You can calculate watts from lumens and luminous efficacy. Lumen and watt units represent different quantities, so you can't convert lumens to watts.Lumens to watts calculation formulaThe power P in watts (W) is equal to the luminous flux ΦV in lumens (lm), divided by the luminous ...
You canupgrade from fluorescents to LEDsin two distinct ways. Firstly, you can do a lighting retrofit to your existing fixtures to make them function for LED lighting. This is known as retrofitting. Secondly, it is possible to replace the lighting fixtures entirely withmodern LED lighting. Once...
Wattage is no longer the best way to determine which bulb will be a direct replacement for the bulb that just burned out. LED bulbs use a lot fewer watts than incandescents to produce the same level of light. Instead of watts, look for the number of lumens, the measure of how much li...
But bear in mind, I’m trying to design a bespoke studio where I’ll be painting 12 hours a day some days, through gloomy British weather and many a midnight painting session. So I need a space that has both natural light and the best quality artificial light. There are so many variab...
