In areas where light is needed immediately, CFL’s may take too long to reach full brightness. The style takes a little getting used to, but the light it emits is just fine. Getting 60 watts of light for only 13 watts of power is a plus in my book. By using these bulbs in my home, I’ve shaved about $35.00 off of my electric bill. This is close to what they estimate the average homeowner will save. It all depends on how many lights are used in a home and for how long. The initial cost will range from $2.00 to $3.00 for each bulb, depending on the size and manufacturer. With a life expectancy of eight times the 60 watt incandescent bulb, the cost would actually be cheaper to buy the CFL.
Be very careful with these bulbs! They do contain mercury and can be very dangerous if broken. Read all warning labels and know what to do if this happens before installing one. I have had a few burn out within the first two months, but they are in my ceiling fan. This could be due to vibration from the fan. All in all, I’d have to say I’ve been happy with the bulbs so far.
