Units of Measurement
• Input Power – Watts
• Light Output – Lumens
• Efficacy* (of light source) – Lumens per watt
• Efficiency (of a light fixture) – Stated as a percentage
• Light Levels (at work plane) – Footcandles
*
The amount of energy service or useful energy delivered per unit of energy input. Often used in reference to lighting systems, where the visible light output of a luminary is relative to power input; expressed in lumens per Watt; the higher the efficacy value, the higher the energy efficiency

Advantages of Incandescent
• Inexpensive
• Available Everywhere
• User Familiarity
• Easily Dimmed
• Good Color (CRI)

Disadvantages
• 20% of the energy consumed is converted to light, the rest to heat
• Short lamp life – 850-1000 hours
• Low efficacy rating (lumens per watt)
• They will be outlawed in the future

Halogen
• A more efficient incandescent source
• Good “point source” illumination
• Longer Lamp Life – regenerative cycle
Note: Regenerative cycle – As the filament heats up and tungsten particles are released they combine with bromine and are redeposited onto the filament when the lamp is turned off.

Linear Fluorescent
How do they Work?
• A ballast is needed to start the lamp and then it quickly switch over to the operation mode
• An electric arc is passed between cathodes in a glass tube which excites mercury and other gasses and produces UV radiant energy. A phosphor coating on the tube then convert this energy to visible light.
• Different color temperatures, “warm white” through “cool white are achieved by adjusting the phosphor coating

Compact Fluorescent Lamps

Advantages
• Available in many shapes and size, wattage and versions
– Self Balasted
– Replaceable lamp versions
– New GU24 Sockets
• Last 10,000 hours or longer
• Use 70% less energy than standard incandescent
• High CRI (80+)
• Price and quality is improving all the time

Disadvantages
• Still more expensive than incandescent
(first cost)
• Not as user friendly as incandescent
– Most can’t be dimmed or used with photosensors
– Usually shorter lamp life is from over heating (recessed cans, etc.)
• Requires disposal(all contain a little mercury)
