Initial lamp costs maybe around 4-8 times higher but life expectancy is 20-30 time higher and energy consumption around 10-15 times lower!
We are installing a lot of 7w JCC downlights a sdirect replacments for 50w halogen downlights. They have built in LEDs and are guaranteed for 10 years!
Imagine the savings over a year in an average kitchen with 8 50w downlights, roughly £120 per year in electricity alone

We recently replaced 39x 600mm by 600mm ceiling grid light pans for a customer with led flat panels
the original lights had two 55w pl lamps in them the new flat panels are 40w each and wont degrade and need new tubes like the pl fittings. A simple calculation gives us an idea of the savings.
2x 55w = 110w. x 39 = 4290 watts or 4.29 kw when all are on.
4.29kw x 10 hours a day x 5 days a week x 50 weeks a year. =10725 KWH per year
10725 x 0.13p per KWH = £1394 per year in electricity alone, no lamp replacements.
1x 40w x 39 -1560w or 1.56kw. x 10 x 5 x50 = 3900KWH per year x 0.13p = £507 per year
A saving of £887 per year in electricity alone.
The light panels are guaranteed for 5 years. Even if every single one failed on the day aftter the warranty ran out they will have saved £4435 in electricity.
Factor in changing the pl lamps at a rate of 25% a year at £8 per lamp
£8 x 39 x 2 x 25% x 5 years = £780
£4435 + £780= £5215 saved over 5 years!
Energy saving products are now a viable reality. LED lighting replacements have come a long way in the last 2 years with lamps now offering equivilant outputs to conventional lighting.
