Which is brighter 4000K warm light or 5000K cool light?

Actually if you check the specs for the fixture you are looking at and both versions have the same Lumens value neither of them should be brighter but they should provide the same amount of light and illumination, the only difference is the color feeling. It could be a bit confusing some manufacturers may call 4000K “daylight” and 5000K “cool-light”, that is just a way to try to describe the difference in color and feeling, in words the main difference is that 5000K has more blue light in it and that is why it is considered “bright white” or “true white” color temperature, on the other hand 4000K as it has less blue in it, this color temperature provides a warmer feeling and looks more yellowish compared to 5000K.
What color temperature to choose? Well it mainly will depend on the customer’s or user’s preference. If it is the same type of fixture and the only difference is the color temperature version (4000K or 5000K) they should provide the same amount of light and lit up a surface or space the same. As a general suggestion 5000K is better recommended for warm weather locations, most customers prefer 5000K to use that color temperature in their shops or stores because it provides a bit more accurate color perception for products retailing. 4000K is better recommended for cool weather locations and for full of activity and family areas.

As we mentioned the Lumens value is what determines the brightness of a light fixture. The higher the lumens value, the brighter the light fixtures will be. Depending on energy efficiency, the higher the wattage, the higher the Lumens value, this is especially true for LED fixtures. Great examples for this are Hero Series LED High Bay Lights with energy efficiency rate of 140 Lumens per Watt. So with a 100w Hero Series LED High Bay Lights you get 14000 Lumens, with a 150w one 21000 Lumens, with 200w it produces 28000 Lumens and with 250w 35000 Lumens. Hero Series LED High Bay Lights are a type of industrial and commercial fixtures with a lifespan of over 60,000 hours of operation and come with a 5 year warranty against quality issues; they are available in 5000K and 4000K. Hero Series LED High Bay Lights are easy to install, they come with a standard US Hook, safety wire, 5ft cord and standard 110v plug. As an important spec Hero Series LED High Bay Lights come with the dimming feature. To use Hero Series LED High Bay Lights dimming feature you would need to connect the two low voltage wires coming out of the top of the fixture (a gray and purple one) with a 1-10V Dimmer, using 18 or 16awg gauge wire.
