How many Hammonds does it take to change a lightbulb?
Actually, rephrase that – the question should be how many lightbulbs have the Hammonds changed?
The answer is 200!
Since August last year we have been gradually replacing all of the lightbulbs in the cottages and farmhouse with the latest low wattage filament light emitting diode (LED) bulbs. Not only do they look a whole lot nicer, but they will hopefully save us a bit of money on electricity and reduce our carbon footprint. It is fitting that we have finished changing bulbs in time for Big Energy Saving Week which starts today (22 January 2018). It prompted me to work out what our estimated savings will be:
– The average wattage of our old incandescent and compact fluorescent lamps (CFLs) was 17.5 watts per bulb.
– The new bulbs are an average of 4.8 watts per bulb.
– Based on an estimated use of 4 hours a day for each bulb I calculate we will save around £460 a year in electricity (about 10% of our annual electricity cost).
– The bulbs cost us £360 to buy so we will hopefully make that back in around 9 or 10 months.
– The lifespan of the new bulbs should be around 20 years and they are guaranteed for 5 years so no more scrabbling around for spare bulbs and risking falling off ladders on changeover day. Whoop!
One of my pet hates of the old style eco-friendly CFL bulbs (the ones that with tubes going either up and down or round and round) was that they were a trap for dust and dead flies, really difficult to clean out. Plus we have numerous iron chandelier light fittings that looked just plainly ridiculous with a mixture of different designs, sizes and colours of bulbs. Now they are all beautifully uniform and so much more tasteful.
We are also in the process of getting quotes for a ground-based array of photovoltaic panels to generate our own electricity from the sun. Watch this space for more information on that.
What you can do to help…
Even though we are cutting our costs and CO2 emissions by switching bulbs you can help us to save even more and keep the cost of our holidays down while benefitting the environment by remembering to switch all lights (and the heating) off when you are out for the day and at night.
Why not look into changing your lightbulbs at home for more energy efficient ones.
Remember to check whether you can save money by switching energy provider and consider buying renewable energy instead of fossil fuels.
