Do CFL bulbs have drawbacks that should be considered?
• Frequent on / off switching will shorten the life of these eco-friendly light bulbs. • CFL bulbs don’t tolerate higher temperatures well so using them in a fixture that traps heat will reduce their life. • The light output of CFLs will gradually dim over time. • Standard CFLs shouldn’t be used in fixtures controlled by a dimmer switch. • CFL bulbs contain mercury, a toxic substance, and must be recycled properly. If a CFL shatters, it should be cleaned up carefully. • CFL bulbs take time to warm up to full output. At normal room temperature, 30-45 seconds is about what to expect. The cooler the room though, the longer it will take. • CFL bulbs used outdoors in cold temperatures will not be as bright. • Screw-in dimmable CFL bulbs are available but their dimming performance is inferior to incandescent and halogen lamps. They have a reduced dimming range and may flicker and cut off at the low end.
