I do love the Calex range.
This is a squirrel cage lamp which is a ES Edison Screw fitting.The glass is clear for a warm glow of 2300k
Burns 4 watts of power but will give you 350 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 20000 hours
