LED, Induction, and Fluorescent Lighting

Induction Lights and LED are considered long lasting and low maintenance which makes them the two most common retrofit choices for interior and exterior lighting areas. Both of these lights also have a higher lifespan than other types of lighting quality which makes LED and Induction Lights two of the most popular types of lights. They are often used in wallpacks, pole lights, street lights, tunnels, parking ramps, parking lots, garages, and many other outdoor systems where it’s usually difficult to change bulbs on a regular basis. Fluorescent Lights are commonly used inside stores, warehouses, etc.

LED’s (Light Emitting Diode) are becoming more and more popular among businesses, commercial buildings and within your own home. They are becoming the best alternative to conventional lighting due to their longevity and efficiency. LEDs project light through the flow of electrons in a semiconductor material made of positively and negatively charged parts. In other words, when the light is turned on, the electrons flow through hole openings in the material from a negative to a positive layer which then creates light. Due to this process it allows LED lights to last longer and prevents them from the lumen to depreciate (rated life). LEDs can last over 100,000 hours before the lumen depreciates down to the 30% mark of its life expectancy.

Induction Lights are similar to the fluorescent bulb. It’s a mature product that delivers energy efficiency, low maintenance and longevity. Even though they are still considered popular, they are unlikely to have any major improvements in the future. Either way, they are still widely used in many everyday locations. Induction Lights create light by using electromagnetic fields to excite the mercury to create light. Instead of using metal prongs, which often break, the powerful electromagnet positioned outside the bulb created the light. Induction Lights can last over 60,000 hours before the lumen depreciates down to the 35% mark of its life expectancy.

Fluorescent Lights are the most common lights you’ll find inside your locations. T5 and T8 Lighting are the types most commonly used. The “T” signifies the shape of the lamp which is tubular. The number following the “T” usually is the diameter of the lamp in eighths of an inch. The T5 is 5/8th of an inch in diameter and has the highest luminous efficacy of all fluorescent lamps, which is about 100 lm/W (Lumens per Watt). They are slightly shorter and therefore will require an adapter if you are retrofitting from a larger diameter fluorescent lamp. The T8 is one inch in diameter and the lamp has a little less luminous efficacy than the T5 and is about 80 lm/W. They are 40% bigger than the T5 and can be used to replace the T12 without retrofitting the socket. The T5 and T8 lamps have an average of life expectancy from 20,000 hours to 40,000 hours depending on the type of fluorescent lamps are used (i. e.: extended life lamps) coupled with consistent hours of operations.
