I believe a product isn't complete unless everything is thought about. These are the wire colours, fixings and bulbs I believe work with the lampshades. 

Brass bayonet fitting supplied with either linen or burgundy 300mm length of cord. If you would like a longer length please contact me direct. 

Both bulbs bayonet fitting, 5w with LED antique bronze filament, lasting 10,000 hours. The Globe bulb for the 'Teasel' lampshades, long bulb for 'Bluebell' Lampshades.
