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. Read this guide to find the right colour temperature for your new light bulbs.
Traditional incandescent light bulbs are very inefficient – they waste 95% of the electricity they use by turning it into heat! Under new EU rules, these bulbs are being phased out and replaced by energy efficient light bulbs – a measure that will reduce CO2 emissions by up to 15 million tons a year. Traditional incandescent light bulbs began to be phased out in 2009 when the manufacture of 100W and 60W pearl light bulbs was stopped. In September 2011, 60W clear bulbs were also banned from being produced. These lamps were not removed from sale – there are still

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
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
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
The importance of buying a branded light bulb cannot be overstated. There are four leading manufacturers of light bulbs in the world today: Whilst there are a number of very reputable and respected smaller light bulb manufacturers throughout the world, these main four account for a considerable percentage of light bulb consumption across the globe. But are branded light bulbs really better? Let’s take a closer look at three reasons why you should consider purchasing branded light bulbs: Superior research, experience, and production volume High standard of craftsmanship and quality control Warranties and product guarantees Superior Research, Experience, and Volume
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. The WEEE Directive 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
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
