In The Dark About Picking A Light Bulb? This FAQ Can Help
Purchasing a light bulb used to be straightforward. The switch to more energy-efficient lighting requires picking from a dizzying array of goods, which is now a brainteaser.
While wattage has been used to identify bulbs for a long time, it actually measures energy, not light output. Lumens are units used to quantify how much light a bulb produces.

For instance, a 60-watt incandescent lamp emits 800 lumens of light. Additionally, LED bulbs can produce the same quantity of light using as little as 10 watts and are more energy-efficient than their incandescent counterparts.
According to the Environmental Protection Agency, Americans would save close to $700 million annually in energy expenses if they switched just one incandescent bulb out for a "Energy Star"-rated LED or CFL in every home.
But given the wide variety of bulb kinds, prices, and lifespans available today, many customers are perplexed.
We received a lot of feedback after asking for your inquiries regarding light lamps. To respond to your most commonly asked questions, we therefore contacted Noah Horowitz, director of the Center for Energy Efficiency of the Natural Resources Defense Council.

(It should be noted that the nonprofit environmental group Natural Resources Defense Council is a major supporter of energy-efficient lighting. A tiny portion of its funding comes from grants from the government, including one from the EPA's Energy Star program, which aims to speed up the adoption of energy-efficient equipment.

Why do some CFLs lose power so rapidly? The entirety of the seven-year existence seems arbitrary. Some of my plants last for years, while others only last a year.
Buy only CFLs with the Energy Star logo, as not all CFLs are made equal. The Environmental Protection Agency has strict performance standards for those bulbs, and they must clear numerous tests, including longevity, in addition to being effective. Your CFL's life may be shortened if you frequently turn it on and off. Additionally, in extremely cold temperatures, CFLs might not turn on or reach their maximum brightness.
Everyone I've spoken to claims they simply dispose of deceased CFLs in the garbage. Is this not an issue for landfills? In a few years, will we start to hear reports of hazardous mercury concentrations in the air, water, and soil?
Mercury levels in CFLs are currently as low as 2 mg per light. Customers should benefit from the free CFL recycling programs provided by reputable stores like Home Depot and Lowe's. Despite the fact that incandescent bulbs don't contain mercury, you should be aware that because they consume four times as much energy as CFLs to create the same amount of light, they contribute significantly more to mercury emissions into the environment from coal-burning power plants.

Three-way bulbs (50/100/150) are used in at least three of my lights because I like having the choice of brightness. Is the three-way light available in a CFL or LED version?
There are two excellent options if you want to use an energy-saving bulb and have various lighting levels. You can purchase a three-way CFL that offers low, medium, and high light output if your socket has three positions, just like your previous incandescent bulb did. Nearly all LEDs are dimmable, giving you even more freedom if your fixture is dimmer-compatible.
For candelabra lights, are CFLs or LEDs available? Consider using globe-shaped lights on my bathroom cabinet.
The good news is that almost every outlet can use an energy-efficient CFL or LED. These include the round globe-shaped bulbs that are frequently used in the restroom vanity over the sink, candelabra or flame-shaped bulbs, and others. CFL candelabras and globes have been around for a while, and now LED versions are as well.
Some of my outlets can only accommodate 60-watt bulbs. Can I use a brighter light if I use an LED or CFL? For instance, a 13-watt CFL has a 60-watt incandescent's comparable power. Should I switch to a 23-watt LED instead? I'd get the equal of a 100-watt incandescent as a result.
One should not install bulbs that are higher rated than the stated rating because fixtures have safety ratings (such as "do not exceed 60 watts"). You'll be good as long as you don't use a bulb that draws more than 60 watts in that socket.
