Answer 6

R-reflector

R20

Question 7

Incandescent bulb type:

Answer 7

BR-bulk reflector

BR 30, BR 40

Question 8

Incandescent bulb type:

Also created in response to EPACT. Reflector shape increases the overall lumen output by redirecting lost light at the sides forward. Used for downlighting.

Answer 8

ER-elliptical reflector

ER30

Question 9

Incandescent bulb type:

Have an aluminum reflector in a parabola shape. Covered with a hard glass lens to control light beams. Use unprotected outdoors because glass can withstand weather. Used for downlighting.

Question 13

Fluorescent bulb type:

These lamps bent into a U-shaped and mounted on a base that house is a ballast. Can be screwed into incandescent luminaires.

Answer 13

CF – compact fluorescent

T4 or T5

Question 14

Hi intensity discharge:

Electric arc is passed through high-pressure mercury vapor that produces ultraviolet and visible light. Primarily blue/green color. Moderately high efficacy at 30–50 lm/W. Life of 24,000 hours. Used for large area overhead lighting in factories/warehouses/sports complexes/streetlights.

Answer 14

Mercury vapor HID lamp

Question 15

High intensity discharge:

Similar to mercury vapor except halides of metal are added to the arc tube. Increased efficiency at 50–100 lm/W. Life of 10,000 hours. Produces a wider, more natural light.

Answer 15

Metal halide HID lamp

Question 16

High intensity discharge:

Produces light by passing an electric arc through hot sodium vapor. Arc tube must be ceramic to resist hot sodium. High efficacy at 80–140 lm/watt. Life of 24,000 hours. Wide variety of color rendition.

Answer 16

High pressure sodium HID lamp

Question 17

High intensity discharge:

Operates like a fluorescent lamp and requires a ballast. Highest efficacy at 150 lm/W. Requires a brief warm-up. To reach full brightness. Monochromatic yellow light seen in parking garages and streetlights.

Answer 17

Low pressure sodium HID lamp

Question 18

High intensity discharge:

Solid-state lighting. Bulbs without a filament, plasma, or gas. Low in power consumption with a long lifespan. Diodes a minute light when connected in a circuit. Run a DC power. Used for flashlights, signage, sustainable lighting, phones, video production.

Answer 18

Light a meeting diode (LED) HID lamp
