LED strips can become dimmer when supply voltage is reduced, but this is rarely the best control method. Most flexible strips are designed for fixed 12V or 24V DC input. Lower voltage may reduce brightness, but it can also cause uneven output, color shift, flicker, and weak performance along long runs.
For stable results, a PWM dimmer is normally installed between the constant-voltage power supply and the strip. PWM adjusts brightness by switching output rapidly while keeping the rated voltage. This provides smoother control and more consistent color than reducing supply voltage.
IEC 61347-2-13:2024 specifies safety requirements for electronic LED controlgear used on DC supplies up to 1,500V and AC supplies up to 1,000V. The IEC 62386 series covers digital control of electronic lighting equipment.
A direct LED strip manufacturer can match PCB design, LED density, resistance, voltage, wattage, controller, and power supply. A trader may depend on separate suppliers, increasing compatibility and batch-consistency risks.
Founded in 2006, we integrate design, R&D, production, and sales. Our OEM and ODM process covers requirement review, circuit selection, prototypes, dimming tests, sample approval, SMT production, aging, inspection, and packing.
Confirm rated voltage, wattage per metre, strip length, voltage drop, PWM frequency, controller load, driver capacity, IP rating, and wiring. Quality checkpoints should cover dimming smoothness, flicker, temperature rise, soldering, insulation, waterproof sealing, and aging. Export projects should also verify CE, RoHS, labeling, plug standards, and destination-market electrical requirements.
