One of the things I learned while reading this article is that professional studio light sources mostly have two categories. The two categories are that you can get a power pack or get a kit with a flash head. The power pack has small flash tubes with an emit light at a high voltage. There are also some have multiple head flash. There are also moonlights that compact substitutes for a power pack. It is easy to control the power pack because it has a lot of controls. One thing that I learned was that if you are shooting outside it is complicated with the modifier setups. If the symmetric power packs need to be split equally between multiple flash heads.
The flashlights flash in one direction to give the two lights control. monolights can really come in handy because it can help when you want a freeze action. Even though I learned that it could be difficult to shoot outside. They could overcome the sun or there could be light loss which will be caused by modifiers. Also, an advantage with be having head and pack systems. There was a zoom reflector and will provide the ability to attach a honeycomb grid and will also be focused spread. There also has to be some silver-lined umbrellas that will focus and give it reflected light.
