To establish how much light you’ll need in a room, it’s important to measure a bulb’s output of light. The best way to do this is with lumens – the total amount of visible light from a source. As a general rule, it takes around 20 lumens per square foot to create appropriate ...
CFLs provide much more light at a fraction of the wattage of traditional bulbs. Because of this, CFLs are often categorized by lumens. Lumens measure the amount of light a bulb gives off, making this measure a more accurate way to tell how bright the new bulbs are in comparison to the ...
Felix:What are you looking at to measure something like digital customer experience? Brian:We A/B test everything, not everything–but the important things. If we're making a change, we run A/B tests to understand whether or not the test is the same, better, or worse than the control...
When it comes to choosing the right light bulb, understanding the difference between lumens and watts is crucial. While lumens measure the brightness of a bulb, watts indicate the amount of power it consumes. Let’s delve deeper into the distinction between these two terms. Lumens, as previousl...
Starting a business is a pursuit that appeals to many, but not everyone knows where to start. This guide will walk you through the elements of starting a business and explain what you can expect as you embark on the journey.
