How Do Lumens Per Watt Differ Between Different Types Of Lighting Technologies?

• LED: LEDs stand tall when it comes to energy efficiency. Their intricate design allows them to emit light without wasting much energy in the form of heat. This makes them perfect candidates for both Industrial and Commercial Lighting solutions.

• Halogen: These bulbs produce light by passing electricity through a tungsten filament, which is surrounded by halogen gas. Although they're brighter than traditional incandescent bulbs, their Lm/W is typically lower than that of LEDs.

• Compact Fluorescent: Often recognized by their twisty design, these bulbs are more efficient than both incandescent and halogen bulbs but fall short when compared to LEDs.

• Fluorescent: Commonly used in office settings, these tubes have a decent Lm/W ratio but still fall well behind more efficient LED alternatives.

• Metal Halide & High Pressure Sodium: Both are types of High-Intensity Discharge (HID) lamps. While they produce a lot of light, they are not as efficient as LED solutions, particularly when you factor in their longer warm-up times.

Is More Lumens Per Watt Better?

Yes. A higher Lm/W ratio indicates that the bulb or fixture produces more light for every unit of energy it consumes. This translates to better energy efficiency and reduced energy costs. It's no wonder that so many businesses are now switching to LED Light Fixtures and bulbs.

What's the difference between Lumens Per Watt and Luminous Efficacy?

Luminous Efficacy is the ability of a light source to convert electrical power to light. While they might seem similar, think of Lumens Per Watt as the outcome and Luminous Efficacy as the potential. Both metrics go hand in hand to determine the efficiency of a light source.
