But to find a good relationship between the factors Lumens > Lux > Candela all need to precisely interact within the Filmic color management to get a close to an accurate representation of the real world values. A conversion from Watt’s/Square meter is easy. Just enter the lumens value and select the light source to get the corresponding watts value. A good formula is needed to take different factors in to matter. Call 0333 77 22 111 or visit the LED Hut blog page for social media details. This is an online calculator to convert lumens to watts. 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. The theoretical maximum for green LEDs is 683 lumens per watt but as of 2010 few green LEDs exceed even 100 lumens per watt. Luminous flux in lumens (lm) to electric power in watts (W) calculator and how to calculate. 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. Buy BC or bayonet cap light bulbs from in a range of colours, lumens, sizes and technologies, for domestic and commercial use. 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. You may find yourself comparing LED grow light specifications, where one light uses lumens and the other uses PAR. If you have recently purchased a light bulb, you may have noticed a switch on the packaging from Watts to Lumens. About the Lumens to PPF (umol/s) Calculator.
