Multiple choice

Which of the following is NOT a type of energy-efficient lighting system?

  1. LED lighting

  2. Compact fluorescent lamp (CFL)

  3. Incandescent light bulb

  4. High-intensity discharge (HID) lamp
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Incandescent light bulbs are not considered energy-efficient lighting systems due to their low efficiency and high energy consumption.

Multiple choice

Which of the following is NOT a type of energy-efficient technology used in industrial processes?

  1. Variable speed drives (VSDs)
