So why are so many lights often labeled or include the wattage as a model name?&nbsp;<\/p>\n\n\n\n<p class=\"has-black-color has-text-color has-link-color wp-elements-2 wp-block-paragraph\">Well this mainly has to do with the electricity and often when using a lot of strong lights with also a strong power draw, you have to be careful not blow a fuse by drawing too much wattage. So knowing how much wattage the lights are you can easily calculate them together to for example not exceed 2000watt in one group in a building or in a house.<\/p>\n\n\n\n<p class=\"has-black-color has-text-color has-link-color wp-elements-3 wp-block-paragraph\">What does stand for the brightness of the light is either Lux at 1 meter or lumens, which I have noticed not a lot of Youtubers refer to the brightness of light with and often uses odd methods to show how bright a light actually is, without using an international standard.<\/p>\n\n\n\n<p class=\"has-black-color has-text-color has-link-color wp-elements-4 wp-block-paragraph\">The reason to use Lux is that it is an international standard unit to measure brightness, but also when you really start comparing the Lux of different lights with the same wattages, you will find out that a lot of them don\u2019t output the same level of brightness.<\/p>\n\n\n\n<p class=\"has-black-color has-text-color has-link-color wp-elements-5 wp-block-paragraph\">For example&nbsp; the Rollei or Colbor W100 vs the Zhiyun Molus X100, both are 100 watt lights, but the amount of light coming out of both of them are very different.<\/p>\n\n\n\n<p class=\"has-black-color has-text-color has-link-color wp-elements-6 wp-block-paragraph\">Rollei W100 peak brightness is 7400 Lux at 1 meter, while the Zhiyun Molus X100 peak brightness is at about 17.000 Lux at 1 meter, which is clearly more than just double its brightness, while both lights draw about the same amount of power.&nbsp;<\/p>\n\n\n\n<p class=\"has-black-color has-text-color has-link-color wp-elements-7 wp-block-paragraph\">While a traditional 800 Watt Redhead you might think is going to be way brighter than 60 watt light. A 800 watt Redhead gives you about 21.000 Lux at 1 meter, but my Nanlite forza 60 with a spotlight attachment gets about 30.000 lux at 1 meter, while drawing far less power.<\/p>\n\n\n\n<p class=\"has-black-color has-text-color has-link-color wp-elements-8 wp-block-paragraph\">And also to understand the Lux value a bit better, there is an illuminance list which you can refer to to find out how bright of a light you likely need.<\/p>\n\n\n\n<p class=\"has-black-color has-text-color has-link-color wp-elements-9 wp-block-paragraph\">Bright Sunny day its 32.000-100.000 Lux<\/p>\n\n\n\n<p class=\"has-black-color has-text-color has-link-color wp-elements-10 wp-block-paragraph\">In the shade with clear blue sky 10.000 &#8211; 25.000 Lux<br>Overcast is 1000-2000 Lux<\/p>\n\n\n\n<p class=\"has-black-color has-text-color has-link-color wp-elements-11 wp-block-paragraph\">Office lighting 300-500 Lux<\/p>\n\n\n\n<p class=\"has-black-color has-text-color has-link-color wp-elements-12 wp-block-paragraph\">You either want to match the Lux numbers or if you want to over power the lights you need a light with a much higher Lux output.<br><br>One issue I have with Lux is that the values get quite large making it less easy to remember and also a mouth full to say numbers that are above 10.000 lux.&nbsp;<\/p>\n\n\n\n<p class=\"has-black-color has-text-color has-link-color wp-elements-13 wp-block-paragraph\">There is a Foot-Candle unit which has a smaller value, however it isn\u2019t an international standard of measuring unit, so that is why I don\u2019t think this is a proper way to show the brightness of a light. A measuring unit that is an international Standard is KLX which stands for Kilolux.<\/p>\n\n\n\n<p class=\"has-black-color has-text-color has-link-color wp-elements-14 wp-block-paragraph\">And 1 unit of Kilolux is a 1000 Lux, which should make things a lot easier to understand with smaller numbers.<\/p>\n\n\n\n<p class=\"has-black-color has-text-color has-link-color wp-elements-15 wp-block-paragraph\"><br>For example the Zhiyun Molus X100 is 16.985 lux and saying that it&#8217;s quite a hassle with too many numbers, while just saying 17 kilolux is a lot easier.<\/p>\n\n\n\n<p class=\"has-black-color has-text-color has-link-color wp-elements-16 wp-block-paragraph\">Also adjusting the illuminance list with smaller numbers makes it easier to understand.<\/p>\n\n\n\n<p class=\"has-black-color has-text-color has-link-color wp-elements-17 wp-block-paragraph\">Bright Sunny day its 32 &#8211; 100 Kilolux<\/p>\n\n\n\n<p class=\"has-black-color has-text-color has-link-color wp-elements-18 wp-block-paragraph\">In the shade with clear blue sky 10 &#8211; 25 kilolux<br>Overcast is 1-2 Kilolux<\/p>\n\n\n\n<p class=\"has-black-color has-text-color has-link-color wp-elements-19 wp-block-paragraph\">Office lighting 0.3-0.5 Kilolux<\/p>\n\n\n\n<p class=\"has-black-color has-text-color has-link-color wp-elements-20 wp-block-paragraph\">So in the future when I review lights I will be using Kilolux instead of using just Lux.<\/p>\n\n\n\n<p class=\"has-black-color has-text-color has-link-color wp-elements-21 wp-block-paragraph\">Hope lighting companies also would look at this and also enable them to show the brightness of their lights using KLX for Kilolux, with much smaller numbers that are far easier to remember and also they don\u2019t need to type in large numbers to display on their website.<\/p>\n\n\n\n<p class=\"has-black-color has-text-color has-link-color wp-elements-22 wp-block-paragraph\">If you agree or disagree leave a comment below.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Stop saying Watt as if it&#8217;s the brightness of the light, Watt is just the power draw of the lights, two lights with same wattage can have a totally different level of brightness output.
