This is a comparison of the MH system watts used as compared to the LED system watts. When considering the conversion of 500 lumens to watts, you need to consider the type of bulb or light source you are using. be added to maintain sufficient lumens for the task. Access Fixtures lighting engineers recommend that a MF of 20%. For example, if a tennis court design delivers 30 footcandles (fc) and 30fc is required for that level of tennis, there will not be enough light to play tennis at 25fc. Enough light when new may not or will not be enough light later. That means that over 100,000 hours of use the lumens emitted will decline to 70% of the original light emitted by the LED luminaire. Lux can only be measured by knowing the distance and the area the lumens have to travel to. Useful comparative measurements often asked: Lux. LED luminaires have an L70 rating such as L70 100,000 Hours. Lumen to watt comparison chart for LED, CFL, Halogen & Incandescent lamps 600 Lumen Conversions. Typically, the higher the wattage, the higher the lumens, and the more light output. A standard 40-watt (40W) bulb is equal to 400+ lumens. It refers to a light bulb's brightness, intensity of light and visible light emitted. , so there is a calculation required similar to HID Mean Lamp Lumens. A lumen measures the amount of light that comes from a bulb. LED luminaires have lumen depreciation too. equivalent wattage before adjusting for the Maintenance Factor. For example, the traditional 40-watt incandescent light bulb that produces 500 lumens has an efficacy of 12.5 (500 lumens 40 watts 12.5 lumens per watt). Sunlite 80544 LED G16.5 Globe Light Bulb, 7 Watts (60W Equivalent), 500 Lumens, Dimmable, Candelabra E12 Base, Short Bulbs, Vanity Bulbs, Energy Star Listed, Clear, 1 Count Visit the Sunlite Store 4.2 4. This is calculated by dividing the HID Mean Luminaire Lumens by the LED Luminaire Lumens per Watt.
