On EHU we use the outwell caster light. Be careful it does not contain a bulb. We have whatever bulb Mr F found that was best in our little Robert Dyas.
these are brilliant for the bedroom pods too, we have one in each: http://www.mountainwarehouse.com/camping/camping-lights/camping-lanterns/24led-soft-feel-hanging-lantern-p12089.aspx?cl=BLACK
we also have an expanding led lantern for in the porch area that when not expanded is a torch :) and of course head torches for 'fiddly' jobs (NOT a euphemism haha)

Outwell Castor for us, they can take up to 40w but bearing in mind the energy efficient bulbs are much less than this you can use pretty much whatever strength bulb you want. We have an 11w in ours (I think, it's packed away at the moment), gives plenty of light in our Kampa Croyde 6 which has quite a large living area. We use a warmer bulb as some of the efficient bulbs give off a bit of a harsh blue light.
