Retail Lighting Program

Efficiency Maine works with manufacturers and lighting retailers to reduce the prices of energy-efficient lighting products in stores statewide. In most stores, prices are simply marked down. In others, in-store coupons are available for use at the register.
 
Information on this page will help you compare bulb features, brightness and efficiency, color choices, shape choices, and bulb base choices.

** CFLs and LEDs require compatible dimmers.

Brightness and Efficiency

Because bulbs vary in their efficiency, it’s best to compare bulbs based on their light output (lumens) rather than their wattage (amount of energy used). The higher number of lumens, the brighter the light will be. Higher wattage bulbs use more energy. Here’s how bulbs compare.

Color Choices

Traditional incandescent bulbs emit a “warm” color. Today, bulbs are available in a range of colors:

Warm White, Soft White
The standard color
of incandescent bulbs
Cool White, Neutral, Bright White

Shape Choices

bulb-alineA-Line bulbs disperse light at a wide angle and are ideal for fixtures used to spread light throughout the room. A-line bulbs are a good choice for room area-lighting, reading lamps, and hallways.

Spotlights concentrate light in a small area to produce a bright spot of light. Spotlights are a good option for track lighting and overhead recessed lighting.

bulb-floodlightFloodlights cast a wider directional light than spotlights. Flood lights are ideal for recessed lighting, outdoor floodlights, landscape lighting, and motion sensors.

bulb-candleCandelabra bulbs imitate the shape of a candle and provide ambient and accent lighting. They are for use in decorative lighting fixtures, including wall sconces, decorative fixtures and chandeliers.

Bulb Base Choices
