Aputure MC 4-Light Kit
Excellent for in-car filming or lighting small spaces; this kit of 4 are bright but very compact, producing 400 Lux at 0.5m, and a BiColour range of 3200-6500K as well as full RGB.
Each light is rechargable so no need for additional power sources or batteries, and can last up to 15 hours (on low brightness, 2 hours on maximum). It is also USB-C so if you did need it to last for longer you can attach it to a power-bank or something capable of providing USB power output to keep it going for much longer.
Each light is also magnetic, and roughly the size of a credit card, so when space is a premium, these fit in to the smaller of spaces.
Handy Qi Wireless Charging feature within it’s carry case, so charging up again between your shoots is as easy as it gets.
