In today’s technology era, sustainable, green, and energy-efficient are the new trends. Green lighting technology allows homeowners, business owners, designers, and trade professionals to enjoy great energy and cost savings. At Wolfers Lighting, we evaluate the many different types of lighting and light bulbs available to the eco-conscious consumer.
Incandescent Light: This type of lighting is the most commonly used electric light source in the home, due to its affordability and its availability in a wide range of sizes, configurations, and wattages. Unfortunately, incandescent light bulbs are an inefficient light source. Since these bulbs produce light by heating a solid material until it glows, most of the energy they consume is given off as heat, resulting in low LPW (lumens per watt) performance.
Halogen Bulbs: Tungsten halogen lamps are a refinement of incandescent technology and are a more energy-efficient home lighting option. Halogens save up to 20% in energy consumption and offer a longer service life and improved light quality. Due to the halogen gas inside the lamp, the evaporated tungsten is re-deposited on the filament rather than on the light bulb’s walls, slowing the bulb’s deterioration and improving lumen maintenance.
Fluorescent Lights: Fluorescents are the foundation for saving energy. These lights do not lose energy through heat emission and they convert more energy into visible light, causing them to be six times more efficient and last 20 times longer than standard incandescent bulbs. Fluorescent lights are available in a wide spectrum of colors, with warm white tones closely duplicating the color of incandescent lamps.
Compact Fluorescent Lights: CFLs use 75% less energy than standard incandescent lights and last 10 times longer. One CFL will pay for itself in just six months and will save about $35 over its lifetime. Compact fluorescent lights save energy in both indoor and outdoor lighting schemes, as they produce about 75% less heat, are safer to operate and cut home cooling costs.
Ceramic Metal Halide: This high-intensity discharge (HID) light provides more light (lumens) per watt than any other light source, as it closely resembles natural sunlight and typically is used for outdoor lighting. Not only is it more efficient than both incandescent lighting and fluorescent lighting, but also the average life of a ceramic metal halide is more than 10 times longer than an incandescent light bulb.
LED Lights: Light emitting diodes (LEDs) are green technology’s newest and most efficient light source. For more on LEDs, download one of our free LED Buying Guides.
