I bought a bunch of these lights (China made) and have a few left over. I have (5) 9w (three 3 watt leds) and (4) 10 watt (single led) utility lights.
They are easy to wire up and pretty bright.
the 10 watt light has a 10 watt cree LED and is 2'x2"x2.7" color temp 600k and comes with hardware to attached them together.
the 9 watt light is 2.25x 4.25"x 2.5" color temp 6000k though is slightly less blue as the 10w
I will include stainless hardware instead of the cheap rust prone stuff they came with.
9w = $35 each shipped
10w= $55 each shipped
I have them mounted on my light bar... The outer lights are the 10w and the 2 inner are the 9w
I have a 10w mounted on my kayak rack to light up behind the truck when night fishing
