How Many Lumens in a 100 Watt Bulb?

Answer

If the 100 watt light bulb is an incandescent bulb it gives off approximately 15 lumens per watt. If the bulb is a florescent light bulb, it gives off approximately 50 to 100 lumens per watt. Therefore an incandescent bulb would have 1500 lumens and a florescent bulb would have between 5000 to 10,000 lumens.
