Warm start and cold start technology (What is difference between warm start and cold start technology?)
Warm start:
correctly optimised ignition of fluorescent lamps whereby the cathodes need to be preheated on the ends of the lamps to the right temperature so that controlled discharge can take place. This achieves the best conditions for maximisation of the service life of fluorescent lamps.
Cold start:
ignition of fluorescent lamps without preheating the cathodes means that the emission materials from the cathodes are used up more quickly.
