Nanlite PavoTube II 30XR RGB LED Pixel Tube Light (4′, 2-Light Kit)

This is the 2-light kit, which is the sensible way to buy tubes: one is an accent, several are a lighting plan. A tube gives you a long, narrow source instead of a point. That makes a soft line down a face or along a product, and because it looks like a practical it can sit in the frame rather than outside it.

It covers 2700-12,000K, so it matches a tungsten practical at one end and daylight through a window at the other without gels.

CRI 97 and TLCI 98 is what keeps skin tones honest — below about 90 they go sallow or green and grading never fully recovers them.

Full RGB means background colour and effect work without gels. It runs off its own internal battery, so it can be taped, clamped or hand-held anywhere in the set without a cable back to the wall.
