LaoA high pressure sodium bulb works by creating light through the process of electrical current passing through a mixture of gases and a sodium vapor inside the bulb. When the current passes through the sodium vapor, it produces a glowing plasma that generates the characteristic yellow-orange light emitted by high pressure sodium bulbs.
Pretty much the same way as any gas or metal film lamp works. The voltage from a ballast(balances current and increases voltage to the bulb) heats up a metal filament which in turn, when the temperature is hot enough, causes the sodium to ignite. The filament keep the sodium burning.

Can you use a 70 watt high pressure sodium bulb in a 100 watt ballast?
No. The bulb has to match the ballast wattage exactly. And you can't interchange different lamps (like metal halide) either. The ballast is specific to that wattage and lamp type. The bulb will either burn out quickly or just not work properly at all
Can you use a hps bulb in a metal halide fixture?
In most cases a cfl bulb can be replaced with an incandescent bulb as long as the base matches. for an example: if a cfl bulb has a GU24 base an incandescent bulb will not work! Also, ensure the wattage of the bulb does not exceed manufacturers rating.
Formula to work out humidity?
Relative humidity can be calculated using the formula: Relative Humidity = (Actual Vapor Pressure / Saturation Vapor Pressure) x 100 Where: Actual Vapor Pressure is the pressure exerted by water vapor in the air, and Saturation Vapor Pressure is the maximum pressure possible at a given temperature.
How does low pressure and high pressure work in meteorology?
In the atmosphere we have air pressure. Low Pressure systems allow for cloud formation, the lower the pressure the more intense a storm can be. So you would get storms around Low Pressure systems. This does not mean that as soon as the pressure in the atmosphere drops cloud start forming immediately, that takes time.On the other hand we have High Pressure Systems, in high pressure systems do not allow for cloud formation, thus, you would have sunny weather around these systems.
Why you prefer to connect tubes to low pressure connection at car air conditioning system compare to high pressure connection in air cond?
It is called high pressure for a good reason. The high pressure side can and will pump the refrigerant back into the can of refrigerant and explode in your hands. One more reason to let the professionals work on the air conditioning in your vehicle.
