Light Bulb Guide by Premier Lighting

I bet in the 19th century, Thomas Edison would have never imagined that his invention would’ve evolved so much and into so many different incarnations.  At Premier Lighting we are constantly asked by our customers and from people of the general public to provide help and information on the different types of light bulbs around today.  We’ve decided to put together this light bulb guide to help inform our customers.

Light Bulb Types

Knowing your bulbs.  There are five main types of light bulbs that you would consider to use in your home.  Each type will perform differently and create a different ambiance.  Understanding the different types of light bulbs will improve the lighting in your home as some light bulbs will perform better in different locations.



An Incandescent light bulb is the most common type of light bulb around.  They’re very cheap to buy and make but are the most expensive to run.  About 5-10% of the energy used to power an incandescent bulb is converted as light, the remaining 90-95% is wasted as heat energy.  Governments around the world are trying to phase out the use of this type of bulb because it is so energy inefficient.  The lifespan of an incandescent light bulb is pretty poor, typically only lasting 750 – 1000 hours.





Halogen bulbs are more expensive then traditional light bulbs but can last up to three times longer then a bulb of the same wattage.   Halogen lights can be used on a dimmer switch and achieve maximum brightness instantly.  The downside to using these bulbs is that they’re expensive to run and have a typical lifespan of less than 2000 hours which is twice as long as incandescent bulbs.

Compact Fluorescent Lamps (CFL)

CFL light bulb

CFL lights are the most energy efficient out of all the bulbs using around 80-90% less electricity then traditional light bulbs.  They also have a good lifespan , lasting around 10000 hours.  On the flip side, they’re slow to reach full brightness and don’t generate the same colour of light as incandescent bulbs.  The bulb contains a small amount of mercury and when broken needs to be handled with care and disposed of correctly.  CFL bulbs do have a higher upfront cost but this will pay for itself over its lifetime by money be saved on energy bills and the lack of replacement bulbs in the future.




Fluorescent bulbs are simply larger versions of CFL lamps.  They come in many different sizes but are generally seen as thin glass tubes most commonly used in offices and commercial properties.  They are considered to be very energy efficient and emit very little heat using around 80-90% less energy then a traditional bulb.  Fluorescent bulbs also contain a small amount of mercury and are considered hazardous waste so they must be disposed of correctly.





Light Emitting Diode – LED

LED lights are very energy efficient bulbs and have the best lifespan out of all of the bulbs.  It has not filament or any moving parts so proves to be very durable.  A typical LED light that is in operation for eight hours a day can last around 15 years before it needs changing.  This is something to consider when using a light in a hard to reach area.  These are the most expensive bulbs to buy but because of their efficiency and durability prove to be a sound investment.



Light Bulb Fittings

There are quite a few different types of fittings but the most common are bayonet and screw.  These also come with different sizes.

Light Bulb Brightness & Power 

It is a common misconception that the wattage (W) of a bulb determines how bright a bulb is.  This is not the case as the wattage of a bulbs only determines how much energy is needed to light up the bulb.  The brightness of a bulb is measured in Lumens (lm).  Some bulbs, like LED, give off the same amount of light as a traditional bulb, bur for a much lower wattage.  This is considered more energy efficient.  So the more Lumens a bulb has, the brighter the light output.  The more watts the bulb has, the more electricity is required to power it.
