LED Downlights - Why Buy Now?

LED Downlights - Why Buy Now?


If you wander into your local DIY superstore and go to the lighting 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 don't have to change your light fittings).One case, in particular, relates to safety issues occurring in the Chilcotin, where lightbright public pay phones are being removed from the Alexis Creek, Tatla Lake and Anahim Lake areas, and yet there continues to be no cell service available. 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 LED's use less power, last longer and don't generate as much heat.

A typical LED downlight is rated at 25,000 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 £7

As far as power consumption is concerned LED' consume a tenth of the power of halogens."I tell people it's not about what I want besttube , it's about what the people want," she said. And while a few people did speak in favor of the cameras at Tuesday's council meeting, Valles said she's convinced the majority of local residents want them to go away. If you assume that electricity costs 10p a kilowatt hour a 5 watt LED consumes £12.50 during its lifetime.He wrote on social networking site Twitter: "Frideswide Square at Oxford led strip wholesale station working well this morning with no traffic lights. Long may it continue!" Compare this to 50 watt halogens which will cost £125 to run. A net saving of £112.50

The third consideration is heat."The Today Show" will reportedly be attending a local Tea crystal Party meeting Thursday night to film a piece on red light cameras.contract with camera operator Redflex, with several bestlight attorneys looking at ways to get Victorville out of that agreement for the remaining 10 cameras before it expires in 2014. Halogens get hot so you can't wrap then in insulation without asking for trouble ( increased fire risk, melted cables, bulbs frequently popping). If you install them according to the manufacturers instructions halogens need a gap in the insulation around each downlight. This sort of defeats the idea of insulation and means that halogens are very good at heating up your loft space when they are on and cooling down your room when they are off. LED's don't get hot so you can insulate and save on your heating bills.

So do you replace your halogens with LED's 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 prices come down or you could be proactive. Just buy one and try it. You will save money, you are reducing your carbon foot print and you are helping to increase those sales volumes which will bring prices down.
