Lamp #3 (60 watt incandescent lamp with halogen) produces more light than lamp #1 and the same amount of light as #2, and lamp #3 has longer life than normal incandescent lamps, but produces less light than lamp #4 (23 watt compact fluorescent) or lamp #5 (26 watt compact fluorescent) and lamp #3 won't last as long.amp #6 (40 watt traditional incandescent) and lamp #7 (40 watt fluorescent lamp), both consume the same amount of power, but the fluorescent lamp produces over six times the amount of light for the same electrical cost.
