Warm white and cool white lamp, where from

[grandfortune]

hi all,

At a house the other day and dining and office lights had a lamp in that when you switch off and on quickly it swapped temp from warm white to cool white as and when you switched it, anyone know where I can get some on these . Looked really cool and gave you that choice if needed .

Cheers
Grand
