Usually, no. Having a screen capable of a brighter screen is important, but you’ll only need that max brightness if you’re outdoors in bright sun or under ultra-bright fluorescent lights. Opting for a slightly lower nit number to save money is perfectly okay. Why does some content seem ...
provides a brightness equalizing light filter system which can be utilized as the bottom panel or as one of a set of bottom panels in an indirect fluorescent light fixture to evenly illuminate the fixture to approximately the same degree of brightness as the surrounding area which it lights. The...
What happens to a bulb when a conductor is wired in series with the bulb (bulb lights or doesn't light)? Is the switch open or closed? What happens when a light bulb burns out? In fluorescent lamp when voltage increases current also increases. Explain why. The ...
