LED Lighting


LED (Light Emitting Diode) lighting has become incredibly popular due to its energy efficiency, long lifespan, and versatility. Here’s a brief overview:

What are LEDs exactly? LEDs are semiconductor devices that emit light when an electric current passes through them. Unlike traditional incandescent bulbs, they don’t rely on heating a filament to produce light, which can make them much more energy-efficient in many circumstances. The first Visible Spectrum Light was invented by Nick Holonyak Jr. in 1962 while working at GE. Simply put, it is light in the electromagnetic spectrum that is visible to the human eye.


The Technical Details


(no worries, no test)


A light-emitting diode (LED) is a semiconductor device that emits this visible light when electric current flows through it. Electrons in the semiconductor recombine with electron holes, releasing energy in the form of photons. The color of the light (corresponding to the energy of the photons) is determined by the energy required for electrons to cross the band gap of the semiconductor. White light is obtained by using multiple semiconductors or a layer of light-emitting phosphor on the semiconductor device. 

The Advantages of LED Lighting

Energy Efficiency

LEDS consume significantly less energy in comparison with many traditional lighting options, which can lead to reduced electricity bills.


LEDs consume significantly less energy in comparison with many traditional lighting options, which can lead to reduced electricity bills.


Less frequent replacements as LEDs have a longer lifespan than incandescent bulbs and even CFLs (Compact Fluorescent Lamps).

Instant Lighting

LEDs light up instantly, unlike the warm-up time needed for some other lighting technologies or color/brightness decrease with age.

Color Temperature, Hue and Direction



LEDs come in various colors and can be easily adjusted or combined to create dynamic lighting effects. LEDs emit light in specific directions, which reduces the need for reflectors and diffusers. This is particularly useful for focused lighting applications, as in theatre or various performance venues.

LED Basics

Lumens, not Watts

Instead of focusing on wattage, look for lumens to determine the brightness of an LED bulb. Wattage measures energy consumption, while   lumens measure light output. A simple efficiency scale is Illustrated here…


Check if the LED bulbs or fixtures are dimmable if you want to have control over the light intensity for one or multiple areas.  

Color Temperature

LEDs come in various color temperatures, measured in Kelvins (K).   Warmer temperatures (<2700K) produce more ambiance, cooler     temperatures (5000K>) provide a more daylight-like illumination.


Invest in high-quality LED products from reputable manufacturers for better performance and longevity.


Applications of LED Lighting



Commercial Lighting


Commercial LED (Light Emitting Diode) lighting refers to the use of LED technology for illuminating commercial spaces such as offices, retail stores, warehouses, factories, hotels, and other business establishmen

Commercial LED lighting offers businesses a cost-effective, energy-efficient, and versatile lighting solution with a wide range of benefits. It’s essential to consider factors such as color temperature, lumens, beam angle, and controls when selecting LED lighting solutions for specific commercial applications

Home Lighting


In homes LEDs can be used for general lighting, task lighting, and accent lighting in both indoor and outdoor environments. LED pr0ducts are available in various forms such as bulbs, strips, and panels.

LED lighting is an ideal choice for residential applications due to its energy efficiency, longevity, design flexibility, safety features, and ability to enhance both aesthetic and functional aspects of home lighting. While the upfront cost might be slightly higher, the long-term benefits make LED lighting a cost-effective and sustainable choice for homeowners.

Outdoor Lighting



LED lighting is a smart choice for outdoor commercial lighting due to its energy efficiency, durability, customization options, and ability to create safe and inviting outdoor environments. LEDs are popular for outdoor applications like street lighting, parking lots, and architectural lighting.

Careful planning and consideration of factors such as light distribution, color temperature, and fixture placement are essential to achieving the best results in outdoor lighting applications.

Decorative Lighting


LED lighting is a versatile and popular choice for decorative and mood lighting due to its ability to provide a wide range of colors, intensities, and control options. Whether you’re looking to create a cozy ambiance at home, set the mood in a restaurant, or enhance the aesthetics of an event space

Signage and Displays

LED lighting is widely used for signage and display lighting due to its versatility, energy efficiency, and ability to provide focused and vibrant illumination.

Whether you’re looking to highlight retail displays, outdoor signage, museum exhibits, or any other type of visual presentation, LED lighting offers several advantages are used in electronic displays, billboards, and signs due to their bright and vibrant colors.


A few notes on installation and maintenance:

  • Follow manufacturer instructions for proper installation.
  • Keep the fixtures clean to maintain optimal light output.
  • LEDs don’t typically “burn out” like traditional bulbs; they gradually dim over time.

When LEDs reach about 70-80% of their initial brightness, consider replacing them.


Always remember that technology is constantly evolving, so it’s a good idea to check with current sources like Commercial Lighting Specialties for the latest information and recommendations regarding LED lighting.
