CFL Light Bulbs give out far less heat than normal incandescent bulbs, making them safer for use in unattended security or night light applications. This also makes them ideal for use with lampshades made of delicate materials that can be damaged by …Read More »
The beam angle of a lighting source is the angle between the two opposing points at which the light output from the light source drops to below 50% intensity. A simplified way of thinking about the beam angle of a light source is that it is the angle…Read More »
A dimmer switch is used to control the brightness of light by changing the voltage waveform applied to the lamp, originally for halogen and incandescent lamps but recently also includes CFLs and LEDs. When selecting a dimmer for LED and CFL lamps it is important to consider the total wattage of the lamps to be controlled and select a dimmer switch that that has a lower limit of less than the total wattage of the lamps.
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.
