The Night-Tech bulb features several advancements in performance, durability, and manufacturing Through the use of a unique mix of gasses including a higher proportion of inert gasses 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 gasses, filament material, and coatings on the bulbs offer a color temperature in the 3600 Kelvin range for a whiter output than standard bulb and still retains a DOT/SAE approval The unique dual band bulb coatings not only create a whiter light but a brighter, longer range (up to 35 meters) output when compared to other bulbs The new gas mixture, filament material, as well as manufacturing processes such as using gold plated contacts gives high performance and great looks as well as extending the life span by up to 50%
