The Emergency Airfield Lighting System

The PAPI unit locations must be verified using a surveying instrument
It is dependant on your make and model. You can either upgrade the entire headlight unit, or replace the bulb and add a ballast unit. In either case, you must ensure the headlight beam pattern is correct.

i want to buy a beam pumping unit, what the data should be in the requested form?
The power of a laser beam is typically measured in watts (W). This measurement indicates how much energy the laser beam is emitting per unit of time.
It is a unit of time and distance. A light year is the amount of time it takes for a beam of light to travel through space in one earth year, which is 5.9 trillion kilometers. Time : one year, distance : 5.9 trillion km.
The distance a beam of light travels in one year in a vacuum is called a "light year". It is equivalent to just under 9.5 trillion kilometres.
The unit used with the triple beam balance is usually grams (g) for measuring mass.
The intensity of a laser beam refers to the amount of power per unit area that the beam carries. It is a measure of how concentrated the energy is in the beam.
13000 MCD (millicandela) is a unit of luminous intensity, not luminous flux like lumens. The relationship between lux and lumens depends on the beam angle of the light source. You would need to know the specific beam angle of the light to convert MCD to lumens.
Optical power is the degree to which the lens will converge or diverge light. The unit of measurement is the diopter and is directly related to how much a beam of light is bent by the lens.
