![]() Usually, just the power draw of a light bulb is provided.Īll PIAA halogen headlight replacement bulbs are DOT/SAE Compliant, which means you don’t need to worry about being pulled over by the cops. Most manufacturers don’t provide figures to compare their brightness as PIAA does. These bulbs are rated at 60/55W, equating, in their words, to 110/100W. PIAA also offer their bulbs in a hi/lo form. It’s an interesting claim and hard to corroborate, but the bulbs definitely do put out more light than the previous generation 60W light bulbs. So what PIAA is saying is that their light bulb puts out an amount of light that is equal to what standard halogen lamps would output if they were rated at 110W. This resulted in them putting out more light than the older bulbs. Luminous efficiency refers to the amount of light power emitted compared to how much power the lamp actually draws.Īs lighting technology developed, the bulbs still only drew 60W of power but were much more efficient. However, halogen light bulbs only have around 2-3% overall luminous efficiency. How can this be? A few decades ago, light bulb brightness was based directly on the power rating of the light bulb, and this rating related to how much power the light bulb actually drew. PIAA claims that their bulbs provide 110W of light but only draw 60W.
