Long lifespan due to the lack of electrodes – Strictly speaking almost indefinite on the lamp itself but between 25,000 and 100,000 hours depending on lamp model and quality of electronics used;Very high energy conversion efficiency of between 62 and 90 Lumens/Watt [higher power lamps are more energy efficient];High power factor due to the low loss of the high frequency electronic ballasts which are typically between 95% and 98% efficient;Minimal Lumen depreciation (declining light output with age) compared to other lamp types as filament evaporation and depletion is absent;"Instant-on" and hot re-strike, unlike most HID lamps used in commercial-industrial lighting applications (such as mercury-vapor lamp, sodium-vapor lamp and metal halide lampEnvironmentally friendly as induction lamps use less energy, and use less mercury per hour of operation than conventional lighting due to their long lifespan. The mercury is in a solid form and can be easily recovered if the lamp is broken, or for recycling at end-of-life.[citation needed]
These benefits offer considerable cost savings of between 35% and 55% in energy and maintenance costs for induction lamps compared to other types of commercial and industrial lamps which they replace.
DisadvantagesSome models of internal inductor lamps that use high frequency ballasts can produceradio frequency interference (RFI) which interferes with radio communications in the area. Newer, external inductor type lamps use low frequency ballasts that usually have FCCor other certification, thus complying with RFI regulations.[citation needed]External inductor lamps tend to be quite large, especially in higher wattage models, thus they are not always suitable for applications where a compact light source is required.Some types of inductor lamps contain mercury, which is highly toxic if released to the environment.
