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...
Electric Oven Not Working – Adelaide Check Guide

Electric Oven Not Working – Adelaide Check Guide

Electric Oven Not Working –  Adelaide Quick Check Guide Before calling out an electrician to repair your electric oven, I thought it would be a good idea to run through a couple of self help tips. This may save you some money and get the oven working again. Sometimes it is something simple and easily over looked. If you’ve tried these tips and still have no luck, then give us a call at Adelaide Electric. Has the circuit breaker tripped or fuse blown? If the oven isn’t heating, the fan, light and clock aren’t working there is a good chance that a circuit breaker has tripped or a fuse has blown. These are most commonly found in your switch board and labelled STOVE or RANGE. Try replacing the fuse with the correct type or resetting the circuit breaker. If it blows or trips again then there is a fault that needs to be checked and best to call an electrician. Do not repeatedly try to reset the fault as there could be a dangerous situation present that needs correct testing and repair. Some kitchens can have an isolator switch that turns power off to the oven. These can be a large isolator switch or a smaller one that looks like a light switch. It’s not something that we use very often and can completely forget that it is there! Make sure it is in the on position. Some electric ovens plug into a socket that is found in a cupboard or behind a draw next to or underneath the oven. Socket outlets can be accidentally turned off when taking...
Why does my smoke alarm beep for no reason

Why does my smoke alarm beep for no reason

Why does my smoke alarm beep or go off for no reason? I’m going to answer some questions here about why smoke alarms or smoke detectors may go off or beep for no apparent reason. Keep in mind here there is a difference between the smoke alarm actually going off and that annoying chirp or beep that sounds once every couple of minutes. My smoke alarm is beeping for no reason. My smoke alarm is going off for no reason. My smoke alarm will not turn off. There are two main culprits at work in this scenario. One possible cause is that there is dust or cobwebs on or within the smoke detector unit and this is causing it to false alarm. The fix here is to clean the smoke detector using the soft brush end of your vacuum cleaner. This should be part of you smoke detector maintenance routine for optimum performance. Check out my blog on maintaining your smoke detector here…..Maintaining Your Smoke Alarm The other issue is that the smoke detector is actually faulty, in which case it will need to be replaced. There are some cheap smoke detectors available on the market and in hardware stores. From my own experiences I’ve found they seem to suffer from false alarms a lot more often than some of the well-known and supported brands. My smoke alarm is chirping. My smoke alarm chirps every couple of minutes. If your smoke alarm is chirping or beeping once every minute or couple of minutes this is completely normal and a sign that the battery needs to be replaced. Smoke alarms...
10 Smoke Detector Alarm Tips

10 Smoke Detector Alarm Tips

10 Smoke Detector Alarm Tips to Keep Your Home Safe Monthly checks – It’s a simple task, once a month press the test button and you will hear a loud audible alarm. Sometimes it will take a second or two before the alarm sounds. No alarm means a flat battery or faulty smoke detector. 93% of us don’t do these checks! Replace the battery – Once per year change the smoke alarm battery. Do this regardless of whether the battery is working or not. Choose a date – Choose a specific monthly and yearly date for the monthly test and yearly battery change. Perhaps first day of the month and first day of spring?     Clean Me – It’s out of sight up there on the roof but needs a quick dusting or run the soft vacuum nozzle over it. This will keep the sensor area free of dust and cob webs and ensure the smoke detector will work correctly. Not Paintable – Do not paint the smoke detector. The sensors for smoke can be damaged by paint. If you’re having the house painted be sure to mention this to the painter, unfortunately we come across painted smoke alarms regularly. Mains Powered – If you don’t have any mains powered smoke alarm and still relying on cheap battery only alarms, it’s time to upgrade! Mains powered alarms still have a battery backup for your safety.     10 Years Old – 10 Years is the recommended lifespan for a smoke alarm and at this stage it is a good idea to have it replaced.

Ceiling Fan FAQ Adelaide

Ceiling Fan FAQ Adelaide

Ceiling Fan Frequently Asked Questions When it comes to ceiling fans I find my clients have a lot of questions, and are unsure about the many types of ceiling fans, installation techniques and what it all means for them. Here I have compiled FAQ’s that I get asked often, as well as some information that you will find informative. How much do ceiling fans cost to run? A Ceiling Fan is cheap to run at about 2-3 cents per hour. Here’s a great link for calculating any appliance costs in Adelaide Calculate Appliance Running Costs. A Ceiling Fan will also aid in saving cooling costs when used in conjunction with home air conditioners. What does the Summer/Winter switch do? This switch is found above the motor on the ceiling fan and sometimes labelled S and W. In the Summer position, the fan will blow cooling air down that you can feel. In the Winter position, the fan will turn in reverse. This blows warm air over the ceiling and down the walls. What does the number of blades mean? The most common are 3, 4 or 5 blade fans. There’s not a lot of difference in air flow. A 5 blade fan has more drag and will require more power to run the fan. A 3 blade fan is usually a metal blade fan designed to push a lot of air for its size and thus can be a little noisy. A 4 blade fan tends to be a good compromise for air flow and efficiency. Very large fans may have more blades due to design and aesthetics. Metal...
Ceiling Fan how to fix wobbly fans

Ceiling Fan how to fix wobbly fans

How to Fix a Wobbly Ceiling Fan Let me start off by saying a small amount of wobble is fine and most fans will show some signs of a wobble. However more pronounced wobble can appear to be a nuisance or something may be wrong with the fan. Here are a couple of reasons why a ceiling fan may wobble or vibrate; • Ceiling fan fixing screws are loose or wrong type • Incorrect mounting of ceiling fan or lack of fixing to structural member • Poor quality ceiling fan • Loose screws fixing blades to fan body • Warped or damaged blades • Blades out of alignment • Blades out of balance The most common issues are; blades which have been damaged or hit and cause the fan to become out of balance, poorly aligned blades or blades out of balance from new. Luckily there are a couple of checks and repairs you can attempt yourself. A note on checking loose fixings to ceiling. I noticed there’s a couple of informative articles that tell home owners to check the tightness of the ceiling fixing screws. While this is a relatively simple task it does involve removing the top bell cover which exposes the supply cable(s) and electrical terminations. Even as an electrician, when performing this task I would be isolating at the switch board and testing that the circuit is not live. Using tools and having body parts within touch reach of electrical supply is not a safe practice. Also keep in mind that even though the fan is not ‘on’ there can be live looped cables present....
