When it gets dark at four o’clock at night in December, the strings of coloured lights that people put up all around their houses are pleasant and comforting. However, these lights also add to an already-higher electricity bill, wasting
energy and making the holidays that much more expensive. If you still want to brighten your nights and bring some holiday cheer to the neighbourhood, why not decorate with strings of L.E.D. bulbs instead?
L.E.D.s (light-emitting diodes, a type of semiconductor that produces light) cost more at the store— these days they run between
$15 and $30 for a string, depending on the colour and length— but they also use between 80% and 95%
less energy, which makes a significant difference on a hydro bill. You can get different styles, including bulbs that dim or flash, as well as any of the colours of traditional bulbs. The L.E.D.s don’t produce as much heat as incandescent bulbs, making them far less of a fire hazard, and there is no glass surrounding the bulb that can get broken.
