![]() In the past, we commonly bought conventional bulbs on the basis of wattage. For our lightbulbs, the lumen defines the perceived brightness of a specific bulb (such as an LED fixture). The Lumen is a measurement of light output. Innovation has led us into updating how we rate and reference our bulbs. Perhaps the most recognisable one, which has existed for decades, is the wattage. If you’d like to see our full range of LED bulbs and LED lighting-related products, why not pop over to our LED lights online store.When buying lightbulbs, you'll see commonly see several measurements listed on the packaging. So, hopefully, the next time you’re searching for a replacement light bulb, you’ll buy one that’s brighter, longer-lasting and more energy-efficient, and that means you’ll be buying an LED! Producing a lot less detrimental heat than incandescent bulbs enables LEDs to achieve a 50,000 hour lifespan, so they’ll still be going strong in about 17 years’ time! This massively reduced power requirement is literally “brilliant” for you as a buyer, because it not only means you’ll be getting a replacement light bulb that will cost you 90% less in terms of electricity, you’ll also benefit from the fact that LEDs have a considerably longer life-expectancy as well. This is why one of our pictured Dimmable E27 Omni-LED Clear Globe Bulbs can produce the same 650 lumens of light as the 60 watt incandescent it’s designed to replace. LEDs have the highest lumen-to-watt ratio of any type of lighting, which means they’re capable of producing a large amount of light for comparatively little energy. Bulbs that produce more lumens-per-watt are a great deal less expensive to run, as they generate more light for less power. The rate at which light bulbs convert watts into lumens varies considerably between different technologies. ![]() The effectiveness of a bulb can be expressed by its lumen-to-watt ratio or, in other words, the number of lumens it produces for each watt consumed. So when you’re purchasing a light bulb, ask yourself whether you’re buying electricity or light, and if it’s light you’re after, go for the packaging that displays the greatest number of lumens, requiring the fewest number of watts. ![]() The number will be displayed on the bulb’s packaging, as you’ll see from the picture of one of our bulbs. When purchasing light bulb these days, always check out its Lumens. The belief that a 100 watt bulb must be twice as bright as a 50 watt bulb has been our traditional purchasing criterion for many years, however, the reality of the situation is that the former merely sucks up more power than the latter and, in the case of LEDs vs Incandescent bulbs, for little or no payback. But, as stated earlier, this is becoming a much less reliable indicator as time marches on. People constantly make the mistake of believing that the number of watts denotes a bulb’s light output. Watts don’t necessarily measure the brightness of a bulb, only the amount of electricity it uses. Therefore, the greater the number of Lumens, the brighter the light will appear. In simple terms, Lumens (lm) are a measurement of the light that’s emitted by a lamp or bulb which is visible to the human eye. Thus, the lighting industry has now opted to use a more stable and widely-regarded unit for measuring the intensity of light, and that’s where Lumens enter the story. Unfortunately, this rapid development means that the traditional “Watt” measurement has become less and less able to accurately denote the brightness of a bulb.įor example, one manufacturer might proudly unveil their 4 Watt LED Bulb to replace a 30 Watt Incandescent bulb, only for it to be superseded a couple of months later by another, whose 4 Watt LED will replace a 60 Watt. LEDs are at the forefront of current lighting technology and are developing and improving in efficiency. ![]() The emergence of energy-efficient LED light bulbs in the last few years has made choosing bulbs to replace your existing, wasteful incandescent bulbs a lot less simple than it used to be.
