I like Lithonia lighting worklight t8 fixture. I modify it by using the stock ballast to overdrive 1 of the lamps, and buy another ballast to overdrive the other. I line the reflector with mylar to increase reflectivity. a 32 watt t8 lamp can be overdriven to 54 watts to put out about 5000 lumens. This modified fixture will deliver close to 5000 lumens per square foot, with a nice reflector, which will grow high light requiring plants, such as roses which I grow. I do not grow pot. Google search "t8 overdriving" for more details.
