I bought this RGB portable light for correcting car paintwork. It does more than I expected. Easy to use and multifunctional. You can adjust white color temperature and brightness. The light is so bright that it even exceeds the light of an LED lamp by 5000 lumens. Also, I use it on my drywall project and I don't worry about the cord because the portable RGB light has a built-in high-capacity battery. A funny thing is that I also use it as a power bank to charge my phone.
