One way to compare lamps is by looking at how much energy they need (measured in watts) to produce the same amount of brightness (measured in lumens). Dividing these two numbers, we get the number of lumens each lamp can produce for a single watt of energy. Looking at the chart here,...
Using LED panels, the light is evenly disturbed and spread without dim spots. So, the lighting looks pleasing, even within the panel. They offer a bright option to replace a 2×4 lighting fixture with two tubes. To replace a 2×4 lighting fixture, this fixture employs 40 Watts and provid...
In the past, it was common to hear someone say a bulb is "so many watts (W)," with higher numbers indicating greater brightness. However, watts (W) represent the power of a standard bulb, and higher wattage consumes more electricity. Lumens are the unit of luminous flux, referring to t...
Again, balance is the key. If there’s some light still in the sky, rather than extending the exposure, you’ll need more power from the light source. Otherwise, the sky can be too bright. Exposure will give you more time to light, but it will also increase the exposure time on ...
