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

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

Selecting the correct beam angle of any Light Bulb is very important. The enclosed interactive beam selector allows you to see exactly how important. A beam angle is measured in degrees, and that refers to the width at which the light emanates from the bulb. The angles vary considerably depending on the type and style of the bulb, so to help you select the most suitable option we have divided our bulbs into four main categories, Narrow, Medium, Wide, and Very Wide beam. The most common beam angles for the domestic home are 24-26 degree (medium) or 36-38 degree (wide).
