LUMENS: THE NEW WAY TO BUY FOR LIGHT

For most of people, they bought lights based on how much energy, or watts, they use. Wouldn’t it make more sense to buy lights based on how much light they provide?

When you’re looking for lights, you can choose the lights for the brightness you want by comparing lumens instead of watts. A lumen is a measure of the amount of brightness of a light — the higher the number of lumens, the brighter the light.

WHAT ARE WATTS?

Watts measure the amount of electrical power used to light a bulb. Essentially, by that definition it means that the more watts a bulb show the more power it will consume to produce light.

WHAT ARE LUMENS?

Lumens measure how much light you are getting from a light. The lumen is often misinterpreted as the watt, which is inaccurate. The watt is the measure energy which, when supplied to a bulb, produces luminous light. The brightness of this light is measured in lumens. More lumens mean it’s a brighter light; fewer lumens means it’s a dimmer light.

Lumens are to light what

  • Pounds are to apple
  • Gallons are to milk

Lumens let you buy the amount of light you want. Because Watts just tell you the power bulbs consume to produce light, while lumens portray the brightness of light.

WHY THIS IS IMPORTANT TO SOLAR LIGHTING?

Solar lighting needs to take into consideration both the Lumens and the Wattage of a lamp. The wattage provides the needed power from the solar power and battery system to power the solar light fixture for the required amount of time and the Lumens determines how much light is given off by the lamp. The more efficient the fixture or lamp is, the more efficient the solar and the lower the cost of the complete system.

 

 

Higher Lumen and lower Wattage lamps, especially with LEDs, will provide the best lighting with the lowest energy costs. So when buying your new lights, think lumens, not watts.
