Brightest LED Bulb: Watts vs. Lumens vs. Luminous Efficacy
Jul 22, 2019
If you have always purchased incandescent or other types of light bulbs other than LEDs, then you probably understood that the higher the wattage, the brighter the light. But, while that may have generally been true, it is no longer true anymore. To find the brightest LED bulb takes more than just a search for the highest wattage, and looking at things other than the wattage offers some advantages. The following is a quick look at why watts are no longer the go-to and what else to consider when researching and purchasing the brightest LED bulb for your company’s lighting system:
The Brightest LED Bulb: Watts vs. Lumens vs. Luminous Efficacy
Watts. Watts are the unit used to measure how much power a light bulb consumes. With incandescent lights, there is a direct correlation between power consumption and brightness in that traditionally the more energy a light bulb consumed, the brighter the light it would produce. This is where the adage of more watts equals brighter lights comes from.
Lumens. Lumens are the unit used to measure the total light a bulb emits or, in other terms, the precise brightness of a bulb. The more lumens listed by a bulb, the brighter the light you can expect (and the inverse is true, the lower the lumen, the dimmer the bulb). Currently, the brightest LED bulb used for general use is rated at 5500 lumens (although there are some consumer flashlights sold with higher lumen ratings).
Luminous Efficacy. Unfortunately, there is no direct conversion from watts to lumens due to LEDs being more efficient and requiring less power to put out more light than traditional incandescent bulbs. But there is luminous efficacy. Luminous efficacy is the ratio of lumen output to watts consumed. A good way to think about luminous efficacy is in terms of automobiles and fuel economy in that you want to get more lumens (mileage) out of as little wattage (fuel) as possible.
Shopping for Your Next Light Bulb and Lighting System
With a grasp on the difference between watts, lumens, and luminous efficacy, you will find shopping for your next lightbulbs a breeze and while there is no direct conversion, there are plenty of guides to help steer you in the right path when making the change from incandescent light bulbs to LEDs. For example, for most brands of incandescent lightbulbs, a 40-watt bulb will produce 450 lumens. That bulb can typically be replaced by a LED bulb rated at between 6 and 10 bulbs. This means that typically a LED bulb in this scenario will cost about 25% less as the equivalent incandescent bulb — which can really add up when you multiply that by every bulb in your business!
