You can have both flowlights and capsule lights in a composite staff set-ups, though you will need to get the right length tubes.
Flowlights are longer than capsules, so a 2CX tube will be too short for flowlight+capsule+compression connector. We can make you custom 1CFX tubes for $10 fee (1 custom fee for up to 3 tubes). If you would like that, you can make a note in the Customer Notes during checkout that you would like to be able to have the tube hold 1 capsule and 1 flowlight, and we'll send you a payment link for the custom tube length.
You can also use 2FX tubes. These will fit flowlight+capsule+comp connector with a little bit of space in the tube, but you can use this bonus hack, and connect your capsule light to a flowlight with a capsule link!
