Works very well with few minor flaws, DC plug sits badly and can be easily taken out, so you have to figure out how to fix it during shooting, especially whey lighting a ceiling or a high positioned object. Secondary, and that's a bigger problem, the lamp gives a certain magenta tint on pictures, not critical, but visible still. Yes, that's bad for professional filming. The battery charger isn't powerful, so charging a battery takes time. Anyway for such a price works great. Thanks.
