The physical components of a light fixture include the lamp, ballast, and lens.
VERIFIED AGAINST THE SOURCE
“A light fixture consists of a lamp, a ballast, and a lens.”
— CDSE — Exterior Security Lighting (PY109.16) Student Guide ↗03What is the role of a ballast in a light fixture?
A ballast is used to obtain the necessary circuit conditions of voltage, current, and waveform for starting and operating the light source.
VERIFIED AGAINST THE SOURCE
“A ballast is a device used with an electric discharge light source to obtain the necessary circuit conditions of voltage, current, and waveform for starting and operating.”
— CDSE — Exterior Security Lighting (PY109.16) Student Guide ↗04How does low-level lighting benefit security forces?
Low-level lighting allows security forces to see for long distances and minimizes their visibility to intruders.
VERIFIED AGAINST THE SOURCE
“Low level lighting must be used on security forces to minimize their visibility to intruders.”
— CDSE — Exterior Security Lighting (PY109.16) Student Guide ↗05What is light trespass and how can it be minimized?
Light trespass occurs when light from one area spills over into an adjoining area, and it can be minimized by using shielded light fixtures and avoiding over lighting areas.
VERIFIED AGAINST THE SOURCE
“Light trespass can cause interference with the security of the adjoining area.”
— CDSE — Exterior Security Lighting (PY109.16) Student Guide ↗06What is the significance of vertical illuminance in security applications?
Vertical illuminance is important for identification at security checkpoints, as it allows security personnel to see faces clearly.
VERIFIED AGAINST THE SOURCE
“Vertical illuminance on people's faces is important for identification at security checkpoints.”
— CDSE — Exterior Security Lighting (PY109.16) Student Guide ↗07What is the recommended action when light fixtures are in poor condition?
Light fixtures that are in poor condition should be replaced, especially if they create hazardous situations.
VERIFIED AGAINST THE SOURCE
“If the light fixtures are in poor condition, especially those creating hazardous situations, they should be replaced.”
— CDSE — Exterior Security Lighting (PY109.16) Student Guide ↗08What type of lighting should be used to keep security forces in relative darkness?
Continuous lighting with glare projection should be used to keep security forces in relative darkness.
VERIFIED AGAINST THE SOURCE
“With glare projection, lamps are mounted on poles inside the protected area and directed outward to make it difficult to see inside the area.”
— CDSE — Exterior Security Lighting (PY109.16) Student Guide ↗09What is the average rated life of incandescent lamps?
The average rated life for incandescent lamps ranges from 750 to 3,500 hours.
VERIFIED AGAINST THE SOURCE
“The average rated life for incandescent lamps is 750 to 3,500 hours.”
— CDSE — Exterior Security Lighting (PY109.16) Student Guide ↗10What is the main consideration for lamp efficacy?
Lamp efficacy refers to the amount of light produced by a light source for every watt of energy consumed.
VERIFIED AGAINST THE SOURCE
“Lamp efficacy or efficiency refers to the amount of light produced by a light source for every watt of energy.”
— CDSE — Exterior Security Lighting (PY109.16) Student Guide ↗11What type of light fixture is used to control light trespass and direct glare?
Cut-off light fixtures are used where control of light trespass and direct glare is important.
VERIFIED AGAINST THE SOURCE
“Cut-off light fixtures are used where control of light trespass and direct glare is important.”
— CDSE — Exterior Security Lighting (PY109.16) Student Guide ↗12What is the purpose of using solid state lighting (SSL) in exterior security?
Solid state lighting (SSL) is used for its efficiency and long lifespan compared to traditional lighting technologies.
VERIFIED AGAINST THE SOURCE
“The most energy efficient technologies are solid state lighting (SSL) light-emitting diode (LED) and induction lighting systems.”
