Advantages

The loss of cathode emission materials, due to evaporation and sputtering caused by ion bombardment, limits the life of fluorescent lamps to between 5,000 to 20,000 hours, while the life of induction lamps on the market today reaches 100,000 hours. This makes it beneficial to use such lamps in applications where lamp maintenance is expensive.


The elimination of electrodes and their power losses opens up unlimited possibilities in the variety of possible lamp shapes and increases their efficiency respectively. The presence of hot electrodes limits the fill gas pressure and its composition to avoid chemical and physical reactions that destroy the electrodes.


There is no such restriction in induction lamps, where gas pressure is optimized for maximum efficiency. As far as lamp rating of fluorescent lamp is concerned, cathode emission takes place from a tiny spot heated by the discharge current, which cannot be over 1.5A
this limits the maximum power rating and light output of these lamps (e.g. the highest rating of high output T5 lamp is 80W).


For induction lamps, there is no such restriction and rating of lamp could be up to 200W. Theoretically, induction lamps have instant and harmless starting and are more convenient for dimming, as maintenance of high cathode temperatures during dimming are no longer required.
