    PARABOLIC ALUMINIZED REFLECTOR (PAR) LAMPS:

    ALLOW DIRECTED BEAM CONTROL EITHER AS A SPOT (NARROW) OR A FLOOD (WIDE).

    PAR LAMPS ARE CONSTRUCTED OF HARD GLASS FOR EXTERIOR USE.

    INTERNAL REFLECTOR (R) LAMPS:

    ALSO ALLOW DIRECTED BEAM CONTROL, EITHER AS A SPOT LIGHT OR FLOOD LIGHT.

    THEY CONSTRUCTED OF SOFT GLASS AND ARE INTENDED FOR INTERIOR USE.

    COLOR RENDERING CHARACTERISTICS:

    INCANDESCENT LAMPS PRODUCE A WHITE LIGHT WHICH IS WARMER THAN SUNLIGHT, RICH IN YELLOWS & REDS, WEAK IN GREENS & BLUES.

    LOWER WATTAGES TEND TO BE WARMER & HIGH WATTAGES COOLER.

    DIMMED LAMPS GIVE OFF A YELLOW-RED LIGHT.

    COLOR RENDERING CHARACTERISTICS:

    INCANDESCENT SOURCES PRODUCE LIGHT WHICH IS VERY FLATTERING TO SKIN TONES.

    THE CORRELATED COLOR TEMPERATURE OF STANDARD INCANDESCENT LAMPS IS BETWEEN 2600 AND 3000K.

    EFFICACY:

    INCANDESCENT SOURCES HAVE VERY LOW EFFICACY, BETWEEN 15 AND 25 LUMENS PER WATT.

    EFFICACY INCREASES WITH WATTAGE.

    ADVANTAGES:

    ACCURATE COLOR RENDITION.

    LAMP LIFE IS INDEPENDENT OF THE NUMBER OF STARTS.

    INSTANT START & RESTART.

    SIMPLE & INEXPENSIVE DIMMING.

    LOW INITIAL & REPLACEMENT COSTS.

    COMPACT SIZE.

    INEXPENSIVE FIXTURES.

    FOCUSABLE AS A POINT SOURCE.

    REQUIRES NO BALLAST.

    DISADVANTAGES:

    LARGE NUMBER OF SOURCES ARE REQUIRED BECAUSE OF THEIR LOW EFFICACY.

    HIGH ELECTRICITY COSTS.

    HIGH HEAT GAIN FROM LIGHTING.

    SHORT LAMP LIFE RESULTING IN HIGHER MAINTENANCE COSTS.

    TUNGSTEN-HALOGEN LAMPS:

    THE FILAMENT IS HOUSED WITHIN AN INNER QUARTZ ENVELOPE WHICH CAN TOLERATE HIGH OPERATING TEMPERATURES.

    SLIGHT BETTER CRI.

    EXTENDED LIFE (2000 TO 12000H).

    GREATER LUMEN MAINTENANCE.
