Lets look at the economics, a standard halogen 50w GU10 costs around £3 to £4, it lasts only 1000 hours, sometimes much less as they tend to burn out due to overheating.
That means you'll replace then every 6 months, so in 5 years or 5000 hours you will have spent to £40 on replacements and 250 kWh of electric at a cost of £30. A total spend of £70 per bulb!
A 9w GU10 CW Coemi Superbright LED emits a similar light but lasts for 50,000 hours, it'll still be working long after 5 years the cost id just £27 and the electric consumption in 5 years or 5000 hours is just 45 kWh £5.40. Total spend is just £32.40, thats a saving of nearly £40!! and the LED will still be going strong in 10 years!
I will for 10 times that and you haven't got the hassle of climbing a ladder every 6 months to change it!
A cheap cluster LED costs about £6 - £9 and produces only 30% of the light, that means you need 3 times the bulbs to do the same job!
Coemi Superbright LED's are up to 10 times more efficient than the common cluster type LED's sold in DIY stores and mail order tool specialists.
The ww in the description means warm white, this is a yellow tinted light ideal for relaxing areas such as a lounge.
The cw in the description means cool white, this is a bright pure white ideal for displays and kitchens.
LED's (light-emitting diode) lighting is one of the most effective ways of saving energy over conventional lighting systems.
Coemi Superbright range of LEDs are almost 8 times more efficient than halogen and tungsten bulbs producing up to 150 lumen's per watt, using focused beams to concentrate light typically in a 50% viewing angle. Typically a 4 watt LED produces a similar light to a 30 watt halogen.
These are ideal for concealed ceiling lighting, multiple lighting fittings and under floor lights. In addition they have a design life of 50,000 hours 10 times that of a energy saving florescent bulbs and 50 times that of a standard tungsten or halogen bulb.
Where else are LED's used?
Most commonly they are used in displays on mobile phones, cameras, Mp3 players, computer screens etc. Technically they are light-emitting diodes which are semiconductors that emit incoherent narrow-spectrum light when electrically biased.
LED Savings
They also have the advantage of low heat emissions, attractive space age aluminum casings, no UV or IR radiation and a design life 50,000 hours.
LED's seem most effective for mini spot lights, for example the picture below shows how effective LED's lighting a kitchen. The original 12v lighting was using 8 x 20watt halogens totaling 160watts.
Now by fitting 8 x 12v 3w MR16 CW units the total consumption is just 24watts, a saving of 136watts 85% saving. An added bonus is that the L
ED's last up to 50,000 hrs.
