Lux to watts calculation with area in square feet The luminous fluxΦVin lumens (lm) is equal to 0.09290304 times the illuminanceEvin lux (lx) times the surface areaAin square feet (ft2): ΦV(lm)= 0.09290304×Ev(lx)×A(ft2) The power P in watts (W) is equal to the luminous fluxΦ...
A light meter can be used to measure candlepower. Insert the candlepower measurement into the following formula: L=C/0.07958, For example, 200 candlepower would equal: L = 200 candlepower / 0.07958. Do the division using a calculator: 200 candlepower / 0.07958 = 2 513 lumens. Related ...
When it comes to appearance, LED tubes look exactly like fluorescents. However, they are very different. First, LED is a mercury-free lighting solution. There is no costly recycling fees associated with LED lights. And you will never have to worry about a tube dropping and contaminating an ...
The luminous flux ΦV in lumens (lm) is equal to the power P in watts (W), times the luminous efficacy η in lumens per watt (lm/W):ΦV(lm) = P(W)×η(lm/W)Solumens = watts × (lumens per watt)orlm = W × (lm/W)...
