Questions and Answers 100% Solved
Through a prism - ✔✔A total of six colors(violet blue green yellow orange
red) are visible when passing white light
Standard incandescent light - ✔✔when a filament operates hotter, its life is
shortened, making it a trade-off between efficiency and lamp life.
Tungsten Halogen Incandescent Lamps - ✔✔The Halogen gas in the lamp
accounts for the longer life and excellent lumen maintenance
Bi-pin base - ✔✔Both pre-heat and rapid start Lamps have 2 -pin base at
each end.
Single pin - ✔✔Instant start Lamps have single pin at each end of the lamp
Metal Halide Lamps - ✔✔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) - ✔✔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 - ✔✔Warm in tone and slightly enhanced red
and yellows(Halogen Lamps)
Color Temp 3500k - ✔✔Moderate tone, producing a balance of warmth and
coolness.(metal Halide Lamps)
Color Temp 4100k and higher - ✔✔Cool in tone, slightly biased toward
blues and greens. (Fluorescent Lamps)
Color Temp 5000k - ✔✔Daylight simulating fluorescent lamps
Instant start lamp electrodes - ✔✔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 - ✔✔Lowest system wattage and highest
system efficiency. The lamp life is slightly shorter than with rapid-start
ballast.
Constant Wattage Auto transform ballast - ✔✔An HID type ballast with a
circuit that uses magnetic saturation to maintain better lamp wattage
