Review on Lightdot 2 Pack LED High Bay Shop Light, 4FT (Large Area Illumination) 265W 38000LM [1000W HPS Eqv.] 5000K Daylight Linear Hanging Light For Warehouse, 10 Lamp Fluorescent Fixture Replacement-ETL by Madison Dickinson

I have been replacing all the lights in our shop with the 2ft version of these. We had one area that we wanted a bit more light in and decided on replacing 2 of the 2ft lights with 2 of the 4ft lights. What a disappointment. The 4ft lights cost 2x as much and give off 10-15% more light than the 2ft versions. Needless to say we were quite disappointed. In the future if we need more light we will just add one extra 2ft light to the area. 3 of the 2ft versions is way more light than 2 of the 4ft versions and cost less.Right now we have around 30 of the 2ft versions in our shop and it's like day light. I would only recommend these for 10ft and higher ceilings.
