The Night Tech line of high output replacement bulbs from PIAA features several advancements in performance durability and manufacturing. Through the use of a unique mix of gasses including a higher proportion of inert gases as well as a new filament material these bulbs offer up to 90% more light than a conventional bulb with a greater life span. The gases filament material and dual band coatings on the bulb offer a color temperature in the 3600 Kelvin range for a whiter and brighter light. It also has a longer range (up to 35 meters) output when compared to other replacement bulbs and still retains SAE/DOT compliance.
