One of the fastest and easiest ways to cut down on your energy bill is to switch to energy efficient lighting. It is easy to replace your current light with energy efficient one and it can result in potential energy savings of up to 30% Most of the lightings in older flats tends to consume more energy, for example incandescent light bulbs, T8 lamps with low efficiency electromagnetic ballast and decorative halogen spotlights, result in a substantial amount of control gear losses.


Incandescent	Decorative halogen
A less well-known area is the use of energy efficient ballast.s New electronic ballasts which are used to control many of our home lighting are designed to reduce ballast energy losses to less than 50% of the olf electromagnetic ballasts. Furthermore, these new electronic ballast operate at much higher frequencies, creating a more pleasant light by reducing light flicker and eye strain. Lighting technology has evolved. Lighting products today offer lower energy consumption, higher energy efficiencies yet giving similar or better lighting quality.

T5 lighting	LED




Magnetic (EM) ballast - 10W

Applications:
	Lamp component
Characteristics:
	Gives rise to control gear losses and energy consumption. Flickering effect of magnetic ballast has negative impact on eyesight.




Electronic (EL) ballast - 5W

Applications:
	Lamp component
Characteristics:
	Control gear losses reduced. Less flickering effect due to electronic ballast.




Circular fluorescent lamp (TLE) with EM ballast & incandescent lamps – 210W

Applications:
	Ceiling lamp in living room.
Characteristics:
	Incandescent bulb: 90% of the power consumed is emitted as heat, not as visible light. EM ballast gives rise to control gear losses Control gear losses contribute to part of energy consumption.




T5 Circular lamp with EL ballast – 43.5W

Applications:
	Ceiling lamp in living room.
Characteristics:
	No incandescent bulb used. Control gear losses reduced. Lux Levels** improved.




Compact Fluorescent lamps (CFL) – 20W

Applications:
	Functional purposes in toilets and storerooms. Decorative use in living room.




Compact Fluorescent lamps – 18W

Applications:
	Functional purposes in toilets and storerooms. Decorative use in living room.
Characteristics:
	Lux levels** improved.

* Electricity tariff rate: $0.3045
** Lux levels: Measurement for brightness. The higher the lux levels the brighter the light.




Magnetic (EM) ballast - 10W

Applications:
	Lamp component
Characteristics:
	Gives rise to control gear losses and energy consumption. Flickering effect of magnetic ballast has negative impact on eyesight.




Electronic (EL) ballast - 3.5W

Applications:
	Lamp component
Characteristics:
	Control gear losses reduced. Less flickering effect due to electronic ballast.




T8 tubular lamp with magnetic ballast – 28W

Applications:
	Usually used for outdoor lighting. Used in bedrooms by Household B.
Characteristics:
	Control gear losses contribute to part of energy consumption. Flickering effect of magnetic ballast has negative impact on eyesight. Glaring to bedroom users.




T5 Circular Lamp with electronic ballast –25W

Applications:
	Bedroom lighting.
Characteristics:
	Control gear losses reduced. Less flickering effect due to electronic ballast . Better light distribution, hence less glare to bedroom users. Lux Levels** improved.




Incandescent lamp – 100W

Applications:
	Functional purposes in toilets and storerooms. Decorative use in living room.
Characteristics:
	90% of the power consumed is emitted as heat, not as visible light.




Compact Fluorescent lamp – 15W

Applications:
	Functional purposes in toilets and storerooms. Decorative use in living room.
Characteristics:
	Longer life span. Lux levels** improved.

* Electricity tariff rate: $0.3045
** Lux levels: Measurement for brightness. The higher the lux levels the brighter the light.
