Having problems with lights lasting around coal stock piles and handling areas? We have designed these lights for coal stock piles and handing plants. High sulfur from coal is the cause of lights failing as it is very corrosive and damaging to electronics. Our lights are made of high grade steels and are coated in a special coating to eliminate this. These lights will not turn yellow. We have a huge range of power and light options for every situation.

One of these lights can replace two older metal halide lights. Stainless and alloy construction so no more lights breaking off and falling due to rust.no more down time replacing bulbs. Low current draw.

There are various harmful substances capable of causing corrosion or damage to the electronics in general or the LED specifically. Because high concentrations of sulfur compounds can be a reason for defective LEDs. It is known that H2S can evaporate especially from Coal materials. when used near LEDs. As an example a silicone cast LED and the effect of hydrogen sulfide Without coming into contact with the harmful gas, the lead frame of the LED has a shiny surface. But after contact with a system containing H2S the surface turns brown or black, noticeable by visual inspection (for LEDs with a clear casting). The presence of a micro climate, containing sulfur compounds, causes a chemical reaction of the diffused gases with the silver lead frame plating. The silver layer transforms into silver sulfide. In this particular case the corrosion leads to an open contact, as the bond wire is disconnected. This happens because silver sulfide is not electro-conductive and its volume is greater than the volume of silver. This then leads to a mechanical separation between the bond wire and the connecting lead. In other cases it can lead to an open contact because of lifted glue or other functional failures.Corrosive gases can penetrate through the encapsulation of the LED, especially when a silicone encapsulation is used.This can lead to corrosion of the different metals used in the LED. If gases diffuse through the encapsulation, the lead frame may become discolored. This corrosion can affect the performance and the lifetime of the LED negatively and lead to a failure.
