I want to replace some fluorescent D shape lamps with LEDs.
Lyco sell two types, one for electronic ballasts and one for magnetic ballasts.
GE 12.5W White LED 4 Pin 2D Bulb for Electronic Ballasts or
GE 12.5W White LED 4 Pin 2D Bulb for Magnetic Ballasts
How do I work out which ballast is in the existing fittings? They are more than 15 years old if that helps.
