What do CRI and TLCI numbers mean?

They are attempts to score how accurately a light renders colour compared with a reference source, with higher being better and figures in the high nineties being good. They are imperfect, particularly for LEDs, and two fixtures with the same score can still render skin differently. Use them to rule out poor fixtures rather than to choose between good ones.

Can an RGB light produce accurate white?

It can produce white, and better fixtures include dedicated white emitters alongside the coloured ones precisely so that it is accurate. What it cannot do is match a bi-color fixture of the same wattage for output. If you are buying one light and it has to do everything, look for an RGBWW design and accept the lower output.

Do I need mains power or will batteries do?

Both are usually options, and the answer depends on run time. A 60 watt fixture on a V-mount cell drains it quickly, and a bright key light run all day is a mains job. Batteries make sense for fill, accent and location work where you cannot run cable. Work out watt hours needed before assuming a battery will cover a shoot day.

Is one light enough to start?

It can be, if you use the room. A single fixture as a key, with a reflector or a white wall as the fill, produces a perfectly good interview. The second fixture people usually want is not a second key but a background or hair light, which is where an RGB unit earns its place.

Bi-Color vs RGB LED Video Light (2026)

Short answer

For lighting people, a bi-color fixture puts more usable light on the subject for the same wattage and the same money, because it is not spending output through colour filtering. RGB earns its place when colour is the point: a background wash, a practical you want to match, a police light gag. Most working kits end up bi-color for key and fill, with one RGB fixture for accent.

The light is going on a face. Bi-color fixtures dedicate all their emitters to white output, so at a given wattage you get more light on your subject and typically better skin rendition. When you are trying to overpower a window or push through a diffuser, that difference is the whole ballgame.

Check the colour rendering figures the maker publishes rather than the wattage alone. A high output fixture with poor rendering makes skin look wrong in ways that are painful to correct in the grade. Also match colour temperature between your fixtures, because two lights at different temperatures on the same face is a harder problem than either light being slightly off.

You light backgrounds, you need to match a coloured practical already in shot, or you shoot content where colour is part of the look. An RGB fixture replaces a bag of gels and can be dialled in from the app while you watch the monitor, which is far faster than taping gel to a barn door.

Do not expect it to be your key. Producing white light from coloured emitters costs output, so an RGB fixture rated at the same wattage as a bi-color one puts noticeably less light on a face. Treat RGB as the accent and effect fixture and buy white output separately.
