Energy Efficient Lighting
Today, economical, environmental and resource issues force us to look at energy consumption much more critically. Incandescent literally means, “ to give off light as a result of being heated.” With standard light bulbs, typically only 10% of the energy consumed is converted into light, while 90% is given off as heat.
New technologies are available that improve on the light bulb in terms of reliability and energy savings. Although the initial price for these new, energy efficient products is higher than that of standard light bulbs, their cost-effectiveness is far superior in the long run.
When people understand just how much money and energy can be saved with compact fluorescents, they often replace regular bulbs that aren’t even burned out yet.
Light output of a lamp is measured in lumens; energy input to a lamp is measured in watts. The efficiency of a lamp is expressed as lumens per watt. In the Efficiency of Lamps chart, this number is listed for various lamps. High Pressure Sodium and Low Pressure Sodium lights are primarily used for security and street lighting.

Lamp Type and Power Lumens Per watt Lifetime in Hours
The types of energy efficient lighting available include but are not limited to, new design incandescent, quartz halogens, standard fluorescents, and compact fluorescents. 1 Star suggests the use of T8, 4 ft. fluorescent tube lighting for most indoor, industrial and commercial use due to the Lumens per watt and the lifetime in hours.
