The choice of FTL over all other lamp types is mainly
due to its high efficacy and long lifetime. Linear
FTL has an even higher efficacy than common Compact
Fluorescent Lamps (known as energy saving Light
Bulbs). Unlike high & low pressure sodium lamps,
FTLs are more preferred by users for lower costs and
effective colour rendering. Having a wide medium for
distribution of light and operating at lower
temperature, FTLs are the most common lighting
solution for industrial and commercial applications.
Unlike traditional incandescent lamps (Light Bulbs),
FTLs cannot be connected directly to the electrical mains,
but instead must operate in conjunction with either conventional
electromagnetic or high frequency electronic ballasts.
