Which Light Bulb is Right for Me?
Choosing the right light bulb is a balancing act between energy savings, comfort, durability, cost, and compatibility. Each area of a home or office will require different types of light and present different opportunities for savings. Use the chart and information on this page to pick the perfect light bulb for your lighting needs.

Incandescent Bulbs
Incandescent bulbs provide rich and warm light quality, excellent color rendering, and controllability, but are the least efficient.
CFL screw-in bulb
Screw-in CFL Bulbs
Screw-in CFL bulbs are energy efficient and have the longest life of all light bulbs. However, they provide less pleasing light, start up slowly, may flicker, and are not disposable because of their mercury content.
halogen bulb
Halogen Bulbs
Halogen bulbs, an efficient variety of incandescent lighting, are up to 30% more efficient than traditional incandescent bulbs. When dimmed by 30%, they offer many benefits of CFL and standard incandescent lights without the drawbacks.
General Rules
Use a halogen bulb with a dimmer where:
Light quality is important
You want energy savings with ambiance
You want to control the light with dimmers, timers, or sensors

Use a CFL bulb, possibly with a dimmer, where:
Light quality isn't important
There is no risk of children or animals breaking the bulb
You want maximum light with minimum energy consumption
You don't need sensors or timers

When selecting a light source you should consider the following:
