What is the hansonled led module power consumption?

When designing signage, light boxes, or commercial displays, understanding LED module power consumption helps you choose the right driver, control energy costs, and ensure reliable operation. As a professional LED module manufacturer, HansonLed offers a wide range of modules with clearly rated wattages for different signage applications.

What Does LED Module Power Consumption Mean?

LED module power consumption is the amount of electrical power a module uses when operating, measured in watts (W). It is determined by three main factors:

• Forward voltage (Vf): the voltage required by each LED chip in the module.
• Drive current (I): the current flowing through the LED, usually measured in milliamperes (mA) or amperes (A).
• Number of LEDs (n): how many LED chips are connected in series or parallel inside the module.

The basic formula for estimating module power is:

For example, if a module contains three series-connected LEDs, each with a forward voltage of 3 V, and is driven at 0.24 A, its power consumption is approximately 2.16 W. This calculation gives you the base LED power. In real installations, you should also allow a small margin for the power supply efficiency and wiring losses, typically adding 10–20% to the total load.

HansonLed LED Module Power Ratings

HansonLed produces LED modules across multiple power levels to match different sign types and brightness requirements. Based on our product catalog, common power ratings include:

• 0.72 W modules: compact units such as the Ultrasonic LED Module 2LED and High Efficiency 2LED Module, suitable for small channel letters and slim signs.
• 1.2 W modules: including the Ultrasonic LED Module 3LED, ideal for medium-depth channel letters and general signage.
• 1.5 W modules: such as the High Efficiency 3 LED Module, offering brighter output for larger letter faces.
• 2 W modules: including the High Efficiency 4 LED Module, designed for bigger signs and deeper cabinets that need higher luminous flux.

These ratings are clearly listed in our product specifications, making it easy to calculate total project consumption by multiplying the module wattage by the number of modules used.

How Power Consumption Affects Your Project

Choosing the correct module power is not only about brightness. It also affects several practical aspects of your installation:

• Power supply sizing: add up the wattage of all modules and choose a driver rated for at least 120% of that total to ensure stable operation.
• Operating cost: lower-wattage high efficiency LED module products reduce electricity bills, especially for signs that run continuously.
• Heat management: higher-power modules generate more heat, so proper spacing and ventilation become important for long-term reliability.
• Regulatory compliance: accurate power data helps meet local electrical codes and certification requirements.

Matching Power to Signage Applications

Different signage jobs need different power levels. Here are typical recommendations based on HansonLed's product families:

Conclusion

LED module power consumption is a key specification for any signage project. By using the formula P = Vf × I × n and selecting modules with the right wattage, you can build efficient, long-lasting signs. HansonLed provides clearly rated modules from 0.72 W to 2 W across multiple series, helping installers and designers match brightness, efficiency, and power supply requirements for channel letters, light boxes, and outdoor displays.
