Compact Fluorescent Light Bulbs - CFL Lamps in Varying Sizes

While a "long life" bulb does last longer than a standard incandescent bulb, it still uses a lot of energy and it doesn't last as long as a Compact Fluorescent Lights (CFL). A long life 60-watt incandescent bulb usually lasts for 2,000 hours, but an equivalent 13-watt will last 6,000 hours or more, and use 75% less energy. ENERGY STAR qualified CFLs help you save money in energy and household costs and you won't have to buy and change bulbs as often.

Compact fluorescent light bulbs (or at least some kinds) do not put out their full brightness as soon as they are turned on. The bulbs I tested here happened to be in various fixtures in my house, and they take one to three minutes to warm up and produce full light output.

The test setup is simple. The bulb was off for over an hour, then I just started recording, flipped the switch on, and waited. Once the bulb reaches a steady brightness for a couple of minutes, I took that to be the max output. The camera was set to manual exposure, manual white balance, and manual focus. It was wintertime and the temperature in my basement was in the upper 60s. Compact fluorescent bulbs seem to take longer to reach full brightness in colder temperatures.

The bulbs tested here are:
1. Bright Effects 15W compact fluorescent floodlight
2. Maxlite 13W Home Comfort Series compact fluorescent bulb
3. GE 26W helical compact fluorescent bulb
4. GE 13W helical compact fluorescent bulb
5. Philips 65W incandescent floodlight (control)

The Bright Effects 15W floodlight is by far the worst of the bunch. The light output right after turning it on is probably less than 10% of the max brightness and it takes over three minutes for the thing to warm up and produce full output.
