Newsletter Sign-Up . So, what is the use of a measurement like foot-candles? You already know about how to convert foot-candles to lumens (Lux) and Watts: A To calculate Lumens (Lux) from foot-candles: Lumens = Foot Candles x 10.76, B To calculate Watts from foot-candles: Watts = Lumens x 0.001496, C You can also calculate the number of watts directly from foot-candles by combining both equations & using the following: Watts = Foot Candles x 0.01609696.
5mol / day -acceptable for some plants, 10mol / day -for a plant enough dose, 20 + mol / day - Ideal dose for the vast majority of plants, VERTICANA® - for houseplants & green walls, I want to make a complaint about the product. The luminous flux Φ V in lumens (lm) is equal to the power P in watts (W), times the luminous efficacy η in lumens per watt (lm/W): Here is a simple illustration that will help you understand the foot-candle measurement.

document.onreadystatechange = function(){ For the case of this example, we will base our calculations on a measurement of 50 foot-candles. You will then be given the number of lumens needed and the equivalent of this in light bulbs. "500, 400, 700" means a panel with diodes 500,400,700 of equal power. Congratulations! Lux to Lumens Calculator The lux to lumens calculator below will help you choose the illumination solution that best meets the specific requirements of your application. The explanation for this choice dates back to the origins of the candle itself. Please note that one foot-candle = 10.76 Lumens*, which means that in order to convert foot-candles to lumens, I would need to take the amount of foot-candles that I measured, 50 foot-candles ,and multiply by 10.76 to get the number of lumens (50 x 10.76 = 538 lumens). A more scientific definition exists today, but this drawing helps visualize the lumen. Any business or organization that has physical security requirements also need to be aware of the foot-candle readings in sensitive areas, and around cameras and doors.
