Understanding LED Lighting
Lights, lamps, LEDs and bulbs
An LED lamp is a lighting product that is assembled into a lamp (or light bulb) for use in lighting fixtures. LED bulbs don’t emit heat or ultraviolet light, thus require much less electricity than regular incandescent or CFL bulbs making them a super energy efficient lighting option.

Choose the right LED bulbs by understanding their descriptions
Understanding LED bulb descriptions will help you choose the right bulbs for your home or business.
How well a light source reveals colours is often denoted by the initials CRI, Colour Rendering Index. It compares the light source such an LED with a reference standard such as daylight or a filament lamp. Until recently, the comparison was based on eight standard colours and known as Ra8. However, the preferred measure for LEDs is Ra14. This has additional saturated colours and gives a better indication of the LED’s ability to reproduce colours.
Whether the light emitted looks cool or warm is known as the colour appearance or colour temperature, abbreviated to CCT. It is often shown in sales literature as degrees Kelvin (K). Warm LEDs, 2700K or 3000K, are used where you want a relaxing light. Typical applications would be homes or restaurants with a warm atmosphere/ ambience. Indoors, they are best suited to low levels of illumination.
A lumen is the amount of light a bulb admits. The higher the lumen, the greater the output of light, though as a bulb ages the amount of lumens it puts out decreases. The LED bulb lumens rating for the traditional 60 watt incandescent bulb replacement is around 800.
