What is an LED?
This stands for light emitting diode. LEDs are a low-energy option and more efficient in how they produce light, where an electrical current passes through a microchip, illuminating the light source.
What does wattage mean?
All light bulbs have a wattage rating which allows us to measure how bright it is. A Watt (W) is an International Standard unit of electrical and mechanical power that measures the rate of energy. The higher the wattage, the more energy consumption is used.
What are lumens?
A lumen is a measure of the amount of brightness of a light bulb. Whereas the wattage measures the power consumed by the bulb, lumens will tell you how bright it is.
Bulb Warmth – The Kelvin Scale
We use the Kelvin Scale to determine how warm or cool a light source is. Colour temperature is measured in degrees of Kelvin (K) on a scale from 1,000 to 10,000. Temperatures for most lighting usually fall between 2000K to 6500K, with the higher the number resulting in a cooler temperature. The Kelvin scale can be useful in planning what light bulb to use for different rooms, depending on their usage. For example, you might prefer a warm cosy light for a living room, and a cooler light for bathrooms or outdoors.
What is an IP rating?
IP stands for Ingress Protection mark, which declares the level of protection the bulb has against dirt and water. There is always two numbers after the letters IP; the first represents protection against liquids. The higher the number, the greater protection. Most of us only need to take notice of IP ratings when choosing lighting for bathrooms and outside spaces. Rating IP64 are sufficient for indoor and outdoor use, provided they are not entirely exposed to the elements. Most other bulbs you find around your house would likely be IP20, where they have little to no exposure to dust and water.
How to choose the right lightbulb?
1. Choose between bayonette, screw or pins/pegs. Choosing the correct bulb will depend on what type of fitting your lamp has. We call this fitting a ‘cap.’
Bayonet Cap – these are known as the ‘twist and lock’ bulb, which is the most common option if your light fitting doesn’t take a standard screw cap bulb.
Edison Screw Cap – this is one of the most common types of bulb fittings, where it screws tightly into place within the light fitting. They come in two sizes E27 and E14.
GU10 Cap – despite looking different to the traditional bayonet bulbs, these have two pins 10 mm apart. Traditionally, these bulbs are halogen, but more manufacturers are now making LED versions which are more energy-efficient.
G9 bulbs are a compact style that feature two loop pins that push into the fixture. These are spaced 9mm apart and allow a simple installation. G9 light bulbs are commonly used in decorative lighting fixtures as they are small, bright and don’t distract focus from the feature. These bulbs are available in LED and Halogen versions.
Choose between CFL, halogen or LED. This will depend on how efficient you would like your bulbs to be, as well as how bright and functional they are. CFL’s are more durable and energy-efficient than incandescent bulbs and halogen bulbs which makes them a popular option, however we would always advise using LED bulbs as they are even more energy-efficient, using around 10 watts to provide a brightness of a 60-watt regular bulb.
2. Consider how bright you want the room and select how many lumens you need. If your light is serving a function, such as a spotlight in a kitchen, then you may want to choose a brighterbulb. For more atmospheric lighting, consider choosing lower level lighting that creates a warm and cosy atmosphere.
3. Choose what colour lighting you want. Depending on what room your light is will dictate how cool or warm you will want the light. For bedrooms and living rooms, choose a warmer light, and for bathrooms, hallways, and outdoor lighting, consider a cooler bulb.
4. Choose what shape bulb you want. The most common shapes are traditional round, candle, spotlight, spiral and downlight. Most table lamps and floor lamps use a traditional round or candle lightbulb.
