Question

while shopping for light bulbs, which information would describe the efficiency of the bulb? (1 point)
what color of light is produced by the bulb
how many watts of power the bulb uses
how many lumens, or brightness, the bulb has
how much the bulb costs

Explanation:

Light bulb efficiency is about how well it converts electrical energy into light. Lumens measure brightness (useful light output), and watts measure power (energy input). Efficiency is related to the ratio of lumens (output) to watts (input). Color of light and cost do not directly relate to efficiency.

Answer:

how many lumens, or brightness, the bulb has
