LEDs

LED, or Light Emitting Diode is the term used to describe a semiconductor diode that emits light once an electrical current passes through it. In lighting, LED Light Bulbs are a leading energy saving alternative to conventional Halogen or Incandescent Lamps.

Lumens

Replacing wattage as the standard unit of brightness, Lumens is a new measure introduced with the arrival of energy saving and LED Light Bulbs. This was due to these types of bulbs being able to emit the same amount of light as conventional equivalents, with a greatly reduced power consumption.

Kelvin

Kelvin is a term used to describe the colour temperature, often displayed as just the letter K. Some common colour temperatures are 2700K, 3000K and 6500K, which relate to Very Warm White, Warm White and Daylight Light Bulbs.

GLS

GLS, or General Lighting Service refers to the traditional standard light bulb shape. GLS Light Bulbs come in a range of different wattages, with halogen, energy saving and LED GLS Light Bulbs also available.

Colour Temperature

Colour temperature, sometimes refered to as CCT (correlated colour temperature), is simply a method of describing the colour characteristics of a light bulb. Colour temperatures range from low (warm/yellowish) type colours all the way up to high (white/bluish) light. 

Colour temperature is measured in "Kelvin" which is explained in more detail below. More information can be found on our colour temperatures example page.

Base/Socket

A socket is a hollow object that is used to contain the light bulb base. Sockets are connected to the electrical supply to transfer the power to the base. There are many types of bases in circulation, some of the most popular include Bayonet, Screw In and GU10s.

Dimmable

Dimmable refers to whether the lumens on a light bulb can be varied (brighter/dimmer) while still maintaining reliability. Incandescent and Halogen light bulbs are dimmable as standard, when buying Energy Saving CFL or LED light bulbs please ensure you are ordering dimmable versions.

Volt

Voltage is the measurement of electrical potential. The majority of light bulbs in the UK run on 220-240 volts.

It is important to keep in mind that some light fittings/light bulbs require a low voltage source, therefore a transformer would be required to "step" down the volts.

Brightness

Brightness is the term used to describe the effect of luminance on an observer. The maximum brightness is said to be found in Pure White whilst the minimum is expected to be found in Pure Black.

Glare

Glare is a term used to describe the visual impairment caused by excessive brightness. Glare can be divided into discomfort glare and disability glare. Discomfort Glare is when a light source in the field of view causes an instinctive need to look away due to overall illumination being too bright. Disability glare is where a light source outside of the field of view causes reduced visibility inside the field of view.

Instant Start

Instant Start is the term used to describe the instantaneous ignition of a light bulb. The term can be used in reference to Control Gear and LED Light Bulbs.

A60

A60 is the technical term used to describe a standard light bulb shape. This shape of light bulb is also known as a GLS (General Lamp Shape).

A60 light bulbs come in Incandescent, Eco Halogen, Energy Saving CFL and LED variations.
