Yes the new SMD’s work. They use 2.5watts of power and to date we have 300 installed and not one failure. At last we have a halogen comparable replacement which costs 5% of a equivalent 50W halogen to run, but with very similar light output. We hope to be selling these shortly online on our Ebay shop.
Today had a chat with a new supplier refered to me through a good ebay contact. I have now got suppliers for SMD’s (Surface Mounted Diodes) which are brighter than LED’s and use a similar amount of power. I have 300 GU10 bulbs comming each with 48 SMD’s rated at 2200mcd per SMD, in English it means I have found a direct replacement for bright 50W halogens!
This supplier can also supply B22 candle and bulb light fittings at 200LUX! So hopefully lights are finally sorted once replaced they will not need replacing for around 3-5 years.
Todate since January 2009 89 of our 500 LED lights have failed! This is saddening as they cost £6+ each. However spoke to the supplier and we have come to an arrangement. However, overall the concept of LED has been proved. We are sourcing some replacements at £9 per light, which give out 50watt of light for 2.5watts of power. Not all things work first time, but prove the concept and people quickly get on board. LED lights SHOULD last around 50K hours where as a fluorescent lasts around 5K hours. The replacement lights have had a 100 success (non failure) rate, so hopefully we can resolve this shortly.
Today we finally received 250 2.5w 60 LED GU10 bulbs. 185 are for the corridors of the Health Club and Spa Treatments; these corridors are lit for 15 hours per day, each bulb was a 50watt halogen; this equates to around 22 tonnes of CO2 per year (about 2 average households) and they cost £5600 per annum in electricity costs.
The LED replacement bulbs cost roughly £6 each and the cost of fitting each bulb with various adapters is around £8 giving a total cost to replace these 185 bulbs of roughly £2500. Fortunately these replacement bulbs are 3watt each (considerably less than 50watt), they will still be on 15 hours per day but will now produce only 1.31 tonnes of Co2 and cost around £350 per year to have lit. We got these bulbs from Graham Smith of Future Green Light on Ebay shops.
Today I have finally ordered LED lights for the hotel; having proved the concept at home I have finally found lights with an acceptable brightness and Kelvin in LED.
So I have ordered the LED bulbs for the Spa. There are presently 185 of them in total lit for 15 hours per day, each bulb is a 50watt halogen; this equates to around 22 tonnes of CO2 per year (about 2 average households) and they cost £5600 per annum in electricity costs.
The replacement bulbs I have ordered are LED and I have managed to get them for £5.80 each and the cost of fitting each bulb with various adapters is around £8 giving a total cost to replace these 185 bulbs of roughly £2500. Fortunately these replacement bulbs are 3watt each (considerably less than 50watt), they will still be on 15 hours per day but will now produce only 1.31 tonnes of Co2 and cost around £350 per year to have lit.
So you can be green and be making economically sound decisions at the same time!
Today I received £250 of LED lights from China for home, they are in various forms GU10 60 LED, BC22 (uk bulb Fitting 48 LED). I have done a calculation on the energy consumption below for my kitchen.
I have 20 50 watt GU10 bulbs in my kitchen on for around 6 hours a day which costs £220 per annum; I have changed these for 20 48LED 2.5 watt bulbs at a total cost of £120 these and they would cost £10.95 per year to run; pay back is 7 months!
No brainier; the bulbs on a bench test seem to use between 2.5W to 3W depending on which bulb, is this the future of lighting; changing them is a doodle as LED’s run cold though you need to let the fitting which had the halogen bulb in cool down first or they will not light up immediately!
UPDATED November 2008; I was in B&Q today and they have also started selling LED lights not as bright as the ones from China but it is a start.
