LED Lighting for Portraits

We are gently moving into using various LED lights for our photo work. Here's a great example of a 500W Daylight LED used for an engagement session. I used a 40 inch shoot thru umbrella or just the parabolic reflector and the barndoors to shoot these using a Lumix GH4 and the 35-100 and the 12-35mm zoom as well as a few primes. Custom WB always using a Lastolite pop up grey card or the Xrite Color Checker white-ish card.
