As technology advances, more information is needed to fully understand new capabilities and possibilities. When it comes to lighting, the advances and new capabilities of LED lighting are consistently improving, and learning about these advances can be confusing. With the help of energy conservationist Howard Sperling, this information, the best methods, and the most efficient ways to use LED lighting is easier than ever.
What are LED lightbulbs, and do they save energy?
Howard Sperling: LED stands for light-emitting diodes and LED lightbulbs are designed to replace incandescent, fluorescent, CFL and any high-pressure sodium and halogen bulbs. With LEDs, the electronic components convert electrical energy to light with the movement of electrons within the diode. Because of this process, they are more efficient and use less energy compared to other lightbulbs.
How do LEDs work?
HS: LED lighting is made up of three main components: the LED, the driver, and the heat sink. LEDs take the power that is created via the driver to create light and the heat sink captures the heat from the LEDs and the driver. By capturing this heat, the LEDs ill have a longer lifespan.
What are the benefits of LED lighting?
HS: Replacing your current lightbulbs with LEDs has several benefits, including:
- A reduction in your energy costs.
- Less heat created by lighting.
- Lifespans between 50,000 and 100,000 hours.
- They don’t break as easily as traditional lightbulbs.
- They do not contain mercury or other hazardous materials.
- LEDs are recyclable and most parts can be reclaimed in an eco-friendly way.
What colors are LED lightbulbs available in?
HS: LEDs are available in most colors, including red, orange, yellow, green, blue, purple, and pink. Regular light LEDs have different classifications of white, with the main colors being “warm white” and “cool white”.
The temperatures of LED lightbulbs can be confusing, especially when the white LEDs have several labels. Keep in mind that warmer lights have more yellow tones and cooler lights have more blue tones.
Can LED lightbulbs be used outside?
HS: Yes! Most LED lightbulbs are designed with water-proof fittings. It’s important to read the instructions and manuals on your LED lights before placing them outside, as this can differ.
Should I buy LEDs based on watts or lumens?
HS: When purchasing LEDs, you always want to buy based on lumens, as watts are a number associated with the amount of energy it takes to produce the lumens. On the packaging of LED lightbulbs, look for lumens per watt or lm/w – the higher the number, the less energy that is needed to produce the light.
