Review on Powerful 18W LED Flood Light With 60 Degree Spread For Off-Road, Construction, Tow Trucks, Marine, And Utility Applications - LAMPHUS CRUIZER 4 With IP67 Rating by Thomas Unruh

The lights are bright and do their job, but the mounts could use a little tweaking. The block that you mount to the light is attached with an allen screw. If you tighten it down all the way it prevents complete rotation of the half moon swivel that rotates the light up and down. I ordered two of the 4" work lights and two of the 6" headlights. The 4" were not as bad as the 6" to get right. I wound up using a washer as a spacer between the block and the light so that I could get it tight. Very little instructions were included. As with most things, more money spent gets more quality control.
