WHaT IS THE CONCEPT OF INDUCTION LAMPS IN MODERN LIGHTINGS, and HOW IT WORKS TO EMIT LIGHT ( AS NO ELECTRODES ARE PRESENT ) ?" COULD INDUCTION LAMPS CAUSE INTERFERENCE WITH COMUNICATIONS INTO A STORE USING INDUCTION LIGHTING ? WHAT IS THE BENEFIT OF USING THE LOW FREQENCY INDUCTION LAMP , VERSUS LED , AND VERSUS FLUORESCENT, AND VERSUS ANOTHER KIND OF LIGHTING . THANK yOU MOISES GUINDI

Lux meter is the measuring device to measure the lux level of lighting fixture. in industrial sector two types of lighting fixture is being used as street lighting purpose 1. HPSV (Sodium) and 2. HPMV (Mercury). HPMV having white light which is an combination of red, blue and yellow colour, while HPSV haivng Yellow lighting. in HPSV red & blue colour will be absent. during measurement of the lux level of HPSV and HPMV fixture. 1. Lux meter can measure the actual lux level of both fixture? 2. or it will show false reading for HPSV fixture light as it has only yellow light present. please give me answer
