What's the difference between spot and flood beam patterns?

Spot beams project light far ahead (narrow angle, 5-15°) — ideal for high-speed off-roading. Flood beams spread wide (60-120°) — ideal for close-range work and slow trails. Combo beams offer both.

How many lumens do I need?

For auxiliary lighting, 3,000-6,000 lumens is adequate. For primary off-road lighting, 8,000-15,000+ lumens. More lumens isn't always better — beam pattern and optics matter as much as raw output.

What IP rating should I look for?

IP67 (dust-tight, 30 min submersion at 1m) is minimum for off-road use. IP68 (continuous submersion) is better for water crossings. IP69K withstands high-pressure washdowns.

Are cheap LED light bars worth it?

Budget bars work for occasional use but may have issues with water intrusion, flickering, or premature failure. Quality bars (Rigid, Baja Designs, Auxbeam) cost more but last years longer with better optics.

Do I need a wiring use and relay?

Yes. A proper wiring use with relay, fuse, and switch protects your electrical system. Direct wiring can overload circuits, cause fires, or damage the LED driver. Most quality kits include a use.

What size light bar fits my truck?

Measure your mounting location (grille guard, roof rack, bumper). Common sizes: 20" for grille mounting, 30-40" for roof/bumper, 50"+ for roof racks. Ensure clearance for hood operation.
