A 1.8W LED module refers to an LED lighting module with a total power consumption of 1.8 watts. This number represents the power consumed by the LED module under normal operating conditions. LED modules are typically used for lighting applications, as they have high efficiency and long lifespan, giving them significant advantages in energy conservation and environmental protection.

1.8 watt LED modules typically provide illumination with a certain level of brightness, but the specific brightness level will depend on factors such as LED design, size, and efficiency. You can choose the appropriate LED module based on your specific lighting needs to ensure that it meets your lighting requirements.

Please note that the brightness of LED modules is usually measured in lumens, so when selecting an LED module, you may also need to consider its lumen output to ensure that it meets lighting requirements
