Understanding Light Bulbs - CFLs vs LEDs

Understanding Light Bulbs - CFLs vs LEDs: "or nearly 23 years.

LEDs do not “burn out” like traditional bulbs and can reduce cooling costs since they emit very little heat, and heat is what wastes energy when you’re talking about lighting. This style of bulb is very durable, as it does not have a fragile shell or filament that may shatter, as happened frequently with conventional incandescent bulbs.


CFL BULBS

CFLs, or compact fluorescent light bulbs, are the tubular- and helical-shaped bulbs that use about 75 percent less energy than a traditional incandescent bulb. They are relatively inexpensive, though not as efficient in comparison to LEDs. Their lifespan is about nine years with normal usage and they can save you up to 75 percent on energy bills.

CFLs do contain a very tiny amount of mercury, about 4 milligrams per bulb, which is never released while the bulb is in use or intact. Your local waste collection agency can advise you on proper recycling of these bulbs.

HALOGEN BULBS

Halogen bulbs are another option to consider. They look and perform much like the conventional incandescent bulbs that are being phased out. Their energy savings and longevity does not compare to CFLs or LEDs, though they are still more efficient than the traditional option."
