Although we all perceive light in a different way and personal tastes vary, there are some scenarios where most people agree on the most appropriate lighting type. White light is preferred for many reasons. There are three main types of regular light bulb – CFLs (compact fluorescent lamp – the standard type of energy-saving light bulb), halogens or LEDs. (like 4000k color temperature light) Cold White: This daylight color temperature are best suitable for offices, workshops, bathrooms or other areas where high detail visibility is important. Blue light is a form of cool light on the vision spectrum that produces a lot of energy.
