Thanks to our friends at the US Department of Energy, we have an expanding resource for lighting and energy efficiency information. In general, there are three types of lighting available to consumers. These include incandescents, fluorescents, and LEDs. A comparison chart can be found here.

Incandescent Lighting

This is the most common type of lighting in homes today. It uses a filament to ignite in a gas tube (or bulb). There is the standard "A" type bulb that most people are familar with, along with Halofen technology and Xenon technology (mostly present in undercabinet lighting), and incandescent reflectors.

Standard "A" type - Halogen/Xenon - Reflector

Fluorescent Lighting

There are two basic types of fluorescent bulb. The straight tube and circline tube (which many people are familiar with in commercial settings) and the compact fluorescent bulb (found in many reisdential applications). Fluorescent technology has improved dramatically over the years and are now available in a variety of color temperatures.

Straight Tube/Circline Tube - CFL (Compact Fluorescent Light)

LED Lighting

LED lighting is available in diverse applications thanks to its small size, energy efficiency, directional nature, long life, and relatively low heat production. This technology is rapidly developing and changing.
