Mini Pecan Pie Muffins. Iâm sharing another tried-and-true recipe from my cookbook. I love these mini muffins because theyâre delicious, easy to make (you donât even need a mixer), they freeze well, and theyâre done in 20 minutes! I brought these to school today to share in the teacherâs lunch room and they disappeared.
Example: Calculate Streetlight Watt of following Street Light Area, 1  Required Illumination Level for Street Light (L) is 6 Lux per Square Meter. 2  Luminous efficacy (En) is 20 Lumen per Watt. 3  Required Street Light Area to be illuminated (A) is 1 Square Meter.
So how do you determine which light fixture is going to be the best replacement if you canât just swap them out, watt for watt, like the old days? The actual measurement of how much light a lamp emits is referred to as âlumens.â However, the total lumens produced by a fixture, or âlight source lumens,â is not always equivalent to the number of lumens that are actually delivered. One way to measure the amount of light thrown from a fixture is by âfootcandlesâ (fc). When choosing an LED light, two of the most important data points to consider are lumens and footcandles. You can see a guide of recommended footcandles here.
