The National Test House (NTH) successfully conducted a unique customized test on the “LED Tower Mast Light”, specifically designed for challenging environmental conditions, such as sub-zero, high-altitude environments and extremely hot, dusty deserts.

The tests were conducted by the Lamp and Photometric laboratory of NTH (ER), Kolkata analysing the photometric, electrical, and ingress protection (IP) testing parameters on these samples, adhering to IS: 16106-2012, IS: 10322: Part-I -2014, and specific customer specifications. A significant component of the testing was the High-Altitude Test, which verified the functionality of the LED Tower Mast Light along with the Generator set, at altitudes over 1800 meters above sea level. This test was successfully executed in the Darjeeling district of West Bengal.
