Through a prism - ANS A total of six colors(violet blue green yellow orange red) are visible
when passing white light
Standard incandescent light - ANS when a filament operates hotter, its life is shortened,
making it a trade-off between efficiency and lamp life.
Tungsten Halogen Incandescent Lamps - ANS The Halogen gas in the lamp accounts for the
longer life and excellent lumen maintenance
Bi-pin base - ANS Both pre-heat and rapid start Lamps have 2 -pin base at each end.
Single pin - ANS Instant start Lamps have single pin at each end of the lamp
Metal Halide Lamps - ANS Are the most energy-efficient source of white light. They have high
efficiency (80 to 115 LPW), excellent color rendition, long service life (10,000 to more than
20,000 average hours), and good lumen maintenance
NEC Section 410.130(F)(5) - ANS All metal halide Lamps except thick-glass PARs must have a
containment barrier (lens) or Type O with protected socket.

, Color Temp 3000k and lower - ANS Warm in tone and slightly enhanced red and
yellows(Halogen Lamps)
Color Temp 3500k - ANS Moderate tone, producing a balance of warmth and coolness.(metal
Halide Lamps)
Color Temp 4100k and higher - ANS Cool in tone, slightly biased toward blues and greens.
(Fluorescent Lamps)
Color Temp 5000k - ANS Daylight simulating fluorescent lamps
Instant start lamp electrodes - ANS Not preheated. The ballast provide a high voltage (100v
to 1000v) across the electrodes that causes electrons to be emitted from the electrodes.
Electronic instant-start ballast - ANS Lowest system wattage and highest system efficiency.
The lamp life is slightly shorter than with rapid-start ballast.
Constant Wattage Auto transform ballast - ANS An HID type ballast with a circuit that uses
magnetic saturation to maintain better lamp wattage regulation and improved dip tolerance.
Used mainly with mercury and high pressure sodium lamps
Incandescent recessed lighting fixtures - ANS Generate a considerable amount of heat within
their enclosure and are a definite fire hazard if not properly installed
Suspended lighting fixture - ANS Are hung from the ceiling using a chain, aircraft wire, cord,
or metal stem. included in this group are chandeliers and pendant units
NEC article 410 - ANS sets forth most of requirements pertaining to the installation of lighting
fixtures.
NEC article 411 - ANS Covers lighting systems of 30v or less
