LED headlights

I'm looking for recommendations on a replacement headlight for my ZL600. My only experience with LED headlights was a cheap unit that was on a fixer upper bike I bought a few years ago. It was no better, probably worst than a conventional H4 headlight. My goal is for brighter, wider low beam.

   Many words have been written in the adventure bike / sport touring communities re: LED replacements for halogen H4's.  These Riders cover serious miles in all kinds of conditions.  There's also been deep discussion & much research done in the high-performance LED flashlight community re: H4 LED replacements. Their research would be good reading too.   

   Best scenario would be to find a complete 5 3/4" drop in LED unit in which the lens and reflector are designed for the LED emitters within.

   No H4 LED replacement  'bulbs' have earned DOT approval to date.  They can't mimic the point-source of a glowing filament.  The el-cheapo fleaBay and ammzzon devices that promise ten-eighthundred-gazillion Chinese lumens guaranteed !!! cast a glaring beam pattern inferior to that of a H4 halogen bulb in a lens / reflector system designed for same.  Too, many H4 LED devices have heat sinks or fans that make them too deep to fit in a bike headlight shell.

   If unable to source a dedicated 5 3/4" drop-in, search for a shallow LED H4 replacement that can be rotated within it's mount housing to mimic the correct beam pattern / cutoff as closely as possible.

Good Ridin'
