LED Lighting 101

LED stands for Light Emitting Diode. These diodes create light through a process called electroluminescence, during which an electrical current is passed through a semiconductor, which then emits light. LEDs are quite small and can be combined in a variety of ways to create different lighting products, such as light bulbs, strips, strings, and more.

LEDs last longer, are more energy efficient, have a lower environmental impact, use lower voltages, emit no UV or heat, operate in extreme temperatures, and can be combined in many different form factors for any application.

According to the U.S. Department of Energy, LED lighting lasts 3–5 times longer than compact fluorescent lights (CFLs) and up to 30 times longer than traditional incandescent lights. Depending on the product and amount of use, some LED lights can last over 10 years.

Yes! Compared to traditional lighting such as incandescent and fluorescent lighting, LEDs use less energy and produce more visible light. Much of the energy used by incandescent bulbs actually creates heat, not light, or light not on the visible spectrum.

The main drawbacks are higher upfront costs and potential compatibility issues with older dimmer switches or fixtures. However, these are often outweighed by the long-term energy savings, durability, and reduced maintenance costs.

Yes, LEDs do degrade, but very slowly. Instead of burning out suddenly like traditional bulbs, they gradually lose brightness. Most quality LEDs maintain over 70% of their initial brightness even after 100,000 hours of use.

LEDs produce very little heat compared to incandescent or halogen bulbs. However, they do generate some heat at the base or heat sink, which is why proper fixture design is important for performance and longevity.

LED lights are energy-efficient, long-lasting, emit very little heat, and are environmentally friendly. They also offer better light quality and lower maintenance costs over time.

Yes. LED lights don’t contain mercury like fluorescent bulbs and they emit very little heat, making them safer to use in homes, businesses, and industrial settings.

Yes. Many LED products are rated for outdoor use, including wet or damp locations. Look for IP ratings and weatherproof fixtures designed for outdoor environments.

Some LED lights are dimmable, but not all. To use a dimmer, make sure you choose an LED labeled as dimmable and use a compatible dimmer switch for best performance.

Color temperature is measured in Kelvins (K). For a warmer, more relaxed feel, choose 2700K–3000K. For bright, clear light in workspaces or retail, 4000K–5000K is ideal.

Flickering is usually caused by incompatible dimmer switches, power fluctuations, or poor-quality LEDs. Choosing high-quality, properly rated LED products helps prevent this.

No. Unlike fluorescent lights, LEDs turn on instantly at full brightness, even in cold temperatures.

Yes. While LEDs don’t contain hazardous materials like mercury, they can and should be recycled to reclaim valuable components and reduce landfill waste.

Lumens measure brightness. The higher the lumen count, the brighter the light. This is a better indicator of light output than wattage, which measures energy use.
