Project LM offers a full line of high quality, yet affordable, LED light bars. Here, you’ll find a superior lineup of light bars, including these versatile 50” combo beam light bars. They offer the best of both worlds as they project a flood beam, spot light beam, and emit 23,040 lumens. The flood beam gives you a wide lighted area, while the spot beam offers a concentrated and long projection path.

These combo lights are perfect for use on any larger vehicle in need of more lighting. Here’s why you should count on Project LM for all of your light bar needs.

s line light bars

  • Uses extremely durable polycarbonate lens
  • Military grade die-cast aluminum housing
  • Limited lifetime warranty
  • IP68 rated waterproof, shockproof, and anti-corrosive
  • Military quality breather



Where you’re really going to note the difference in quality and performance when it comes to light bars is the type of bulbs used. In all of our lights, including the LED combo beam bars, only Cree LED bulbs are used. When you buy your light bar from us, you’ll always get the best materials and won’t have to settle for low-end, generic bulbs.


aircraft grade aluminum housing

Each Project LM light bar is housed in high end, aircraft grade aluminum heat sink housing. This highly durable housing offers extreme protection in the most challenging conditions. These housings have been facility and real life tested to ensure performance. In addition, included with the combo light bars are stainless steel hardware and mounting brackets.


The international protection standard offers a level of rating for light bars (and other products) so consumers know what they’re getting. All of our light bars are IP68 rated — this is the highest rating for light bars. This means that all of our light bars are dust-tight (6) and waterproof (8) when immersed in one meter of water. Other brands available are only rated at IP67 (cannot be fully immersed in water) or an even lower IP57 rating (they’re not dust proof, only dust protected).


We believe so strongly in our products and manufacturing process that we're offering an industry-leading limited lifetime warranty against manufacturer defect. Check out our warranty page here for more information.


military grade breather

The military quality breathers used on Project LM light bars prevent moisture build up — this detrimental build-up will ruin a light bar sooner or later. As your vehicle moves and the light bar travels through atmospheric changes, this breather will keep the pressure consistent from the inside to the outside in all conditions. This is a truly innovative feature not seen on many light bars.
