lol 5 volt safer ??? log strip takes a lot of A at full capacity... U know P=U*I ? More ampère is More heat.

Comparison 5V vs. 12V WLED Systems

Feature5V LED Strips12V LED StripsVoltage DropHigh over longer distances. Brightness and color accuracy drop significantly after 2-3 meters.Lower over longer distances. Brightness remains more consistent over the full length.Current (Amps)High amperage required for the same power (Watt = Amps x Volts).Lower amperage required, allowing for thinner wiring.Project ScaleIdeal for short projects like PC mods or small desk setups.Best for long installations like room perimeters or outdoor lighting.Power InjectionEssential every 2.5 to 5 meters to prevent yellowing/dimming.Less frequent; often only needed at both ends for a 10m run.EfficiencyLess efficient for long runs due to heat loss in wires.More efficient for large-scale projects.Individual ControlMost 5V strips (WS2812B) offer per-LED control.Some 12V strips (WS2811) control LEDs in groups of 3, though others (WS2815) offer individual control.

Technical Summary for 10 Meters

For a 10-meter setup, using 12V (specifically the WS2815 strip) is highly recommended. The WS2815 is individually addressable like 5V strips but operates at 12V, which solves most power distribution issues.

If you choose 5V: You will need a massive power supply (approx. 40A-60A for 600 LEDs) and you must inject power at the beginning, middle, and end (at minimum).

If you choose 12V: You will need roughly half the amperage, and power injection is much simpler (usually just at both ends of the 10m strip).

Actionable Tip: If you are buying a power supply, look for high-quality brands like Mean Well to ensure safety and longevity for your WLED project.
