250 watt mercury mercury vapor lamp Iran

Mercury vapor lamps are a type of gas lamp that has a higher luminous efficiency of about 65 lumens per watt than our incandescent or conventional incandescent lamps. In these lamps, light is produced by passing current through the steam of mercury. To make it easier to set up, these lamps add some argon gas to take the mercury out of the liquid state and turn it into gas.
These lamps are used in the lighting of passages and in the so-called turtle lights .

Direct or self-contained direct mercury vapor lamps or incandescent mercury lamps do not require a separate ballast (transformer) and a side start circuit.

This lamp with a power of 250 watts and a lifespan of 20,000 hours with 360 degree brightness is one of the types of mercury vapor lamps produced by Noor Lamp Company.
