The Victorian commercial sector spends more than $550 billion on lighting each year.  Lighting is likely to be a major part of your organisations energy bills and some simple changes could save your organisation thousands of dollars per annum.

LAMP EFFICIENCY AND LIFE
Lamp life and efficiencies vary dramatically. The table below gives an indication of the efficiency, lamp life and power consumption from a range of lamps.

Type	Wattage	Voltage	Price $	Lumens/watt	Life (Hrs)
Incandescent Lamp	15 - 2000	Various	Various	7-15	1,000
Low Voltage Tungsten Halogen	10, 20, 35, 50	12	3	12-24	2,000
High Voltage Tungsten Halogen	50 - 2000	240		30	2,000
Compact Fluorescent	8 to 24	240	5 to 20	44-80	6,000 – 15,000
Conventional Fluorescent	20 & 40	240	5	70-100	7,000-20,000
High Efficiency Tungsten Halogen	35 & 50	12	10 to 15	20-45	5,000
Micro Fluorescent	7 & 9	240	20 - 25	52-72	12,000
LED's	Up to 5	12	30 - 100	10-100	Up to 50,000

Note 1: Lumens per watt measures the efficiency of the lamp. (The larger the number, the more efficient the lamp).

 

INCANDESCENT LAMPS
Incandescent lamps or bulbs are the most commonly used type of lighting. They are inexpensive to buy but their running costs are high.

The Australian Government has started to gradually phase out all inefficient incandescent light bulbs.

The first stage of the phase-out plan was an import restriction on inefficient incandescent general lighting service (GLS) light bulbs used for general lighting purposes from 1 February 2009. Incandescent lamps are called:

·        GLS 100w                 

·        GLS  75w                  

·        GLS  60w                  

·        GLS  40w

 

TUNGSTEN HALOGEN LAMPS
Halogen lights are also a type of incandescent lamp. They are more expensive to buy but last up to two thousand hours. They can be either 240V bulbs, which are usually tubular and often used in up lighters and outdoor floodlights, or low voltage bulbs typically used in down lighting. All halogen lamps require special light fittings.  Types of Halogen lamps include:

·        Halogen Lamp MR16 Lamps 35w

·        Halogen Lamp MR16 Lamps 50w

 

FLUORESCENT LAMPS
Fluorescent lamps are the most energy efficient form of lighting for businesses. They work by causing a phosphor coating on the inside of a glass tube to glow. Different types of phosphor give different colour light.  Although more expensive to buy, they are much cheaper to run and can last up to twenty thousand hours. Lamps in this range are:

• T5 28 Watt Linear Fluorescent Tube
  High efficiency T5 28 Watt Linear Fluorescent Tube. A highly effective Fluorescent Tube which produces a bright, natural looking light. Uses 25% less energy than conventional T8 Fluorescent Tubes. Incorporates a slimline design, measures only 16mm in diameter. 12,000 hours average lamp life. Available in a range of colour temperatures.

• T8 Fluorescent Tube
• T12 Fluorescent Tube
