There was a little more space on the light deck to add two more LED flat panels. I did this one for a customer and will continue to offer it. Looks great and offers a lot of light in 3 shades of white, and best of all, can be dimmed to a light glow. At full output, I measured a useage of 49 watts! That is a lot of light for very little energy. My new kayak lights are built better than ever. Sold as a kit also.
