Light bulb types and fittings

Find the light bulb you need with our guide to the different types, sizes and fittings.


LED's are the most energy-efficient bulbs. They use 90% less energy than traditional incandescent bulbs and can sometimes pay for themselves through energy savings in just a couple of months. So while the upfront cost might be high, you'll notice the difference in your energy bills. By contrast, Compact Fluorescent Lamps (CFLs) use 60%-80% less energy than incandescents, while halogens use 20-30% less.

The word Filament itself refers to the wire or thread inside the bulb which lights up when you turn it on.

The halogen light bulb or lamp is a type of incandescent lamp which uses a halogen gas in order to increase both light output and rated life. They are known for moderately high efficiency, quality of light, and high rated life compared to regular incandescent light bulbs.

Halogen General Lamp Shape (GLS) eco bulbs are available with an E27 or B22 base type. These dimmable, energy efficient traditional shaped lamps are direct replacements for any incandescent lamps. GLS eco light bulbs are commonly used in overhead light fixtures, reading lamps, and desk lamps.


Lumens measure how much light you are getting from a bulb. More lumens means it's a brighter light; fewer lumens means it's a dimmer light.

Colour temperature is a way to describe the light appearance provided by a light bulb. It is measured in degrees of Kelvin (K) on a scale from 1,000 to 10,000. Typically, Kelvin temperatures for commercial and residential lighting applications fall somewhere on a scale from 2000K to 6500K.

Watts are no longer the measurement used for brightness. Instead, please refer to Lumens. Watts referred to how much energy a light bulb uses. The higher the wattage, the more energy it needs.
