Not even half of the LEDs light up upon installation. Super bummed. Edit. Got a new one and sent the other back. Holy crap it's so much brighter than the other lights I've had. Used it duck hunting and had several comments on how bright it was. Really nice color depth to the white light. The spot and flood combo was really nice.

Very bright !

Size: 2Pcs 7.6Inch Light Bar, Size: 2Pcs 7.6Inch Light Bar

I haven't had a chance to use them on the river yet. I just finished installing them. They were easy to install and they are very bright ! My home is at the end of a cul-de-sac and with my boat parked in the garage I can light up the house on the other side of the street. I'll need to adjust the lights when I'm on the river. The mounting hardware supplied seems like it will be an easy task.
