Rang Dong Smart Farm and Agricultural LED Lighting

Rang Dong is a Hanoi-based Vietnamese manufacturer of lighting and electrical products that supplies an LED 4.0 ecosystem, including specialised lighting and IoT solutions for high-tech agriculture. Its agricultural line addresses high electricity costs and inefficient traditional lamps used for flower induction in dragon fruit, chrysanthemum and tissue culture.

The Rang Dong Smart Farm solution combines a central controller, sensors for light, temperature, humidity, CO2 and soil moisture, phone-based remote control and specialised LED lamps. It controls light spectrum, intensity, timing and duration for each growth stage, enabling off-season flowering and remote adjustment of greenhouse conditions. Dragon fruit lamps use a three-peak spectrum at 450, 630 and 730 nm. The system is deployed with farms, cooperatives and households in Hai Duong, Vinh Phuc, Da Lat, Hoa Binh and Binh Thuan.

• Central controller: manages lighting schedules and greenhouse equipment from one unit.
• Environmental sensors: measure light, temperature, humidity, CO2 and soil moisture.
• Remote control: growers adjust greenhouse conditions from a phone.
• Spectrum control: tunes light spectrum, intensity, timing and duration by growth stage.
• Dragon fruit LED: three-peak 450/630/730 nm lamps for off-season flower induction.
• Specialised lamps: dedicated LED lines for chrysanthemum, vegetables and tissue culture labs.

• Dragon fruit cooperatives in Binh Thuan and Long An replacing compact lamps with LEDs for off-season flowering.
• Chrysanthemum growers in Da Lat automating night lighting schedules and greenhouse climate.
• Plant tissue culture laboratories and seedling companies cutting lighting and cooling costs.

• Dragon fruit lighting power drops from 9 W to 5 W, saving up to 45% versus 9 W LEDs and 75% versus 20 W compact lamps, according to the company.
• Chrysanthemum lamps run at 5 W with lighting cut to 4 hours per night.
• Tissue culture LEDs use over 60% less energy than fluorescent tubes and reduce cooling costs.
• A melon farm reported about 15% higher sweetness and 10-15% heavier fruit.

Vietnam's high-tech agriculture programs promote greenhouses, off-season production and energy saving, while dragon fruit and flower growers face rising electricity costs from traditional lamps. Demand is growing for domestically made LED lighting combined with IoT sensors and remote control that smallholders and cooperatives can afford.

Vietnamese lighting manufacturer headquartered in Hanoi; business registration certificate issued on 15 July 2004. Its LED technical process for dragon fruit flower induction (LED.TL-T60 WFR/9W) was recognised as a technical advance by Vietnam's Department of Crop Production. Also offers rooftop solar and smart lighting solutions.
