The DC 24V 20mm 12 LED Ultrasonic Mist Maker is a compact waterproof mist generator featuring a 20mm alloy ultrasonic plate for producing fine, dense mist. Its 12 waterproof LEDs create a colourful fog effect with three alternating colours, making it ideal for aquariums, fish tanks, fountains, gardens, home décor, and DIY projects. It operates using a 24V DC power supply with a minimum 1A output and includes a 5mm DC female jack with a 1-metre cable. For best performance, maintain 4–5cm of water above the module and avoid immersing it deeper than 5cm.
