405nm is widely using in disinfection, bacterial disease cure,or microbial infection prevention etc. It does no harm to human. But it's blue not friendly for eye view.

Feton LED chip model COB SW1919-40W-40FR90 emits this disinfection blue light as white. Lighting while disinfection: Lowing risk of infection happens in the public environment

Smart Control of COB SW1919-40W-40FR90
To control a 40 watt COB LED, you will need a driver that can handle the power requirements of the LED.

Once you have a suitable driver, you can use a smart control system to control the LED's brightness and other parameters. Here are some options for smart control:

PWM Dimmer: A pulse-width modulation (PWM) dimmer can be used to adjust the brightness of the LED by adjusting the duty cycle of the PWM signal. PWM dimmers are available in a variety of formats, including standalone units and integrated circuits (ICs).

Digital Potentiometer: A digital potentiometer can be used to adjust the LED's brightness by varying the resistance of the potentiometer. This is a simple and cost-effective solution that does not require any complex programming.

Microcontroller: A microcontroller can be used to control the LED's brightness and other parameters, such as color and effects. This solution requires programming knowledge and the use of suitable development tools and hardware.

Smart Lighting Systems: Smart lighting systems can be used to control the LED's brightness and other parameters through a smartphone app or voice commands. These systems often use a hub or gateway device to communicate with the LED driver and other smart devices in the home. Examples of smart lighting systems include Philips Hue, LIFX, and Wiz.

Ultimately, the choice of smart control solution will depend on the specific requirements of your application and your level of expertise in programming and electronics.

There are many led grow lights manufacturers, but we are one of the best choices for you.
