We have all heard the saying “It’s what’s on the inside that counts,” and in lighting, nothing could be more true. While all light bulbs will brighten your space, incandescent, halogen and LED bulbs are each unique in their design and benefits.

The signature yellow glow of an incandescent bulb has been around for 150+ years, and has been invaluable in its time. This age-old design is straightforward using a filament that is resistant to electricity. When electricity is introduced, the filament heats up and light is emitted.

An incandescent lasts about 1000 hours before it burns out. They are less energy efficient than other products on the market and as a result, many countries have passed legislation to phase them out entirely. In Canada, all production of incandescent products will cease by the end of 2014—If you are fond of the older-style bulb, now is the time to stock up.

Patented more than five decades ago, halogen lights offer an improvement on traditional incandescent technology. Although these bulbs still contain a tungsten filament, the incorporation of gas differentiates the design helping halogen lights outshine and outlast their incandescent predecessors.

When halogen gas is paired with the tungsten filament, it triggers a chemical reaction that extends the life of the inner bulb components, and subsequently, increases the lifetime of the bulb.

LED, or Light-Emitting Diode, technology is in a league of its own in many ways. Instead of a tungsten filament, LEDs contain a semiconductor surrounded by glass or translucent plastic. Once electricity is added to the mix, electrons inside the bulb spring into action to generate light.

Unlike halogen bulbs, which produce bright white light and have a standard design, LEDs are available in a range of colours, shapes and sizes. They also produce very little heat, are more durable than halogen offerings and use a fraction of the power.

LEDs are the most energy-efficient of all bulbs to date, offering significant energy savings over time. They also last the longest—bulbs might need changing every 20 years, rather than every year or more.

Things certainly have evolved in the last few decades, and there is no doubt advanced bulb innovations will continue to come to light in the future. But for energy savers looking for an efficient way to light their homes and workplaces, LED is an advanced and reliable option that won’t disappoint.
