For example suppose you have a parking lot light that uses a 250-watt metal halide HID lamp.
Solar light lumens chart. Solar street light lumens varies depending on street lighting application. 100 lumens is equivalent to about 20 watts. A 40-watt fluorescent tube for example is rated around 2300 lumens.
Moreover these solar lights also have a built-in 36000 mAh battery. Simply take your current incandescent watts and select the corresponding LED bulb equivalent on the lumens brightness scale. For the average space of 250 square feet youll need roughly 5000 lumens as your primary light source 20 lumens x 250 square feet.
Bulb efficiency may vary. 50-300 lumens Path lights. T8 LED Tube.
For lumens the higher the lumens the brighter the light. LED technology typically produces 70-100 lumenswatt which means LEDs are about 5-6 times more efficient at producing light than incandescent bulbs. Values given in the chart below are approximate.
Lumens to watts calculator Watts to lumens calculation. Conversions are a guide only. Practically though the big difference between lumens and watts is the scale of values.
At 90 deg C emitter output is down 20 80 lumens per emitter. These solar lights are quite heavy and large. How Many Lumens are Needed for Landscape Lights.
