We all know that we should be making the switch from incandescent light bulbs to more energy efficient ones, but which ones should we choose? There are LED bulbs, compact fluorescent bulbs (CFL) and halogen bulbs. As far as giving up and sticking with incandescent bulbs? Well, soon you won’t be able to. The Energy Independence Security Act is getting rid of the old bulbs. Starting in January, 100-watt bulbs are no longer being manufactured, and other wattages will soon follow.
There are four things to consider when it comes to comparing lightbulbs. There are the cost, the lifespan of the bulb (which will also impact the cost), the benefits, and the drawbacks for each type of bulb. Knowing how the lightbulbs compare in each of these areas will help you make the right decision about which lightbulbs will work for you.
Cost
These are estimated costs, assuming that a bulb is left on for about three hours a day. Figures are according to Lowes.
A standard 100-watt incandescent bulb costs about $13.17 a year, while a 60-watt incandescent bulb costs about $7.90 per year.
A 60-watt LED bulb costs $1.58 per year. A 100-watt CFL costs $3.42 per year. A 100-watt halogen costs $9.48 per year.
Lifespan
The LED bulb will last for 25,000 hours. The CFL will last for 10,000 hours. The halogen will last for 1,000 hours.
Benefits
An added benefit of the LED bulb is that there are many options for using a dimmer switch. There is no mercury involved, an the long life means that they are good for hard to reach places.
The CFL produces low heat and offers many color options. It is the most cost effective of the bunch.
The halogen produces a very high quality of light, similar to that of an incandescent bulb.
Drawbacks
The LED is the priciest bulb to purchase (although it gives the best energy savings). The CFL contains harmful mercury that requires safe disposal. The halogen produces high heat, which can raise the temperature of the room and also be a possible fire or burn hazard.
