Lighting Choices Demystified! From Our Friends at Efficiency Maine

Bulb Comparison Chart

You’d think it would be simple, but choosing a light bulb can be challenging because there are so many options at the store. This week, Efficiency Maine is providing information on how to choose a bulb and calculate lighting savings if you upgrade to a high-efficiency product.

The most common types of bulbs include incandescent, halogen, compact fluorescents (CFLs), and light-emitting diodes (LEDs). Here’s how the most common types of bulbs compare:

Choosing the right color or bulb color temperature is another key consideration. For example, most people prefer warm or soft white bulbs for living spaces and daylight bulbs for task lighting or reading. The chart below illustrates some popular uses of each bulb color:

Annual operating costs vary between bulb types and choosing energy efficient options can significantly reduce household lighting costs. Did you know that replacing an incandescent bulb with an LED can save, on average, over $5.00 a year per bulb? And many LEDs are rated for 20 years or more, reducing future replacement costs. The chart below compares the characteristics of halogens and LEDs and shows the savings possible when choosing the more efficient option.
