs, but unlike both CFLs and incandescent lights, LEDs emit little to no energy loss as heat and are much more durable.
- Initial Cost: $16
- Lifespan: About 25,000 hours
- Efficiency: 2 to 3 times more efficient than CFLs and nearly 10 times more efficient than incandescent bulbs
