Help! How many light bulbs?

[senua]

My brain appears to be fugged by one too many mince pies!
We are looking at changing the lighting in the sitting room. The fitting is either 3-arm or 5-arm; the room is approx 12' by 24' and has two fittings points. The bulb is a G9, which is a LED 3w or 280 lumens.

Do we want two 3-arm or two 5-arm? I am much confused by watts-that-aren't-watts and my brain cannot compute.

I don't think 3 bulbs of that size at each end will be enough, so get 5 arm ones.

G9 are a bit fiddly, consider SES which are more common as LED lamps.

Many thanks. We will have to look at the fitting again as I think that it is only configured for a G9. They would say that fiddliness is not a relevant problem - it's supposed to last 20,000 hours so shouldn't need changing much!
