Two 50-watt bulbs do NOT produce the same light as one 100-watt bulb. Light output (lumens) doesn't scale linearly with wattage due to efficiency curves - a single 100W bulb typically produces more lumens than two 50W bulbs combined.

Buzz Aldrin (Edwin Eugene Aldrin Jr.) was the second person to walk on the moon on July 20, 1969, stepping onto the lunar surface about 19 minutes after Neil Armstrong first set foot.

This is a duplicate of question 14162. Two 50-watt bulbs do NOT produce the same light as one 100-watt bulb due to non-linear efficiency scaling.

A compact fluorescent (CFL) bulb typically lasts about 8,000-10,000 hours, which is roughly 10 times longer than a 750-hour incandescent. CFLs are more efficient and generate less heat, contributing to their longer lifespan.
