A florescent lamp is stated to be "seasoned" whilst: - ANS-a clean non-flickering operation takes
place
a lamp bears the code designation T10 the code indicates - ANS-tubular bulb 1(1/four) diameter
a lamps designation which states H36 is a _________ lamp - ANS-mercury vapour
a mild supply with a excessive colour rendering index CRI will: - ANS-purpose the least
emphasis or distortion of shade
an incandescent lamp is rated at 130V, a hundred w is hooked up to a 120V supply, how will its
mild and life be affected? - ANS-light output down life multiplied
coefficient of utilization - ANS-percent of the unique lamp lumens that reach the task area to
produce illumination.
Diffuse glass - ANS-reduces the brightness of the light source by efficaciously growing the
surface location of the bulb.
Elements that make a contribution to exceptional of light - ANS-glare diffusion shade
4 essential factors governing the visibility of a project: - ANS-size brightness comparison time
generally the HID lamp with the longest restrike time is the - ANS-steel halide
typically the mild source as a way to produce the highest colour rendering is - ANS-an
incandescent lamp
generally, for the identical form of fluorescent lamp, which of the subsequent conditions could
require the highest starting voltage?
-largest diameter, longest length tube
-smallest diameter, shortest period tube
-smallest diameter, longest length tube
biggest diameter, shortest period tube - ANS-smallest diameter, longest duration tube
excessive stress sodium full light and restrike time. - ANS-3 to four start, 1 minute restrike
, excessive pressure sodium lamp lifestyles? - ANS-24000 hours
how long do ballasts ultimate? - ANS-12 to 15 years
low stress sodium lamps are? - ANS-the most efficient lamp source efficacy of two hundred
lumens per watt
Luminaire Efficiency - ANS-percentage of total lumens emitted by using the luminaire compared
to overall lumens generated by using the lamp on my own.
Mercury vapour lamp complete light output and restrike time. - ANS-three to 7 minutes start,
four to six restrike
mercury vapour rated existence - ANS-24000 hours
Metal halide lamp complete mild and restrike time. - ANS-five to 7 minutes begin, 15 minutes
restrike
metal halide lamp life - ANS-15000 hours
most commonplace used lamp base - ANS-edison base
most incandesecent lamps radiate approximately ________ % of their general power enter as
light output. - ANS-10%
of the lamps indexed that usually has the longest lifestyles can be :
-low strain sodium lamps
-excessive strain sodium lamps
-incandescent lamps
-fast start fluorescent lamps - ANS-high pressure sodium lamps
rated lifestyles of most fluorescent lamps is? - ANS-7500 to 20000 hours
the benefit that tungsten-halogen lamp has over a popular incandescent lamp is:
- it's miles less high-priced than a incandescent lamp
-the filament temperature isn't as warm
-it has a higher color rendering index
-it has a better rated life - ANS-it has a excessive rated lifestyles
