• B. Bulbs
• C. Tube lights
• D. CFLs

Answer 1

Answer: (A), (D)

The electricity used over the lifetime of a single incandescent bulb costs 5 to 10 times the original purchase price of the bulb itself. Light Emitting Diode (LED) and Compact Fluorescent Lights (CFL) bulbs have revolutionized energy-efficient lighting.Because both CFL and LEDS use very less power as compared to bulbs. CFLs are simply miniature versions of full-sized fluorescents.And LED is a semiconductor device.
