What to Look For When Purchasing Compact Fluorescents (CFL)
- Decide where you'll use them. A good place to start is a fixture left on at least three hours daily.
- Will they fit? Choose a lamp that is similar is size.
- Purchase Energy Star compliant CFLs:
- Circline or 2D styles are usually best for most table lamps. These also tend to be the brightest options.
- Match lumens to the incandescent being replaced. To compare lumens and watts see chart below.

- Choose the Color Temperature, if listed, that’s right for you; for example:
◦ Approx. 2700K = Warm White (looks just like incandescent!)
◦ Approx. 5000K = Cool White (White/Blue, often higher CRI)
- Does your chosen fixture have a dimmer switch? If so, be sure your CFL choice is labeled “Dimmable”.
- Avoid using CFl’s with photocells unless the control is specifically labeled “Compatible with CFL’s”. Timers are an easier option.
CFL’s contain trace amounts of mercury and should be disposed properly.
