LED Frequently Asked Questions


What is a LED?

LED stands for Light-Emitting Diode. LEDs are small light sources that become illuminated by the movement of electrons through a semiconductor material.
 LEDs have a wide application range and are used for daylights in new cars, in LED TVs and in traffic lights.


What is a LED Globe/Bulb?

LED globes are designed to replace traditional light bulbs and fluorescent tubes by combining multiple light-emitting diodes (LEDs) to create energy-efficient and cost-saving light.


What are the benefits of using LED Globes?

LED Globes offers 5 major advantages over existing technology:

  1. More Efficient – LED globes require between 80%-90% less energy than traditional light bulbs, which equates to a massive reduction in energy consumption whilst getting the same brightness. Lights can make up to 35% of your power bill, so savings can be substantial.

  2. Cheaper to operate - While the initial purchase price is higher, the savings in power consumption over its extended lifespan more than validates the upfront cost. The upfront investment can often be recouped in the first year. LED essentially pays for itself many, many times over their lifespan!

  3. Long Lifespan – LED bulbs are rated to operate between 15,000 and 30,000 hours. This equates for a normal domestic household to a 15-20 year lifespan. In commercial applications like warehouse or retail shops, LED tubes can last over 10 years. The extended lifespan is attributed to the solid-state components. This is 3x times the lifespan of fluorescent tubes and 15x times of incandescent bulbs (1000 – 2000hrs). LED bulbs dramatically reduce the need for on-going maintenance. None of the pulling the ladder out to change bulbs! 

  4. ECO-Design – LEDs are mercury-free and emit no UV radiation making them safe for people with health problems related to fluorescent lighting.  Philips LED bulbs are manufactured without any hazardous materials, making them a safe and sustainable choice

  5. Safety  – LED Globes are all CE approved, ROHS compliant and rigorously tested to meet safety standards. As recessed lights are the most common form of down-lights in Australia, the lower operating temperatures of LED Globes reduce the potential risk of ceiling fires.


Do LED lights generate heat?

LED lights generate very little heat. They are ideal for kitchens, dens, offices, or anywhere you are working in close proximity to a standard light bulb. 


Will they fit my existing light fittings?

LEDs can be retro fitted to virtually any traditional light fitting. That means upgrading your office your home is a relatively simple procedure. Most common fittings or base caps are Screw, Bayonet, MR16 or GU10.

Existing T8 lamps on electromagnetic (EM) ballast installations can be retrofitted with Philips CorePro LEDtubes.


How does the output of LED Globes translate to traditional bulb wattage?

Are the different light colours with LEDs?

Yes. LED Globes come in Warm White (2700/3000K), Cool White (4000K) and Daylight White (6500K). Colour temperature is measured in Kelvin (K).


Which supplier is SIMPLY-LEDS.COM.AU using?

We only source products from Philips Australia. Philips is No 1 in Lighting across the globe. Our products are sourced directly from Philips Australia and are meeting all Australian safety and standards/regulations.

 The Australian market is being flooded by many cheap imports that do not meet these standards and cause potential safety or quality concerns.  


Can LED bulbs be used with Dimmers?

Yes. The product description needs to specify that the LED bulb is dimmable, not every bulb is dimmable.


Will the bulbs come on immediately, or will they have to "warm up" like the older energy saving bulbs do?

LED lights come on instantly. That means absolutely no warming up required. Furthermore, turning the LED light on and off does not decrease its lifespan.


My newly installed LED down-light flickers when I switch the light on. What is the cause for this?

Compatibility issues in your transformer cause the flickering. Please consult with your electrician.


Do I have to replace the starter with LED Tubes?

Yes. Each Philips CorePro LEDtubes comes with a starter that replaces the existing starter fuse.


Fluorescent tubes fade over time? Does this happen with LED tubes as well?

No. One of the big advantages with LED tubes is that maintain their colour and brightness over their product life.


Why does my light bulb fail earlier than its specified life?

Light bulb life is based on specified average number of hours. A bulb’s life can be shortened by shock or vibration, and by over-voltage. LEDs are vibration resistant and therefore have a much longer life than traditional lighting technologies.


How do you calculate the cost of operating a light bulb?

To calculate the operating cost per day, multiply the globe wattage by the daily hours used divide it by 1000 (electricity is measured in Kilo Watt Hours (kwh)) and multiply by your electricity providers cost per kwh.


How long will LEDs last?

If your standard Halogen is to be replaced every 1-2 years, the expected lifetime of an LED is approximately 15 times your standard Halogen. We may have a different technology around by the time you look at replacing your LEDs.
