i use low energy light bulbs each time you switch them on they seem very dull but gradually get brighter.

It's to do with the sensitivity of the eye to the colour spectrum emitted by the bulbs. A light meter will probably show that tungsten and low-energy bulbs are emitting around the same amount of light, but your eyes don't think so. I mentioned this to a supplier, who said 'we're still working on that'. They obviously haven't got it right yet!
I try to use the next highest equivalent wattage to a tungsten bulb. Thankfully there are now 125w low energy bulbs to replace my 100w tungsten ones.
