Types of Light Bulbs

Are you confused by the various types of lightbulbs? Some just look fancier than others, but some are designed for energy-efficiency. Let's break down the different types!

Incandescent Tungsten Bulbs – Incandescent bulbs are the “original” light bulbs.  They get extremely hot when lights are on! They are highly inefficient as 90% of the energy goes toward heat and only 10% toward actual light.  

Halogen Bulbs – Halogen bulbs used the same technology as incandescent tungsten bulbs, but they are brighter and last 3x as long.  However they are not as efficient as compact fluorescent lamps (CFL) or LEDs. 

Fluorescent Bulbs – Fluorescent bulbs, also called CFL for compact fluorescent lamps, last longer than incandescent lights and are 75% more efficient. However, they contain mercury and need to be recycled and not thrown in regular rubbish. They are also omnidirectional, which means they produce light in 360 degrees. Because of this, they are inefficient and need reflective, accessory parts to redirect light. 

LED Bulbs – LED bulbs, or light emitting diodes, use photons to produce light instead of heat. They have an extremely long life span. New LEDs can last 50,000 to 100,000 hours or more! And they are extremely energy efficient compared to any other commercial lighting technology. Although replacing your other bulbs with LEDs can be more expensive, it will certainly pay for itself in the long run.

LEDs also allow for fun, new lighting options.  The chips are smaller than any other bulb’s filaments so they are popular with strip lighting. They also can be fitted with RGB filters than enable coloured lights.  

Conclusion – As LED continues to become more popular as an energy efficient choice and technology keeps improving, the prices continue to drop. Really, there’s no downside to switching to LEDs.  Let us know how we can help create better lighting for you!
