[MENTION=488078]dwolsten[/MENTION] is correct. No legitimate manufacturer produces a tail light claiming more than 300lm-- and those will often put out less light than a mfr. who makes a better housing and reflector.
I can't find anyone even claiming to use a 500lm red LED element (or combination of elements,) not even the Chinese knock-off lamps. I don't think there's a single-LED tail light out there rated above 150lm.
