We do not sell bulbs here at Anglepoise, however we would recommend that you buy a Philips Tornado bulb either the 12watt or the 15watt bulb. 

These can be found at John Lewis, B&Q, Sainsbury's and many other high street retailers. We recommend these bulbs as they are the correct weight to balance our lights. 

 

We suggest a spiral type of bulb as other energy saving bulb types can be longer and may stick out of the shade in use. If you are unsure about this we suggest taking your old bulb to the store and checking the length and the weight of the bulb against the new bulb.
