Bob's answer is correct except it is not necessarily a 'Flood'
In addition the PAR # refers to the diameter in 1/8"
e.g. PAR38 is 4.75" in diameter
PAR30 is 3.75" in diameter
The 'spread' of the light is a function of the lens of the bulb
- Very Narrow Spot
- Narrow Spot
- Medium Flood
- Wide Flood
- Very Wide Flood
These lens classifications are more for theatrical lighting but check the bulb package it should at least say 'Spot' or 'Flood'
