Bright vs Safe—Why Most LED Bulbs Get Beam Pattern WRONG! | Diode Dynamics

https://www.youtube.com/watch?v=VUz8WxPiUhs​

In this video, we show why beam pattern matters more than getting the brightest possible output. Your car's headlights are built to focus light where you need it most. If the bulb is out of focus, it won’t matter how bright it is—it’ll cause glare and light up the foreground instead of the road ahead. That’s where the SL2 Pro LED comes in. It’s designed to match your original beam pattern for better focus and visibility while delivering more output.

Some LED bulbs over-focus, creating streaks and harsh cutoffs, but the SL2 Pro strikes the perfect balance—focused, bright, and smooth.

Both the SL2 and SL2 Pro LED Replacement Bulbs are backed by an industry-leading limited LIFETIME warranty.
