light bulbs caps bases
Tools & Resources

The cap or base of a light bulb joins the bulb to the lamp socket in order to provide an electrical connection. Your lamp or fixture’s socket will dictate which cap or base a light bulb needs in order to fit, but there are a number of different base types and sizes to choose from, and it’s not always easy to determine which type is right for your fixture. To add to the confusion, different fixtures often feature different types of sockets. Purchasing a bulb with the wrong cap or base is a common mistake. There are a wide variety

light bulb energy calculator
Tools & Resources

Traditional incandescent light bulbs waste a lot of their energy by turning energy into heat rather than light itself. Energy saving light bulbs work in the same way as fluorescent tubes – an electric current passes through gas in a tube, making the tube’s coating glow brightly. This means they use less energy and are cool to the touch. Although energy saving light bulbs cost a little more to buy than their old technology equivalents, they save you money in the long run by reducing the amount of electricity you use. The calculator below details the annual savings you can

colour temperature
Tools & Resources

Have you noticed that some lights, such as traditional incandescent bulbs, emit a warm, yellowish light, while others emit a cooler, almost blue light? Don’t worry – your eyes aren’t playing tricks on you. Different bulbs emit light at different colour temperatures. What is colour temperature? Let’s find out. Colour temperature describes the appearance or tint of a particular light. Most bulbs emit a white light, but this white light can range from warm to cool. Think of colour temperature like you think of paint, where there are seemingly endless shades of white to choose from. In the same vein,

light bulb average rated lifetime hours
Tools & Resources

Some bulbs last longer than others. In the light bulb industry, the lifespan of a bulb is referred to as “Average Rated Lifetime Hours” (ARL). Average rated lifetime hours indicate how long it takes for a certain percentage of light bulbs in a test batch to fail, and are measured and labelled using hours and an “L rating”. For example, if 100,000 bulbs were tested and 70,000 bulbs (70%) failed after 1,000 hours, this bulb would have an average rated life of 1,000 hours at L70. Here are a few more examples: Another important aspect to take into consideration is

Not all light bulbs can be tossed in the bin. Energy efficient bulbs like CFLs and some LEDs contain materials that are harmful to the environment if not disposed of properly, which has lead lawmakers to create new legislation that aims to make properly disposing of electronic waste easier for consumers. This legislation, called the Waste Electrical and Electronic Equipment (WEEE) Directive, is now UK and European law. WEEE requires producers – not consumers – to pay for the collection, treatment, and recovery of waste electrical equipment. This means that retailers must allow consumers to return their waste equipment, including

Anything that produces light has a beam angle. A beam angle, sometimes referred to as “beam spread”, measures how light is distributed from the source of illumination onto a target area. The beam angle specifically refers to any light that falls within 50% of the maximum intensity the bulb is capable of producing. Any light outside of this angle is referred to as the “beam field” or “spill light”, which extends until the light has decreased to 10% of the maximum intensity. Regardless of the size of the beam angle you select, it is only the intensity of the beam
