Jan 28, 2024 · According to industry standards, LED lights produce about 80-100 lumens per watt, while traditional incandescent bulbs might produce about 10-17 lumens per watt. This means
Utilizing the 7:1 ratio, you can estimate the wattage by dividing 100 watts by 7, resulting in roughly 14 watts for the LED bulb. However, note that the luminous efficacy may differ among manufacturers, so the most reliable approach is to refer to the Lighting Facts label and aim to match the lumens of the LED bulb to ensure the desired brightness.
Most solar lighting systems use fixtures ranging from 20 Watt LED (2000+ Lumens) to 90 Watt LED (9000+ Lumens) and are typically in the 35 Watt to 50 Watt range for most applications. High security or light level requirements use the brighter lights and residential and remote areas use the lower range.
Using the 7:1 ratio, simply divide 60 watts by 7 to get roughly 9 watts. But efficacy varies greatly from manufacturer to manufacturer, so it’s best to check the Lighting Facts label and try to match lumens. Also, a label will sometimes (but not always) tell you that an LED bulb has an equivalent brightness.
A much lower wattage LED can be used. The ASL fixture provides replacements for 150 Watt, 250 Watt and 400 Watt HPS and MH lights using fixtures with a Wattage of 62 Watts, 123 Watts and 181 Watts. In the end, taking into consideration the lighting levels and Lumens over the Wattage of the lamp will provide a more energy efficient lighting system.
The higher the wattage, the brighter the light, but also the more power it uses. The efficiency of this system was introduced using incandescent lamps. For instance: 40 Watt incandescent lamp produces only 380-460 lumens and uses 40 Watts of energy per hour.
A 60-watt bulb consumes 60 watts of energy. Since we used 60-watt incandescent bulbs for so many years, we associated a certain level of brightness with 60 watts. But we can’t do that anymore, since LED technology produces more light while using fewer watts. Instead, we need to use lumens. A lumen is a measure of visible light energy.
