Metal waterproof lamp is dangerous sites for combustible gas and dust, can prevent the lamp inside may produce arc, spark and high temperature ignites the combustible gas and dust in the surrounding environment, to meet the requirements of explosion-proof lamps and lanterns. Also known as metal waterproof explosion - proof lamps, explosion - proof lamps. Different combustible gas mixture environments have different requirements for the explosion - proof grade and explosion - proof form of metal waterproof explosion-proof lamps.

JY37 series waterproof fluorescence working lamp is used for the production, inspection, maintenance and display of all kinds of mechanical processing centers to meet the safety lighting conditions in humid acid, alkali and dust environment.

JL50D series halogen lamp is an inflatable incandescent lamp filled with partially halogen elements or halogens. In ordinary incandescent lamp, the high temperature of filament causes the evaporation of tungsten, and the evaporation of tungsten precipitates on the glass shell, resulting in the phenomenon of the bulb glass shell blackening. In 1959, JL50D series halogen tungsten foam working lamp was invented, which eliminated the black phenomenon by using the principle of halogen tungsten circulation.

JL50C series halogen lamp is an inflatable incandescent lamp filled with partially halogen elements or halogens. In ordinary incandescent lamp, the high temperature of filament causes the evaporation of tungsten, and the evaporation of tungsten precipitates on the glass shell, resulting in the phenomenon of the bulb glass shell blackening. In 1959, JL50C series halogen tungsten foam working lamp was invented, which eliminated the black phenomenon by using the principle of halogen tungsten circulation.

JL50B series halogen lamp is an inflatable incandescent lamp filled with partially halogen elements or halogens. In ordinary incandescent lamp, the high temperature of filament causes the evaporation of tungsten, and the evaporation of tungsten precipitates on the glass shell, resulting in the phenomenon of the bulb glass shell blackening. In 1959, JL50B series halogen tungsten foam working lamp was invented, which eliminated the black phenomenon by using the principle of halogen tungsten circulation.

L40A series halogen lamp is an inflatable incandescent lamp filled with partially halogen elements or halogens. In ordinary incandescent lamp, the high temperature of filament causes the evaporation of tungsten, and the evaporation of tungsten precipitates on the glass shell, resulting in the phenomenon of the bulb glass shell blackening. In 1959, JL40A series halogen tungsten foam working lamp was invented, which eliminated the blackening by using halogen tungsten circulation principle.
