    Lumen output of HID 35W car headlamp versus new single LED 22W 1400 lumen headlamps?

    The thing with LEDs vs HIDs is LEDs can give you so much more bang for the buck. HIDs emit 360 degrees of light in all 3 directions, but only half of that light makes it forward for low beam, and that's assuming the assembly is 100% efficient. I was looking at the 2014 Corolla LED headlight...

    LED headlight experiment, part 2... and a discussion on headlight optics

    Some updates. I got a paper from a manufacturer of LED headlights explaining the challenges and requirements of creating an LED headlight, and how they went out and actually did it for manufacturers www.lpi-llc.com/Papers/SPIE05_5942-13.pdf Here is the ray trace for their end product And...

    LED headlight experiment, part 2... and a discussion on headlight optics

    I am really just looking to see how close I can get from an eyeball observation point of view. I don't have the capabilities to make something that would withstand the rigors of my current wheels (Kawasaki EX650) But I am hoping maybe to parlay this into a masters thesis or maybe even a job...

    LED headlight experiment, part 2... and a discussion on headlight optics

    Initially when I took this on I ran to Ebay to see what was out there. There's two LED retrofit options on the market but both have optical problems. I am sure you guys have seen the shitty "pineapple" conversions with cheap dies just strewn about. Obviously problematic due to the reflector's...

    Got an XT-E drop-in today; first impressions of it and the LED.

    Motorcycle headlights are designed to the same standards as car headlights... they often share components (Hella projectors for example) Problem I am finding with LEDs, at least in traditional configurations, is that they are terrible with spill because of their angular falloff. A...

    Anyone know where can I find a 4300K T6 XM-L?

    I think they have them on Newark dot com I just ordered a bunch from there but I forget what color I got. Some variation of white
