LED strips are popular for home, commercial, and outdoor lighting, but picking the right voltage—12V, 24V, or 48V—can be tricky. This guide explains why 48V LED strips are often the best choice, comparing them to 12V and 24V options. With 48V, you get better performance for bigger projects. It also makes installation easier and costs lower. Plus, it improves safety when you use the right accessories. Let’s look at the main differences, benefits, safety, and parts needed to find the best LED strip for you.
Why LED Strip Voltage Matters
LED strip voltage (12V, 24V, or 48V) affects brightness, wiring, and installation costs.
12V: This option is cheap and safe for small projects, like under-cabinet lighting. However, it is limited to 5–10 meters because the brightness fades.
24V: Better for medium projects like office lighting, supporting 10–20m runs.
48V: Less brightness loss, best for long runs, ideal for big projects like commercial or outdoor lighting, with less wiring needed.
Higher Voltage Means Less Brightness Loss
Brightness fades (voltage drop) when electricity travels through wires due to resistance. Higher voltage reduces current, cutting energy loss. For example, a 100W 48V strip uses about 2A, compared to 8A for 12V. Over 50m, a 48V strip loses just 5-10% brightness, while 12V loses over 50%. This makes 48V great for long runs without extra power supplies.
Choosing the right voltage simplifies setup and reduces costs. In 2025, 48V LED strips are trending for their efficiency and safety in large-scale lighting.

Why Choose 48V LED Strips? Comparing with 12V and 24V
48V LED strips stand out for long runs, simpler installation, and safety. Here’s how they compare to 12V and 24V.
Brightness and Performance
48V: Steady brightness over 50m+, perfect for large projects like store displays.
12V: Fades after 5–10m, needing extra power points.
24V: Fades after 10–20m, less ideal for big setups.

Installation
48V: Fewer wires and power supplies make setup easier and cheaper.
12V/24V: Complex wiring and more power points increase effort.
Safety and Durability
48V: Less heat from low current; waterproof (IP65/IP68) options suit indoor/outdoor use.
12V/24V: More heat increases risk; less durable outdoors without protection.
Cost
48V: Lower initial cost since it requires fewer power supplies, connectors, and wires, even though strip prices are similar. Long-term maintenance is also reduced.
12V/24V: Higher initial cost due to more power supplies and wiring; higher maintenance costs over time.

Are 48V LED Strips Safe?
Yes, 48V LED strips are safe when installed correctly with certified components. Running on 48V direct current (DC), they carry a lower risk of electric shock than AC systems, as DC is safer for human contact. The low current in 48V strips reduces heat, minimizing fire hazards and extending lifespan. Many include safety features like overcurrent and short-circuit protection. For outdoor use, IP65/IP68 waterproof models protect against moisture. Always use a matching 48V power supply and follow manufacturer instructions to ensure safety.
What Specific Accessories Are Needed for 48V LED Strips?
To set up 48V LED strips, you’ll need these key accessories:
Power Supply: Choose a DC 48V power supply matching the strip’s wattage (e.g., 500W for 50m at 10W/m, plus 20% extra for safety).
Controller/Dimmer: Select a DC 48V-compatible model to adjust brightness or color (e.g., for RGB strips).
Connectors: Onlumi offers solderless 48V LED strip connector ensuring secure and easy connections.
Wiring: Standard low-resistance wires (e.g., 16AWG) work fine, with no need for changes.
Mounting Clips/Channels: Use clips or aluminum channels for secure installation and heat dissipation.
Always choose certified accessories to ensure compatibility and safety with your 48V LED strip. Onlumi’s 48V LED strip connectors have been CE certified.
Where 48V LED Strips Shine
48V LED strips excel in various settings:
Home Lighting: Bright, even light for kitchens, living rooms, or patios.
Commercial Lighting: Ideal for stores or offices with no brightness fade over long runs.
Outdoor Projects: Waterproof strips for building exteriors or gardens, built to last.
Tips for Choosing 48V LED Strips
To pick the right 48V LED strip:
Brightness/Color: Choose warm (3000K) for cozy spaces or cool (6000K) for tasks.
Waterproofing: IP20 for indoors, IP65/IP68 for outdoors.
Quality: Pick certified brands for safety and up to 50,000 hours of life.
Conclusion
48V LED strips outperform 12V and 24V with less brightness loss, simpler setup, lower costs, enhanced safety, and durability. With accessories like Onlumi’s 48V connectors, they’re perfect for home, commercial, or outdoor lighting. Choose 48V for reliable, cost-effective results.
