I am looking to buy some solar lights to mark a path (with full
knowledge that they are not nearly as bright as wired lights).

It seems though that light brightness/duration and the quality of the
fixtures themselves (cheap plastic vs. thin coated metal vs. heavy
duty metal etc.) vary widely.

I have not been successful in finding any good quality reviews and
comparisons of alternative brands and models.

So does anybody know of any brands, models, retailers etc. that are
high quality and give state-of-the-art light output.

Thanks
