There are tons of different possibilities to set up your lights for your bullet-time shots. Here's an overview of the differences between using constant or strobe lights.
Constant lights
This is the best option if:
- You want to have the same visual for the user experience and the end result
- You're doing interval or jump-and-freeze triggering
- Your cameras are in perfect conditions and are triggering with great accuracy

Tips:
- Make sure that your constant lights are not flickering. Otherwise, you'll see flickering and trigger glitches
- Try to match your white balance with your lights for greater colors
Strobes (flash, popup flash)
This is the best option if:
- You need the best accuracy to freeze your subject
- You're on a budget (you can get away with a single popup flash on one of the cameras
- Your cameras are getting old (lazy shutter) and you start to see trigger glitches when using constant lights
Some examples:
- Popup flash on the first and the last cameras: https://www.instagram.com/p/BucrOIBgiIM/

Tips:
- Always shoot with a shutter speed of 1/60s when using strobes
