SUMMARY

The discussion clarifies the differences between tube light circuits and energy saver circuits, emphasizing that energy savers consume less electricity while providing similar illumination. Tube lights typically operate at a 36W rating, whereas energy saver lamps range from 5W to 65W, with common ratings of 11W or 18W. Both types of lamps can achieve the same light output if they have equivalent lumens per watt (lm/W) ratings. The primary distinction lies in the use of integrated or external electronic ballasts and starters in their circuits.

PREREQUISITES

Why energy savers consume less electricity although they give same kind of illumination as from the tube light that consumes more energy ?

what is the internal difference between a tube light circuit and an energy saver circuit
 
Engineering news on Phys.org
tube light fittings are generally available for 36W rating, energy saver lamps are available in various ratings from 5W to 65W. mostly we use 11W or 18W which gives lesser illumination but saves energy compared to 36W tube rods. if you want same light output then power consumption will be same
 
If both the lamps are fluorescent and with the same lm/W rating, the lighting vs. power consumption is the same.

The operating principle of the two are simelar, the only different are integrated or extrenal electronic ballast and starters.

lm/W = lumens per watt
