Who this is for
You’re bombing down a dark desert highway when a coyote darts across the road — spot beams catch it at half a mile. Now you’re picking through a rocky trail at camp — flood beams light up the roots at your tires. The beam pattern you choose determines which scenario you’re ready for.
If you spend your time on highways or overlanding through open areas, lean toward a spot beam. Owners favor spots for reach because “a set of spotlights are going to shoot further down the road” where you might hit roaming animals, and a pair can throw visibility over a half mile on open desert.
Technical trails, campsites, or work sites call for a flood beam. Flood patterns illuminate a large, wide area within a short distance, which helps you see rocks, roots, or tools around your feet.
Mixed use is common. ARB’s guide says a one-spot/one-flood combo is the best-of-both-worlds setup for most drivers. A combo bar or a separate pair of spot and flood lights works if you do a bit of everything on weekends — though budget combo lenses are often criticized because the spot portion is so weak the light “feels like just a flood.” Pure spot bars are also hard to find; many budget “spot” bars are actually narrow floods.
Keep these trade-offs in mind:
- Spot patterns: Intense and focused — great for distance but leave you with very little peripheral awareness.
- Flood patterns: Great coverage but won’t throw light very far.
- The Physics: At the same wattage, a wider beam always throws light a shorter distance than a narrow one.
- Budget reality: A $50–$80 combo bar handles about 90% of casual weekend scenarios.

How to choose
Deciding on a light bar starts with understanding beam angle. This is the formal measure of how wide the light spreads. A narrow beam angle means you have a spot-type beam, while a wide angle means you have a flood-type beam.
Think of it like water from a hose. A narrow, high-pressure stream hits a target far away, while a wide spray covers the whole garden but doesn’t travel nearly as far. If you spread the same amount of total light over a larger area, each square meter gets less light. This is why floodlights feel “dimmer” at a distance compared to spots.
When looking at combo bars, check if they use true distinct optics. A high-quality combo might have a 30° spot beam in the center and a 170° flood beam on the sides. However, many budget units use a “narrow-flood” that lacks a real concentrated center. If you absolutely need to see a mile down a desert road, don’t rely on a generic combo; look for dedicated spot patterns or high-quality pencil beams.
Product options
Depending on your budget and how much light you need, there are several ways to go.
Budget Options ($50–$80) These are great for recreational off-roading. A $50–$80 combo bar can handle about 90% of casual weekend scenarios.
Mid-Range ($150–$600) Smaller bars typically sit in the $150–$350 range. Higher-output bars can reach $375–$600. Typical setups across brands fall between $300 and $1,500.
Premium ($300–$1,500) For professional-grade setups, you can expect to pay significantly more.
- The KC HiLites Gravity Pro6 is a top-tier choice for performance and durability.
- The Rough Country Black Series offers great value.
- The Baja Designs OnX6 Arc is a high-end option around $1,300, available in various sizes and patterns.
Compatibility checks
Don’t let a bad wiring job ruin your new lights. If you install a large bar incorrectly, you can melt your switches or even your wires.
- Use a relay: A large 52” dual-row bar can draw about 40A. Most standard switches can’t handle that much power alone. A relay acts as a heavy-duty middleman to protect your switch.
- Match your connectors: Check your wattage. If your single-color bar is under 180W, you need a DT harness. If it is over 180W, you need an ATP harness.
- Wire gauge: Always use at least 14 AWG power and load wire.
- Fuse placement: Install your fuse close to the battery. Most guides suggest within 12 to 18 inches. Always check your specific harness manual first.
- Fuse sizing: Size your fuse slightly above the bar’s maximum draw. For example, if a 120W bar at 12V draws 10A, use a 15A fuse. If the fuse is too high, it won’t protect your circuit during a surge.
Setup & use notes
The way you aim your lights is just as important as the lights themselves. The biggest complaint from owners is glare. If your beam pattern is wrong or the light is aimed poorly, the glare and shadows can actually be worse than driving in the dark.
Remember that the beam pattern is created by the optics (the lens and reflector) in front of the LED, not the LED itself. Some premium brands, like Baja Designs, even allow you to swap lenses easily using O-ring seals so you can change from a spot to a combo pattern later.

Avoid-if guidance
Before you hit “buy,” make sure you aren’t falling into these common traps:
- Avoid cheap combos if you need distance: If your main goal is seeing far down a trail, many budget combo bars will disappoint you because their “spot” is essentially just a narrow flood.
- Don’t trust “spot” labels blindly: On bargain brands, many “spot” lights are actually just narrow-flood beams.
- Don’t assume size equals distance: A massive light bar doesn’t automatically mean it throws light further. Many large bars are designed for massive width (flood), not distance (spot).
- Avoid “bargain” expectations: You often get what you pay for. Cheap bars are more prone to flickering or fading.
FAQ
Can I swap lenses later? Yes, on many premium bars. Some brands use O-ring seals for easy changes, while others sell interchangeable Spot, Drive, or Combo lenses.
What is a driving/combo pattern? It is a mix of optics. For instance, a light might have a 30° spot beam in the center flanked by 170° flood beams on the sides.
Do I need a relay for a 20” bar? You should check the amp draw. If the bar pulls more current than your switch is rated for, you must use a relay to prevent melting the switch or wires.
How do I size the fuse? Pick a fuse rated slightly higher than the bar’s maximum current draw. A 120W bar at 12V draws 10A, so a 15A fuse is the correct choice.
