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. Buy BC or bayonet cap light bulbs from in a range of colours, lumens, sizes and technologies, for domestic and commercial use. ![]() 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. ![]() The outdated metric of using wattage to judge brightness is over, as LED lights use less power to produce the same amount of lumens and can differ according to design. 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. 500 Lumens to watts is typically 5.62 watts using LED, but is dependent on the efficiency of the light source. However, bulbs have moved on, and this is no longer the case. Efficacy is a measure of how well a light source produces visible light. To convert 800 lumens to watts, we first need to know the efficacy of the light source. A 9.6W/m 1K strip creates 816 lumens per meter 85 lm/W. Therefore, Watts naturally became an indication of brightness. An 800 lm flush mount ceiling light requires 10 watts 80 lm/W. 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). Candle Power - (Measured in Candela) - Candle power is an older term used to describe the intensity of light emitted by a source, but it has largely been superseded by the SI unit candela for modern illumination measurements. 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.
