Gregg: The new Hunza Path Lite Surface mount is not meant to compete with or replace "Drive over" fixtures. If you need a drive over then purchase a drive over. I need a surface mount fixture for lighting residential docks and some deck applications. For these we need a small, discreet, yet effective fixtgure that is shielded and does not require a core mount. Sean: The top is the same as the PL fixture, the difference is that the new unit is a surface mount and not an in-ground or core mount.
