Don't get me wrong. Lexus have some of the best LED headlights, I've seen them. Are they more effective than HID/xenon? YES+
Flux in Beam. Anyone capable of designing optic formulas for any given color/temp per lumen requirements will also be able to design the ultimate projection lens. Give me $1,000,000 and 12months! Lexus and others have already done it apparently.... they are not using the $9.99 leds tech that we all see on Amazon I promise you
(lots to learn my man)
For now, for us, 55w halogen has more lumen output than those leds
