I do love the Calex range. This is a spiral squirrel cage lamp which is a ES Edison Screw fitting.The glass is gold for a warm glow 2100k
Burns 4 watts of power but will give you 200 lumus of light
Fully dimmable but must be on a compatible LED dimmer.
Size is 64mm round and 142mm in height
230v mains power
Life of the lamp should be about 15000 hours
This is the light bulb only. Doesn't come with light fitting.
