LEDs - Frequently Asked Questions

1. What are LEDs and how do they work?
LED stands for light-emitting diode. LEDs are small light sources that become illuminated by the movement of electrons through a semiconductor material, converting electricity into light. They do this extremely well and efficiently, converting most of the energy consumed into light and very little into heat. On the other hand, standard incandescent bulbs convert most of the energy consumed into heat and very little into light. That is why a 8 Watt LED bulb produces as much light as a 65 Watt incandescent bulb.

2. What are the benefits of replacing your ordinary bulbs with the Energy Saving LED bulbs?
The benefits are many. An immediate reduction in your electricity bill. Less heat because LED bulbs are very efficient converting electricity into light (generally around 85-90% efficient), compared to traditional incandescent bulbs (10-15% efficient) which convert most of the electricity consumed into heat. LED Bulbs last a very long time, typically 30,000-50,000 hours. Incandescent bulbs usually last 1000-2000 hours. They are virtually indestructible and they don't contain mercury and other hazardous chemicals, unlike Compact Fluorescent Light Bulbs (CFL's) that need to be disposed of carefully when their life is over. Also, 90-95% of an LED bulb is recyclable.

3. Can our products be used with Dimmers?
That depends. Some of the products we sell work fine with existing dimmer switches. Others can be dimmed with the included remote control. Others cannot be dimmed at all. Each product in our shop states clearly whether it can be dimmed or not, so please check our products page. Using an non-dimmable bulb in a dimmable application will void the warranty and will either not work at all, or fail prematurely.

4. Do these light bulbs produce a lot of heat?
NO! See Answer 2 - They are extremely energy efficient and convert most of the electricity used into visible light, unlike incandescent bulbs that convert most of the electricity into heat. That is why a 5W LED fitting can replace a 50W incandescent bulb. In fact, the old fashioned bulbs are really better heaters than sources of light! This can make a big difference in a small room in those hot summers we are always getting (!)

5. Do they contain any heavy metals like Mercury as some other energy saving light bulbs do?
No. LED bulbs do not contain mercury or any other hazardous metals or chemicals. Low Energy Compact Fluorescent Lamps (CFLs), on the other hand, do contain small amounts of mercury. They have to be disposed of carefully because of this, and if they break can be a potential health risk. LED bulbs are generally very hard wearing and much harder to break, and even if they do offer no health risks.

6. What is the colour of the light emitted from your LEDs? Are they the normal yellowish tone or are they white/blue in colour?
Our LED bulbs and fittings come in mainly Three types -  White 6000-6500K, Natural White 4000K or Warm White 2800-3000K. See our page here for further details on this.

7. What are the sizes of the bulbs? How do they operate in comparison to the original light bulbs?
Our listings provide exact dimensions of all our bulbs and fittings. In most cases however, they will be the same or smaller than the halogen bulbs they are replacing. Some CFL bulbs are bigger and therefore tend to stick out of fittings not designed for them.

8. Are LED bulbs those ugly curly, twisted bulbs that stick out of our light fittings?
No. Those spiral bulbs are CFL bulbs, and they need a spiral tube of gas that lights up when electricity flows through the tube. LED bulbs contain small, solid Light Diodes. No ugly twirls or twists to be seen!

9. Will the bulbs come on immediately, and will they have to "warm up" to brightness like the older type energy saving bulbs do?
Our bulbs come on instantly, no wait while your eyes adjust to the gloom - Full brightness the second you flick the switch! There is also no worry about constantly turning them on and off shortening their life span, making them ideal for rooms that are used often but only for short periods.

10. Can your products be used outside?
Unless otherwise stated, our fittings are designed for internal use only. However, if our bulbs are used in an IP rated fitting (as most outside lights should be), then they can be used as direct replacements for the existing bulb. We do supply some IP rated floodlights and LED strips which can be used outside and plan to stock more in the future.

11. Are there quantity discounts?
We can offer substantial discounts for significant quantities. Please contact us directly to discuss your requirements.

12. How should I dispose of a LED Energy Saving bulbs?
Our LED Light Bulbs do not contain harmful metals or chemicals, so you can dispose it like a normal incandescent light bulb. However, over 95% of the bulb is recyclable, so we believe that those who are so inclined to buy LED bulbs are also inclined to recycle. However, it is not uncommon for these bulbs to last over 10 years, so it will be a long time before you will have to be concerned about recycling your LED bulbs.

13. What sort of guarantee do our LED Energy Saving bulbs come with?
All our FSL products come with two year guarantee. If a product develops a fault, simply return it to us and we will replace it. All we ask is that the product has been used correctly and not damaged (return to us is at your expense)
