LED Grow Light - First Time Grow

I'm going to be starting my first hydroponic grow soon; have been researching different types of lights and want to select LED lights for my first option and was wondering if anyone could recommend a suitable example or brand to go by. Have a few ideas already, and I will enclose a link to give you an example of a model I'm interested in. If anyone could also provide a reasonable assumption of an attainable yield growing 4 plants under a 600w LED light for a first time grower that would be great thank you. Here is the link
