Our Commercial Luminaire Model AGA1 is
a beautiful option to top our decorative lamp posts, wall and decks lights,
and courtyard lighting. Made from the same cast aluminum with black polyester
powder coat finish, this fixture will provide years of low maintenance service.
High Intensity Discharge Lighting (HID) lamps (light bulbs) are arc type light
sources originally developed for outdoor and industrial applications. Their
relatively long life reduces maintenance costs and their high efficacy minimizes
energy usage, thereby lowering the overall operating cost of an HID light source.
HID lamps are best for applications where they are on for eight to ten hour
intervals and are not switched on and off intermittently.
Lamp maintenance depends in large part on the rated lamp life (how long the
lamp will last before it must be replaced). Lamp life is expressed in hours
and is based on laboratory testing.
Typical ratings are as follows:
Incandescent - 750 - 1,000 hours
Metal Halide - 10,000 hours
High Pressure Sodium - 24,000 hours
The efficiency of a lamp depends on its efficacy. Efficacy relates to the amount
of light produced (lumens) to the amount of electricity used (watts). The higher
the lumens per watt (LPW), the higher the efficacy. In other words, it is better
to get the amount of light you want by using less electricity.
Typical lamp efficacies are as follows:
Incandescent - 20 LPW
Metal Halide - 90 LPW
High Pressure Sodium - 120 LPW
The ability to see colors properly is a key aspect of light quality. Light
sources vary in their ability to accurately reflect true colors. The Color Rendering
Index (CRI) is a scale of 0 to 100 and is used to compare the effect of a light
source on the color appearance of its surroundings. The higher the CRI, the
truer the appearance of colors under that light source. The lower the CRI, the
more difficult it is to distinguish one color from another. A rating of 100
would be closest to natural light while a rating of zero would be like watching
a black & white television.
Typical CRI ratings are as follows:
Incandescent - 100 CRI
Metal Halide - 65-70 CRI
High Pressure Sodium - 22 CRI
Auxiliary equipment such as ballasts, starters, capacitors, and pulse rated
sockets are required for proper operation of HID lamps. Ballasts must match
the specific type and wattage of the lamp and are available in a variety of
voltages. Specs: Height - 38"; Width - Plain
(16"), W/Oval Band (16"), W/Band and Vertical Arms (17.25").
Available in Plain, W/ Oval Band, W/ Weave Band and Vertical
Arms, and W/ Oval Band and Vertical Arms.
