Just like fire glows red/yellow at low temperatures and blue/white at higher temperatures, bulbs act the same way. The more wattage a bulb uses, the brighter [and whiter] it will be. The average store-bought bulbs shine yellow light because they have low wattages with no “designer” brand technologies. That’s where PIAA and Nokya come in; both of those brands have taken multiple steps to make their bulbs better, more powerful- and they do it by changing the lens color and wattage. Nokya and PIAA both have found a way to increase light output (i.e. wattage) without requiring the bulb to demand more power from your system, which is the first step in creating a white light. Next, PIAA applies special lite blue and violet coa
