LED's have been in our lives for a long time already. In the simplest of examples, they are commonly used in electrical appliances to signal that the unit is on - e.g. the little red standby light on the front of your TV. However, individual white coloured LED's were never bright enough to be considered as a lighting source. 
The combination of many LED's mounted together meant that the light output (measured in Lumens rather than watts) was a viable lighting source. This technology helped define the introduction of LED's into everyday light fittings such as GU10 spotlight bulbs. 
LED bulbs have a huge life expectancy in comparison to other technologies. The LED technology is very stable and so LED bulbs should last for between 25,000 – 50,000 hours. The life expectancy figure quoted on LED products related to the L70 value which is when the light still emits 70% of their original brightness. 
Yes, LED bulbs have been around for a few years now. Most large DIY stores stock the first generation of LED bulbs which feature a large number of individually mounted LED's. They are not generally appropriate as a direct replacement for existing bulbs throughout your home however as they simply do not produce enough light. They also tend to have a very strong blue tint to them. Technology has advanced greatly since then and you can now confidently replace your existing incandescent / halogen bulbs with LED ‘without compromising the finish. 
All of our products are CE & RoHS marked meaning that they have been tested for conformity and sustainability for use in Europe. We are among the only online retailer to have our bulbs tested independently by the test lab TUV SÜD for safety and conformity. Our bulbs have class II double insulation, thermal cut outs and EMC suppression. 
With some LED bulbs it is necessary to change existing transformers, as they will not be compatible. You would see that they are not compatible with the LED bulb as they would cause the bulb to be very dim or have a very pronounced flicker or strobe. Our Next Generation MR16 LED bulbs have been designed to be compatible with 90% of regular transformers. 
LED lights are very cost effective as the savings are twofold. Firstly, the LED technology is extremely efficient and so you will use around 90% less electricity than traditional lighting. Secondly, as the LED light has a huge life expectancy you will save on the cost of replacing the old traditional bulbs and also the hassle of physically replacing them. 
Where do we start!! Choosing LED lights is simply a “no brainer”. 
• LED lights are massively cheaper to run saving you money on your electricity bill and also saving the planet from the harmful effects of having to produce that extra electricity. 
• There are no hazardous chemicals used in LED light bulbs. 
• LED light bulbs are not fragile like traditional bulbs. 
• LED light bulbs have a life of around 30,00 hours which is around 30 times more than a traditional light bulb. 
• You can choose the colour of the light that you want from a LED Light bulb. 
• LED Lights will be standard in all homes in the future; traditional lighting has just simply been superseded by better technology. 
LED light bulbs can only be used with a dimmer switch if they specifically state in their technical specification that they are dimmable. If there is no mention of the bulbs dimming facility you should always assume that the bulb is not dimmable. 
Believe it or not, dimmer switches come in two different varieties. These are leading edge and trailing edge 
SMD stands for Surface Mounted Diode. In simple terms, this is the LED diodes / chips that are fixed to the flat surface of the bulb. One characteristic of this type of bulb is that you will get a wider beam angle than traditional bulb types, which is more desirable. 
3528 refers to a type of chip. This chip has been in production for quite some time and it actually is the size of the chip that is 3.5mm by 2.8mm. 
5050 is the type of chip used in a SMD bulb. This chip is widely used and the size of this chip is 5.0mm by 5.0mm 
6060 is the newest type of chip that has just been launched. This chip is 6.0mm by 6.0mm 
We use different chips in different bulbs in order to have a range of different prices and light outputs. The chips are the same technology but just different sizes. You would need around twice the number of 3528 chips to produce the same amount of light as a 6060 chip. 
You can save around 90% on your lighting electricity bill by swapping to LED bulbs. Yes, they do cost more than the existing filament bulbs to purchase but they will last on average for 15 years! They also produce very little heat, which is a common problem with flush mounted ceiling spotlights. 
Firstly, it can be dangerous if the spotlight does not have adequate space around it in the ceiling void for the heat to dissipate which can be a potential fire risk. Secondly, the spotlights can contribute significantly to unwanted heat in a room - particularly in summer
