Current Energy Saving Bulbs...

At the moment CFL (Compact Flourescent Light) bulbs are the most common type of bulb used to meet Part L1A and CfSH 2009 ENE3 Internal lighting criteria. They are relatively efficient lights that use approximately half of the power of traditional bulbs. They also last much longer than traditional bulbs - approximately 8,000 hours on average compared with a typical 1-2,000 hours of a halogen bulb. They do not come without their problems however; switch on a CFL light and it takes up to 120 seconds to warm up and reach full brightness. Mercury is also used in the manufacturing process and so makes recycling more complicated too.

LED...

 

In steps LED (light emitting diode). Its advantages over CFL are that it is instantly on at full brightness and no mercury is used in its manufacturing - in fact the whole product can easily be recycled as it is mostly plastic and aluminium. It also lasts much longer than CFL too - typically 40,000 hours with very little drop in performance over this time. There is also no degradation caused by turning the light on and off frequently - a problem for all other bulb types. Finally in terms of efficiency LED's really are on a different level.

 

They produce light at around 70-100 lumens per watt, that is nearly double the required 45 lumens per watt required for Part L1A or over double the 40 lumens per watt for CfSH 2009 requirements. This is also generally double the efficiency of a CFL bulb which tend to be around the 40 - 50 lumens per watt range.

In real terms this means that you can replace an incandescent bulb of 40 watts with a CFL of 10 watts or an LED of just 5 watts and achieve the same light output.

The other final advantage of LED's is that they can be produced in all sorts of shapes and sizes due to the nature of the way in which the bulb works, allowing nice variations on traditional strip and panel lighting.

When/Where can I get them?

After reading the above you may be wondering why you don't have them or see them everywhere already. There is one slight catch at the moment, LED's are only really available in low wattage/light output variants. There are quite a lot of 3-5 watt LED bulbs out there but they are only really suitable for background or mood lighting - they do not produce enough light to provide the main lighting for a room. For instance a 100 watt incandescent bulb produces around 1,000-1,200 lumens. You would need an LED of approximately 10 watts to provide the same level of light and these bulbs are not common at the moment.

However, over the next 6 - 12 months higher power LED's are set to be released which means that they will become available. thecodestore.co.uk are already in talks with our lighting manufacturers and will have a full range of lights available at competitive prices.
