The 52” combo bar is the largest in our S-Line — it’s one of many high quality yet affordable LED light bars offered here at Project LM. Being a combo bar, this setup offers a lot of versatility for use on any larger vehicle in need of additional lighting. This bar uses a flood beam and spot beam design and emits 24,000 lumens. The flood light beam provides a wide area of lighting, while the spot light is a longer beam. With the combo of both, the projection path is ideal for practically any situation.

You can count on Project LM light bars for all of your light bar needs, and here’s why.

s line LED light bars


  • Maximum quality Cree LED bulbs
  • Highly durable polycarbonate lens
  • Military grade die-cast aluminum housing
  • IP68 rated waterproof, shockproof, and anti-corrosive
  • Military quality breather
  • Limited lifetime warranty



What really sets a quality light bar aside from the rest is the quality of the bulb used in the design. That’s why we only use the top quality Cree LED bulbs in all of our products, including our combo light bars. When you buy your combo beam light bar from Project LM, you won’t have to worry about low-end, generic LED light bars.


aircraft grade aluminum housing

Every Project LM light bar is housed in aircraft grade aluminum heat sink housings. This extremely durable design offers extreme protection of the LED bulbs under the most challenging and extreme use. Our light bar housings have been real life and facility tested to ensure their protection and performance. In addition to the housing, the needed hardware and mounting brackets are stainless steel for long lasting action.


IP68 is the highest rating level assigned to light bars under the international protection standard. This offers a level of rating for light bars (and other products) to advise consumers of what they’re getting. All of Project LM light bars are IP68 rated. This means that all of our light bars are dust-tight (6) and waterproof (8) when immersed in up to one meter of water. Many other light bar brands out there are only rated at IP67 (may not be fully immersed in water) or the even lower IP57 rating (only dust protected, not dust proof).


military standard breather

Project LM light bars utilizes a military quality breathers to prevent moisture build up — this nasty build-up will ruin a light bar. As you drive through different areas and the light bar travels through atmospheric changes, this breather will keep the pressure level from the inside to the outside the same in all conditions. This is a very innovative feature not seen on many light bars on the market today.


We offer an industry-leading limited lifetime warranty against manufacturer defect because we believe so strongly in our products and manufacturing process. If you happen to have any problems with your lighting product, we've got your back. For complete warranty details, visit our warranty page here.
