Quick answer: below are the LED lighting terms you'll run into when choosing lights — lumens, lux, candela, color temperature, IP rating, SAE/DOT/ECE and more — each explained in plain language by the SC LED team. Lumens The total amount of light a source emits. More lumens does not always mean more usable light — beam pattern and optics decide how much actually reaches your target. Lux Light intensity landing on a surface (lumens per square meter). It tells you how bright th

Quick answer: first define what you want them for (high speed, work, fog, daily use), then pick the matching beam pattern, then the size/power for your mounting space, and finally confirm whether they need to be street legal. Step 1: define your use Fast in open terrain? You need reach (spot/driving). Work or camping? Width (flood). Fog or dust? Fog. Mixed use? Combo. Step 2: choose the beam pattern With your use clear, the pattern almost picks itself. For a single versatile

Quick answer: each pattern does something different. Spot concentrates light far away; Driving balances reach and width; Flood lights up wide and close; Fog throws a low, wide beam that cuts through fog and dust; Combo blends spot + flood. Your choice depends on speed and terrain. What is a beam pattern and why does it matter? The pattern is how the light is projected. Two pods with the same lumens can perform very differently: one lights far but narrow, another floods a wide

Quick answer: the SC2 is the most compact (tight spaces); the SC3 / SC3 Pro is the balanced, most popular choice (general use); the SC5 prioritizes long distance; and the SC7 Pro is the flagship for maximum performance. If unsure, the SC3 Pro is the safe pick. How to choose between the SC series Simple rule: bigger size means more reach and output, but also more mounting space and price. Choose by your use and available space. Comparison table: SC LED pods Model Diameter Best

Quick answer: it depends on the light and where you use it. Street-legal lights meet standards (a DOT mark and SAE J581 for driving lamps or SAE J583 for fog lamps), have a beam cutoff to avoid blinding traffic, and emit only white or amber. Off-road lights are not approved for the road. Note: rules vary by country and state/region. Always check your local regulations. What makes a light street legal? It must carry a DOT mark (meets US FMVSS 108), meet SAE J581 (driving) or J

Quick answer: TIR stands for Total Internal Reflection. It's a lens that wraps each LED and directs almost all its light forward with precision, instead of bouncing it off a reflector. The result: more distance, a cleaner beam, and less wasted light than traditional reflector optics. How does TIR optics work? Each LED sits inside a precision lens (optical-grade polycarbonate) that captures light leaving the diode in all directions and, through total internal reflection, strai

Quick answer: for most drivers today, LED is the best choice - more usable light per watt, about 10x longer life than halogen, and instant on. HID (xenon) is bright but fragile and slow to warm up; halogen is cheap but inefficient and short-lived. At SC LED we've spent 12+ years installing automotive lighting, and this is the question we hear most. What's the difference between LED, HID and halogen? Halogen heats a filament (lots of heat, little light). HID creates an electri
