How to choosing the right energy saving corn LED lamp to replace mercury lamp?
Brightness—Making sure it’s bright enough Obviously, the first factory that comes to mind when we think of a bulb’s performance is brightness. Shop for lumens, not watts, same watts higher lumen output is better. Watt are a measure of how much energy the bulb draws, not its brightness. For example: A 125W HWL mercury lamp will output 1625 lumens, A 120W LED corn light will output 16530 lumens, taking a look at efficacy, which is simply found by dividing the lumen output by the wattage necessary to power the bulb, the mercury lamp outputs 13lm/W while the LED corn bulb achieved 130lm/W. LED corn light also are rated by watts. But that’s no help because there’s no easy way to compare LED watts with HID, MH, HPS, and CFL lamp’s watts. Here isn’t a uniform way to convert traditional lamps’ watts to LED watts. Now, instead of watts, use lumens as the yardstick of brightness. Packing on LED bulbs rates brightness in lumens ( and in watts). To replace a 250W mercury lamp, look ...
