The life of Compact Fluorescent Light bulbs could be shortened if they are not installed in the proper fixtures. Here are some points to consider for ensuring you get the most from your bulbs.
- CFL's that are Energy Star-labeled are guaranteed for a minimum of 2 years. If they burn out sooner, check with your retailer for an exchange.
- There are several grades of quality in CFL manufacturing. Basically, you pay for what you get. The cheaper CFL's will take a long time to warm up (to full brightness), and typically fail more often than others. The highest quality CFL's turn on instantly at near full brightness, just like an incandescent bulb, but they are not typically available in retail stores. Bulbs found in hardware and home building supply stores are a good buy, but make sure to use them in the right places.
- Don't use CFL's in any room where you turn the light on for less than 1 minute. (I.e bathroom, hallway, garage,) CFL's are designed to warm up and stay lit for longer periods. Interrupting this cycle can decrease the life of the bulb.
- CFL's should not be used with dimmer switches unless they are designed specifically for it. (these are less common and more expensive)
- There have been reports of bulbs in 6 or 10 packs, bought at warehouse clubs, having a higher failure rate. These stores sometimes get lower grade product in bulk.
- If you use a CFL in a socket outside your home, make sure it is designed for outdoor use. (these style will always take a while to warm up in cold weather)
