PIAA’s Night-Tech halogen bulb series combines a higher proportion of inert gases with a new filament material designed to deliver up to 90 percent more light than a conventional halogen bulb and a 50 percent longer lifespan. In addition, the Night-Tech’s combination of gases, filament material and glass coatings creates a color temperature in the 3,600 Kelvin range for whiter light and an extended range.
PIAA is offering the Night-Tech bulbs in several formats, including H1, H3, H4, H7 and H11. Each 12V bulb is 55 watts; the H4 Night-Tech is rated at 12V and 60/55 watts.
