At Project LM, you’ll discover an extensive selection of light bar options in our high quality and affordable products. This 52” curved LED light bar offers a ton of utility for various uses and applications. A very appealing aspect of this line is that they are combo lights — making them the best of both worlds when it comes to lighting. They project a very long spot light beam as well as a nice wide flood beam and emit 24,000 lumens. The combination gives you the ultimate in visibility.

This curved combo light is very useful when mounted to any large vehicle in need of a better lighted path. Thanks to the larger beam projection area, these combos lights are extremely popular amongst anyone who travels off the beaten path. Project LM light bars are facility tested as well as real life tested to prove their continuous performance. Here’s why Project LM lighting solutions are the best for your vehicle.

military grade breather

The military grade breather used on our light bars is extremely innovative. It is made to prevent moisture build up that will ruin your light bar sooner rather than later. This is achieved by balancing the pressure from the outside to the inside of the bar. This is extremely important as the bar goes through atmospheric changes. The air breather we use isn’t a feature you’re likely to see on most other light bars out there — you’ll always get it with Project LM light bars.


Light bars are assigned ratings by international protection (IP) for consumer education, and IP68 is the top light bar rating. What the IP68 rating means is that Project LM light bars are both dust-tight (6) and waterproof (8) when immersed in 1 meter of water. Many other lighting brands are rated at a lower level IP67 (won’t work after being immersed in water) or the lower IP57 (only dust protected, not dust proof).


c line housing

Every LED light bar we carry at Project LM, including our C-Line combo bars, is housed in an aircraft quality housing. Our housings are made of aluminum heat sink and can withstand extreme use. Additionally, the included hardware and mounting brackets are stainless steel to prevent corrosion — while also being extremely durable to support the light bar.


An indicator of quality and performance in LED light bars is the bulbs used. Cree light bulbs are the best made bulbs available when it comes to LED lighting. At Project LM, we use Cree light bulbs in all of our LED light bars — we never use low quality generic bulbs in our products!


At Project LM, we stand behind the quality of our products. That's why we offer an industry-leading limited lifetime warranty. For complete details, visit our warranty page here.
