![]() In the example above, the ScreenBar is measured at 320 lumens (a little less than a traditional 40-watt bulb) but because it focuses its light around the desk area and not the monitor – it is quite bright on the desk – measuring 1000 lux from 45 cm high. ![]() The technical measurement for this is called “lux,” where the brightness is measured in the center at a specific height. For example, the BenQ ScreenBar desk lamp sits above the monitor and creates a light pattern that looks like a sideways “D,” which directs the light onto the desk – but not on the monitor. But with LED’s a good designer can create a custom shape without too much difficulty to make the light work harder. Again, for incandescents – the light usually went everywhere. The other component is how the lamp distributes the light. You can find out how to avoid them below.

The Lumens to Watts conversion table shows LED bulb Wattage in relation to approximate Lumens produced: LEDįor further information on selecting the best fit LED lights to suit your needs, speak to a member of our expert LED lighting team today. How many Lumens do I need? In order to provide adequate lighting for a standard living space of 250 sq ft, you should invest in lighting solutions that emit around 5,000 Lumens. In contrast, Wattage gives an accurate description of the power supplied to the bulb and says nothing of the bulb’s luminosity. Quick Answer: Lumens give an accurate measure of light, regardless of Wattage. In this scenario, the increasing Wattage means nothing, as the brightest bulb is actually the lower Wattage LED, and the most dim bulb is the highest Wattage Halogen bulb. This presents some consumers with something of a puzzle when faced with a choice between a 13W LED bulb, a 15W CFL bulb, and an 18W Halogen bulb. Due to the overwhelming longevity and energy efficient benefits of installing LED lights throughout the home, LEDs have quickly taken over as the savvy choice of domestic bulb. However, bulbs have moved on, and this is no longer the case. Therefore, Watts naturally became an indication of brightness. The reason for the confusion is that traditional - and now largely obsolete - incandescent bulbs emitted light by means of passing electricity through a suspended filament that burned at a higher temperature and brightness in correlation to the greater amount of Watts being passed through it. So why did we ever use Watts to measure brightness in the first place? We didn’t. The greater the Wattage, the higher the power supply to the bulb (which technically says nothing about the expected brightness). What are Lumens? Firstly, Wattage measures power not brightness. But what are lumens? And why has Wattage been abandoned as the standard unit of brightness? How are we supposed to gauge which bulb to use? Luckily, we’ve put together a Lumens to Watts chart, because Lumens are the new measure of brightness and they’re here to stay. If you have recently purchased a light bulb, you may have noticed a switch on the packaging from Watts to Lumens.
