What is Lumens, Watts, Kelvins on LED Lights?

What is Lumens, Watts, Kelvins on LED Lights? With the advent of LED lights, I’m often asked about the terminology found on packaging and light globes in regards to LED lighting. What do all those numbers and letters on the light globe or light fitting mean? A little more technical than my usual articles but hopefully it will help with choosing your light fitting or globe. I’ll highlight the three most useful terms to know; Lumens, Kelvins and Watts. Lumens (lm) Lumens is the total amount of visible light given off by the globe or light fitting. It is the brightness of the globe. Therefore the higher the lumens, the brighter the light. The lower the lumens, the dimmer the light. You will find this commonly printed on light fittings. Shown as a number ie 800lm (800 Lumens). While in the past we chose light fittings based on wattage, with LED’s we now select on Lumens, consequently it may take a little getting used to! As an example, the old common 60W light globe gave off about 800 Lumens. Kelvins (K) Kelvin is a number unit that is used to describe the colour temperature of a light. You may have heard of lights referred to as warm or cool. Lights in the 2700-3000K range are yellower and considered to be warm, sometimes called Warm White (WW). Warm lighting is often seen as soft and relaxing and used in bedrooms and living rooms. Lighting around the 4000K range is called Cool White (CW), the light colour being more blue/green and appearing brighter to the eye. This light type can be...
Ceiling Fans to Save Energy Costs

Ceiling Fans to Save Energy Costs

Save Money and Electricity using Ceiling Fans While writing this blog I needed to look up how much we are paying for electricity in Adelaide. Imagine my surprise, even as an electrician, to find out we not only pay the most in Australia, but it’s also one of the highest in the world! No my intention isn’t to get you all hot under the collar, I’m going to help out by explaining why ceiling fans are such a good way to save money on Electricity in Adelaide, especially during the hot summer. Most of the ceiling fans I’ve installed use around 60-65 watts of power, about the same as a bedroom incandescent light globe. Calculated for Adelaide electricity prices that equates to approximately 2 cents an hour to run. That’s all good news and you’re going to read similar stories all over the internet, but let’s look at the best ways to actually save money and not spend more! I’d like to just add a quick comparison I’ve worked out to run your home air conditioner. An evaporative air conditioner can cost up to 40 cents an hour to run and almost $2 per hour for full house ducted reverse cycle. Here’s a couple of tips for correctly using a ceiling fan to save money As you know a ceiling fan does not actually cool the room down. It works by providing a breeze or airflow around the room. This breeze evaporates moisture on your body and in turn cools the body, using the body’s natural air conditioning system. On hot days and nights where an air conditioner needs...
