LEDs Leading Lighting


75% of Commercial Lighting
will be LED by 2030

Some estimates put the new form of lighting using LEDs or Light Emitting Diodes at 75% of all commercial lighting by the year 2030 - replacing CFLs, halogen and other types of lights.

There are millions of lamps lighting 24x7 in office buildings, hospitals, shopping malls, hotels etc. It is easy to see whay commercial buildings account for nearly half of total energy consumption for lighting against a quarter for homes.

CFL bulbs (Compact Florescent Lamps) are a big improvement over the ancient technology of filament lamps which were the first type of electric lamp ever made. LED or Light Emitting Diode lamps are that more efficient again than CFLs over filament lamps plus they have the huge advantage of lasting for 15 years or more without maintenance or replacement. Unlike CFLs they can also be dimmed, changed in colour and are virtually unbreakable.

One big installation of LED lamps is at the Hard Rock Hotel and Casino in Las Vegas where they replaced halogen lamps. This change has cut the annual energy costs from $18,000 to $1,900 Wow that must be a worthwhile saving.

British Airways London Eye replaced fluorescent with an LED system, eliminating former maintenance costs and requirements while gaining the ability to produce spectacular colour effects.

The idea that LEDs are still relegated to flashlights, taillights and electronic gadgets is a misconception. Some major landmarks, towers, and bridges around the world, and the world's largest spherical building are all lit by LED lights. LED lighting is one of the most versatile, safe, economical and long lasting types of lighting currently available.
