THT-EX Explosion-proof LED lights were installed on Ocean researcher No. 3 of the Institute of Undersea Technology of Kaohsiung Sun Yat-sen University. After a long period of installation and operation under a humid and salty environment, the lights are still in good condition. Our 100W and 120W UL, IECEx, ATEX and ABS approved explosion-proof LED lights were utilized here. THT-EX is committed to provide all kinds of high-quality products to meet the needs of different harsh environments.
