I'm not sure anybody has a dream of becoming a lighting scientist when they're a kid. It actually started out as a summer job at the university where I went to school. And I actually thought it was the Lightning Research Center, which seemed a lot more exciting. I was a little disappointed when I learned it was lighting.

But as I learned more about it, it really became something that was interesting to me about light that's all around us. And it affects not only the way we see, but the way we sleep and a lot about our health and well-being. And it hasn't gotten boring after 30 years.

Well, there's two ways to answer that question. But fortunately for your listeners' sanity, the answer is yes to both of those. The first way has to do with the color of LED headlights. You've probably noticed that a lot of them look a lot more of a bluish white compared to the yellowish white of halogen headlights.

And the way that we define light, the definition of light, when we measure it, is actually over 100 years old. And it actually discounts a lot of the blue wavelengths, the blue part of the color spectrum. So in that sense, even though the light meter may say two headlights are equal, our eyes will see the LED bluish one as brighter.

The second way to answer that question is to actually use the light meter and measure Intensity of headlights have actually increased over the last 10 or 20 years.

It's actually both kinds of headlights. Both the halogen headlights and the LED headlights have increased in their luminous intensity.
