Most professional lights will have far greater output than a standard 60W bulb, but most manufacturers don’t publish the full lumen output of their lights, so it’s difficult to make a direct comparison. The chart shows the lumen count of a traditional light bulb (below).Īs you can see, a standard 60W light bulb outputs 800 lumen. On a light bulb, this value represents the total amount of light coming out of the bulb. A lumen is the standard unit of luminous flux, which is a measurement for the human perceived power of light. If you buy an LED light bulb today, you’ll see two numbers on the box: the wattage equivalent number in big letters and a small number labeled “lumen” at the bottom.
This column is all about decoding that elusive info, making sense of the terminology and hopefully helping you choose the right light for your next project. This is very useful data, though it can be a little hard to decode. The good news is that most LED manufacturers publish photometric data about their lights, charts and graphs informing us how each light performs. They may be comparing overall output, but not specific light levels and beam angles, or only incident light at a disclosed (or often undisclosed) distance, which isn’t exactly helpful when trying to draw comparisons. These comparisons often can be misleading when it comes to professional lights, however. If you dig into product literature, most pro LED manufacturers compare their lights to traditional lighting, i.e., XYZ light is equivalent to a 600W Fresnel light. I just bought a 60W (equivalent) LED bulb for my home, and I chose that bulb because I generally know how much light that outputs. This is also the case when it comes to consumer LED light bulbs almost all new LED light bulbs are described by their wattage equivalent. So it’s not unusual that someone would ask us to describe an LED light in terms of what traditional light it most resembles. It’s not uncommon for someone on set to ask for an ARRI 300, meaning a 300W ARRI Fresnel light. Most of us have used traditional tungsten and HMI lighting, generally described by the wattage of power that it consumes.
#Lumen chart how to
This article explores how to determine what your lumen count is by showing you how to convert watts to lumens. The most common question we get on new LED lighting technology is one asking what traditional lights they compare to, or what does “wattage equivalent light” mean exactly. At AbelCine, we sell and rent several different lighting technologies and do our best to help clients select the right lights for their purposes. With more and more companies producing lights, it can be challenging to decide which might fit your needs. Over the last few years, we’ve seen some major improvements in LED lighting technology in both color quality and output.
