This lovely lamp we have on our landing. It drops down about 4 feet but its over the stairs. Came with halogens rated 20w each (times 9
). As well as power we got heat, and a couple of bulbs kept blowing. Decided to punt up for LED replacements a year ago that are about £4 each. Now using 18w and not 180w and no heat. We've had a couple of LEDs fail in the year, which negates some of the saving.
Just bought two replacements, both failed within an hour or two. £8. Took them back and ordered a cheap set off Amazon for roughly £1:20 each. These haven't failed yet.
These modern LEDs aren't cheap, but should outlast standard bulbs. It's currently on all evening, so would have been 30p for roughly 5 hours use, now 3p.
