Led Downlights - Why Buy Now? If you wander into your local DIY superstore and go to the led downlight section you will find that displays of LED downlights are becoming more visible. The most common are direct replacements for GU10 mains voltage halogen downlights (same size & shape and you dont have to change your light fittings). However one look at the price and the guaranteed reaction is EXPENSIVE!But is it?A halogen bulb costs around a £1.00 compared to about £18 for a 4 or 5 watt LED. Eighteen times the cost.However LEDs use less power, last longer and dont generate as much heat.A typical LED downlight is rated at 25,Ralph Lauren Outlet Store,000 hours whereas a mains voltage halogen bulb is good for 1,000 hours. So buying one LED light is equivalent to buying 25 halogen bulbs. A net saving of £7As far as power consumption is concerned LED consume a tenth of the power of halogens. If you assume that electricity costs 10p a kilowatt hour a 5 watt LED consumes £12.50 during its lifetime. Compare this to 50 watt halogens which will cost £125 to run. A net saving of £112.50The third consideration is heat. Halogens get hot so you cant wrap then in insulation without asking for trouble ( increased fire risk, melted cables,Ralph Lauren Outlet Online, bulbs frequently popping). If you install them according to the manufacturers instructions halogens need a gap in the insulation around each downlight.

LEDs dont get hot so you can insulate and save on your heating bills.So do you replace your halogens with LEDs or not? The only disadvantage is initial cost but if you take a longer term view each LED saves you over £100 during its lifetime.As with all new technological innovations prices start high but decrease as sales increase. You can wait until led downlight prices come down or you could be proactive. Just buy one and try it. You will save money,Ralph Lauren Outlet Online, you are reducing your carbon foot print and you are helping to increase those sales volumes which will bring prices down.
