A 15 watt LED light is equivalent to a 100 watt incandescent light bulb.
15 watt LED light bulbs should be as bright as a 100 watt incandescent light bulb and produce the same amount of light but only use 15 watts of electricity instead of 100 watts.
The 15 watt LED light bulb will be cheaper to operate than a 100 watt incandescent light bulb and produce the same amount of light.
A 7 to 9 watt LED is equivalent to a 60 watt incandescent light bulb.
Watts are a measurement of power, describing the rate at which electricity is being used at a specific moment.
For example, a 15-watt LED light bulb draws 15 watts of electricity at any moment when turned on.
A 100 watt light bulb would draw 100 watts of electricity and costs more to run.
