What is the guide number?
The guide number of a flash is a measure of its light output. The higher the guide number, the greater the intensity of the flash. More powerful flash units with higher guide numbers have a greater range, have faster recycle times, and make bounce flash more effective. Guide numbers are usually given for ISO 100.
