LED Dusk to Dawn Sensor Light Bulbs

LED Dusk-to- Dawn Sensor Light Bulbs contain built-in sensors that detect the sun’s natural light. They’ll power up when the sun goes down, providing excellent light output through the night. Then, when the sensors detect the sun coming back up, the bulbs will slowly shut down.

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.


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 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, 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.


A UK based manufacturer founded in 1994, Megaman have quickly established themselves as a leading brand in the lighting industry. Their success started when they manufactured the world's first CFL GU10 Lamp in 2002.


A manufacturer with over 40 years of lighting industry experience. Cost effective without compromising on quality, some highlights from Prolite are their Energy Saving Spirals and LED G9 Capsules.


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.


Bayonet is a style of light bulb cap/base, this base is locked in place by pushing down and turning clockwise. Bayonet light bulbs have two pins, double contact base and can mainly be found in the UK.


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 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 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.


Ba22d is the technical term for Bayonet or BC capped light bulbs. This base is 22mm in diameter and has two pins which twist and lock into the lamp holder. The "d" at the end of the code refers to the double contact on the bottom of the lamp.


E27, or Edison Screw (ES), is a type of screw in lamp base with a 27mm diameter. Very common, the E27 base is found on a variety of different light bulbs, including GLS, Candle and Golfball Lamps.

Edison Screw

Edison Screw is the term describing the screw in base developed by Thomas Edison in 1909. There are now a wide variety of different edison screw caps; E5 (LES), E10 (MES), E12 (CES), E14 (SES), E27 (ES) and E40 (GES) to name a few. The most common type of Edison Screw base is E27, which measures 27mm in diameter.
