LED Lighting Terminologies.

Traditional lighting was fairly easy and uncomplicated for the average home owner, we didn’t have much of a choice.

Generally we kept a stock of 100W and 60W incandescent bulbs in the home, either the Edison Screw or Bayonet Type, they failed quite regularly so we would normally have a few of each as spares, it didn’t really matter which manufacturer as a 60W bulb was a 60W bulb, it gave the same amount and type of light.

We would also keep a few Halogens for our down lights and one or two fluorescent tubes for the garage and kitchen.

The lack of choice and the fact that the same bulb from different manufacturers gave the same type and amount of light made light selection fairly easy. The incandescent and halogen bulbs had been around our whole lives, we are quite familiar with them and how much light they generate.

We knew that we could dim the incandescent and halogen bulbs with just about any, adequately rated, dimmer on the market….no problem, except for the odd electronic low voltage transformer, we knew the domestic fluorescent was not dimmable.

Many of us probably gave the CFL’s (Compact Fluorescent’s) a try when they first came out, but let’s be serious the light was poor quality and they had this strange phenomenon called a “warm up” period, and we probably unwittingly blew up the odd dimmer here and there, CFL’s weren’t dimmable back then and still aren’t.

Yes, there is a market for CFL’s, they are a bit of a compromise option, but they are not the long term solution. Light quality is still not great. Life span, although better than incandescent, is not brilliant compared to cost and they contain chemicals that are harmful to the environment.

What do all these different Lighting terms mean?

LED Lighting offers the home owner a range of products providing different lighting levels, colours, ratings and effects that was previously unavailable with traditional lighting, what do all these lighting terms and ratings mean?


LED Lighting is available in a range of “colours” from the warmer yellowish colours to the cooler bluish colours according to the above chart.

An incandescent bulb was the same as any other incandescent bulb, no matter who made them.
They all gave the same Warm White colour of light and generated about 16 Lumens of light per Watt of power consumed.
Less than 5% of the power consumed was given off as visible light, the rest was radiated as heat which makes the incandescent light bulb a highly inefficient light source.
The incandescent bulb has already been banned in many countries, South Africa will soon follow suit.

An LED fitting with a Red, Green and Blue LED, the three LED lights can be controlled and combined to produce any colour.

Beware: Just because an LED claims it is dimmable does not mean it is compatible with all dimmers.
