For those looking for high-temperature LED lighting, heat-resistant 135°C high ceiling lighting "HD Series".

Due to frequent outages of ceiling lighting in factories and warehouses caused by extreme heat, we have released the HDR series of countermeasure products!

There are abnormalities occurring with factory and warehouse lighting. Due to the extreme heat caused by global warming, temperatures near the ceiling have risen above 60°C, leading to frequent failures of conventional LED lighting. There is an urgent need to switch to high-temperature resistant LED lighting! The HDR series is a high-temperature LED high-bay lighting solution that can be used in environments up to 60°C. It is the ideal product for replacing lighting that has failed due to high temperatures!

[To the owners of parking lots and parking lot construction companies] "I'm worried about the possibility of colliding with pedestrians when exiting the parking lot..." Among vehicle entrances to parking lots, stores, residences, and factories, those facing sidewalks or roadways are particularly prone to dangerous incidents such as collisions with pedestrians or between vehicles. To alleviate such concerns, Hotron proposes a [Vehicle Exit Warning Sensor] that detects vehicle departures at various sites and alerts the surroundings with LED lights and buzzers. The system consists of a simple configuration of "Sensor" + "Controller" + "Switching Power Supply (24V)" + "LED Rotating Light." *When using the exit warning system, we kindly ask customers to arrange for the switching power supply (24V), LED rotating light, control panel, circuit breaker, etc. Since it can be retrofitted, it can also be used for existing parking lot entrances. [Contents Included] ○ Vehicle Exit Warning System Configuration ○ Comparison Table of Exit Warning Sensors ○ Four Modes ○ Wide Range of Applications ○ Customer Feedback ○ Appearance Diagram / Specifications ◎ For more details, please contact us or download the catalog.
