I grow less and less fond of Hyperikon every day. They just do ****** things as a company that pinch my pickle. In this case, they list their 4000k fixture as "daylight glow". This is an obviously misleading name to fool the unwary customer into thinking that this is the "daylight" color that alot of users are told that they should look for. Industry wide, 5000k has been adopted as "daylight" color. Alot of folks that buy these fixtures in 4000k "daylight glow" are going to be disappointed when they get them installed.
Folks.... never, ever, ever look at the words that describe the lamp's color! Always use the Kelvin number (K) to compare colors...and this is an example of the exact reason why. Crappy companies trying to dupe you.
We all see differently, so things appear differently to each of us. But most people would say that 4000k is as white as white can be. It is the most popular color sold in the USA. 5000k starts getting into the blue range and is really popular with folks who work in shops and factories.
