LED High Bay Lights

HBK(Ultua) SERIES

The HBK Ultua Series LED High Bay Lights from SEEKINGLED is a different type of industrial LED high bay lights. It was originally developed for smelting and heavy industry sites where the temperature around the lamp is far beyond normal warehouse conditions. Many factories still rely on HID lamps mainly because most LED fixtures cannot survive continuous exposure at +60°C or beyond. This series solves that issue by allowing stable operation from -40°C all the way to +70°C.

At the same time, industries such as ceramics, glass production, thermal power generation, tire plants and metal workshops often run lighting for long hours without shutdown. In these areas, the ability of the driver to resist high temperature aging plays a major role in maintenance cost. SEEKINGLED uses an Inventronics constant-current driver without electrolytic capacitors, combined with protections against overheating and short-circuits. The design extends real lifetime rather than just showing a long laboratory number.

On the opposite side, low-temperature applications such as oilfield winter operations and semiconductor or cold-storage facilities also require strong reliability when the ambient temperature drops sharply. HBK Ultua heat resistant led lights uses Nichia 3030 LEDs with stable light output at low temperature, while IP66 protection and IK08 resistance cover dusty, humid or corrosive process environments (C3 category). The housing colour is Tiefschwarz (RAL9005), which visually matches modern industrial equipment and high-temperature plant aesthetics.

The heat-sink follows a chimney-effect structure with both upward and downward air movement, so the airflow is natural and does not rely on active cooling. With 140lm/W efficiency at 4000K Ra80, this configuration balances energy saving and tolerance to process temperatures, which is the actual problem faced in hot industrial environments rather than chasing theoretical maximum lm/W.
