lightingAt present replacing existing inefficient
incandescent light bulbs with
CFL bulbs is the best way to reducing wastage of electricity, and to
save money. However, recent developments in
LED technology have brought the day closer when
LED light bulbs will be cheap and efficient enough to make them common in homes and offices. They are already the best
energy efficient option for
spotlights offering longevity, reliability, and financial benefits, and they do not contain the
mercury found in CFL's (see
Toxic Mercury in CFL Bulbs.)
LED Light Bulbs
LED's are very cheap to manufacture, are very efficient, and typically last for around 50,000 to 100,000 hours (5-10 years continuous use) which is far in excess of CFL and incandescent light bulbs. However
LED bulbs suffer from one major disadvantage: Each individual
LED sends light out in a very
straight line whereas an incandescent or CFL bulb sends light out equally in all directions.
Therefore an LED bulb must be made up of a large number of individual LEDs pointing in different directions; and even then, they are still only really suitable for directional (spot)lights and for mood lighting (rather than for full room general lighting) - i.e. they work best as
spotlights over kitchen work surfaces or a desk, but will not light a living room adequately.
When this article was first published in the middle of 2006 we expected engineers to soon come up with an affordable LED-based direct replacement for the standard
60W incandescent light bulb (bayonet or Edison screw fitting). Unfortunately, at the time of revising this article (April 2009) we are still not there.
Our article
Pharox 240V LED Lightbulb published in early 2007 discussed a 3.4W unit designed to replace a 40W incandescent. That bulb (pictured above in its original form) has now been updated and improved, but still uses just
4 Watts of electricity. It is available with standard E26, E27, and B22 bases, and should last 50,000 hours - BUT they cost around
£30 each! Keep checking our page on the
Pharox Lightbulb for the latest information.
240 Volt LED Spotlight Bulbs
240V LED spotlights can be used to replace existing halogen spotlights and downlighters with fantastic
energy savings (as direct replacements for standard
GU10 based bulbs). A 25 Watt
halogen spotlight for example can be replaced with a 2 Watt LED spot light bulb
saving electricity and also running far cooler than its halogen equivalent. The
LED spotlight bulb will also last many times longer than the halogen bulb which will make up for the initial extra expense.
Note that LED spotlight bulbs can typically NOT be used with dimmer circuits. Attempting to use a dimmer with an LED bulb will considerably shorten its life - i.e. to 10 minutes instead of 10 years.
The Colour of 240V White LED Spotlights
The light from
LED spotlights is very different from the warm colour provided by the
halogen bulbs that they are designed to replace. It is either very white, or white with quite a strong bluish tinge (particularly with the cheaper quality
white LED spotlight bulbs) which can take a little getting used to.
The image above shows an
experiment comparing the light from a 240V 50W halogen spotlight costing £1 (light shining upwards) with that from a cheap (and nasty) 240V GU10 1 Watt
15 LED spotlight bulb which cost £4 inc VAT plus delivery at the start of 2007 (light pointing downwards).
11th April 2009 Update The LED spotlight pictured above has now been running now for 28 months for 12+ hours per day =
10,000+ hours with no sign of dimming or failing, so at least it has proved to be reliable if a little on the blue side!
