Household Halogen Lighting and Energy Saving LED Replacements
Energy saving LED home lighting is without doubt the future of domestic
lighting. Though some critics still harp on about cost and comparison with
conventional domestic lighting solutions, they miss the point as completely as
comparing an abacus with an electronic calculator.
And, as ever, it’s the money that really talks. A typical 50w GU10 halogen lamp
costs about $3 in Australia and lasts (let’s be generous) 2,000 hours. An LED
equivalent will at present set you back 7 times that but will last 25 times
longer; so on true like-for-like purchase costs you actually save (3*25 – 21)
$54.
But that’s not even close to being the end of the matter; assuming modest
domestic usage of 5 hours per day, the electricity savings from just one LED
bulb compared to the equivalent brightness halogen lamp work out at $19.83 per
year and $543.21 over the full lifespan of that one light bulb.
It may not seem like much but if you’re like most folk your lighting usage is
almost certainly somewhat is excess of one bulb for five hours per day. If you
crank the maths you start to see typical savings for an average household that
start at $400-$500 per year (or $11,000 – $15,000 over the typical lifespan of
an LED) and go up from there.
