Not sure which lamp or base you have? With the lamp finder you hold your old lamp against the screen and compare it with actual-size drawings: E27, E14, GU10, GU5.3, G4, G9, R7s, fluorescent tubes (T8 and T5), PL lamps (G23), GX53 and spots such as PAR16, PAR20, PAR30 and PAR38.
First you calibrate your screen with a bank card or a ruler, so the dimensions are spot on. Then you instantly see which LED lamps in stock fit.
