    Brighter than my headlights on bright!
    Color: 26Inch Light White
    This Nilight 26 inch 540 watt 50,000 lumen Triple Row Driving light is the brightest light I've ever had on my truck. I bought a kit to mount the light to my Grill Guard, just above the bumper. I can see deer just like daytime, at least two blocks before I get to them. I've never seen a light bar as bright. There are no cons if you ignore the fact that it comes without a wiring harness. I definitely recommend this light bar!

    Satisfied customer!

    First, the picture isn't great, but I didn't intend it for the review. I'm really impressed with the quality and brightness of this light for the price! Installation was easy and straightforward. If you can do some basic work with hand tools, you can install this light in about 30 minutes, including wiring. I like the functionality of having the different light modes, although I typically just use the bright white setting. Some people complained about water getting into their light, but I haven't had any problem with water resistance after several months (including rain, snow, off-roading, and spraying it down with high pressure at the car wash. It fit perfect, just make sure you pay attention to the measurements before you order.

    Great performance but low grade material.

    I want to give it 5 stars but I can't because: The light bar is extremely bright and they go a great distance. I am very satisfied with how much it puts out. 5 out of 5 stars for its performance. HOWEVER nilight seems like they're starting to go cheap with their build material. 2 out of 5 stars for that. I have added photos of the older material vs new material for reference. Their old material is 3.3mm thickness compared to their new material at 2.7mm thickness. And that's for the mounting brackets and the light bar housing. It doesn't seem like .6mm would be a big deal but it's noticeably less rigid. Hand tight started bending the metal. Great product for sure but build material is low grade. Not trying to knock them, I love nilight products and will keep using them but it seems like they trying to save money by cutting weight which makes it less rigid. Dings and scratches come easily now. It worries me a little bit if it can take the abuse of vibrations over time from driving around now.

    It will light up your life
    Color: 26Inch Light White w/Wiring Harness
    I only got to use them once before my jeep was totaled. They’re super bright. Great build quality. It survived taking a header down a mountain side and rolling 4 times. When the jeep was recovered, the light bar still worked!!

    Great light - very bright.
    Color: 26Inch Light White
    Installed on a Bronco. It wasn't designed for a Bronco, but I was able to mount it after a trip to hardware store and some minor modifications. The quality of the light itself seems good. Time will tell how long it lasts. It definitely lights up the road and is worth the price.
