Lighting
The past
The future
Lamp development and efficiency
Incandescent
•
•
•
•
•
More a heater than a light
Approx. 97% heat , 3% light
Short life span
Cheap to buy
Expensive to run
Halogen
•
•
•
•
Roughly 95% heat , 5 % light
Excellent colour rendering
12V, 24V and mains voltage,
Popular on mass market since
early ‘90s
Linear fluorescent
T13
T8
T5
• Available in different
colour temperatures.
• T13-T5- older , to
recent technology
• Relatively efficient
• Contain mercury
Colour temperatures
Different light types
have different ‘colour
temperatures’
The eyes behave
differently with different
colours.
Ie- Cool white is a better
choice for reading
lamps, as contrast is
sharper.
Compact Fluorescent
• 4 X more efficient than
incandescent
• 2-3 x more efficient than
halogen
• More reliable than those
mentioned
• Not easily dimmable
• Contain Mercury
Cool white, and warm white
• Carefully select correct lamp for each unique situation
LED- Light emitting diode.
•
•
•
•
•
•
•
Efficiency up to 50%**
Extremely long lasting (if good quality, and if heat is dispersed)
Relatively expensive for quality fittings.
Price is plummeting
Over long term a cheaper system than any other light form
Much safer disposal
Lamps must be kept cool
Light fitting design
Not all efficient lamps come with satisfactory
fittings….
• How is inefficiency guaranteed in this fitting?
Relative life span of lamps
(This comparison relates to good quality
lamps)
•
•
•
•
•
Incandescent lamps- 1-2 000 hours
Halogen lamps- 2-8 000 hours
CFL- 5-10 000 hours
Fluorescent Tubes – 4000-10 000
LED- 30-50 000
‘Real-time’, (home) energy monitors
• Live energy and cost
monitoring
• Like having a ‘speedo’ for
your house
• Can be connected to
Google for enhanced
monitoring and details
Pic: Current Cost
Energy, or power meters
• Excellent for measuring
actual consumption of
any plug in appliances
• Can also enter cost of
energy to calculate
running costs over any
nominated period
• Great for single use
costs- i.e. dishwashers,
or long term costs- i.e.
fridges.
