Pitfalls of luminometer


Is it mistake to choose the one that suits you from measuring the brightness of the luminometer ?


Make no mistake that LED lighting has a different brightness from the fluorescent lamps that are currently installed. Lighting and brightness will continue to fall gradually over lighting time. If the already installed lighting has passed 3-4 years maintaining the same brightness, the new illumination falling of brightness then will no longer be maintained. The current fluorescent lamps when purchased were much brighter. In the case of LED lighting, irradiation range there is often narrower than the fluorescent lamp, and it is better that you make the illuminance measured at several points just below the lighting. In addition, during the measurement, you must have the consideration of such conduct after confirming whether it is or not the incoming external light using same measurement instrument.
