Many customers do not know how to choose the light source when purchasing explosion-proof lamps. Explosion proof lighting fixtures refer to those with explosion-proof shells and internal light sources that can be freely selected according to needs. For example, the BAD series explosion-proof lamps can be equipped with metal halide lamps, energy-saving lamps, and incandescent lamps. Below is an introduction on how to choose a light source.
1. According to the illuminance
High illumination standard: Generally speaking, high-intensity gas discharge is an extremely economical choice.
Exception: When the lighting fixtures must be placed within the normal visible range of the operator, low brightness light sources such as fluorescent lamps should be used.
Low illumination standard: All light sources can be considered.
Exception: High intensity discharge lamps are generally chosen for medium or high installation.
2. Feasibility of maintenance
High intensity gas discharge lamps should be used in environments that are difficult to maintain because the light source has a longer lifespan.
3. Working hours
It is more economical to use high-intensity gas discharge lamps and fluorescent lamps when working for over 2000 hours per year; Incandescent lamps are more economical when working less than 2000 hours per year.
4. Other factors
When the energy cost is high, high-intensity gas discharge lamps are usually economical.
Safe type: Emergency lights and places that require frequent switching are generally not selected due to the slow restart of high-intensity gas discharge lamps.
