I have had two of these in the lounge - it is quite a large one - for several years now. Not the prettiest, I know, but the ceiling is bit on the low side (~230cm), so the low profile was the main consideration.
Problem is that the light bulbs are a nightmare... I have tried the full range available from Amazon from cheapest to the nearly most expensive, also tried both 20w and 40w. They are on for probably 3-4 hours a day, and I must have replaced each at least 2-3 times a year (I cannot think of a week where I haven't had to replace at least one).
I have now had enough (currently 4 of the total of 12 are dead...), and either the whole fitting goes - was a struggle to find something that would look ok - or it is time to do something about the bulbs. Also, even at 20w we are talking about 20 x 12 = 360w.
I came across G9 low energy ones - e.g.
Has anybody any experience with these (or similar)? They are approx x5 the price of the standard G9 bulbs that I have been using which never came anywhere near the advertised 2000 hour lifespan.
