The Luz primarily was to have three versions: ship-to-ship, coast-to-ship and air-to-ship. The latter was dropped quite early in the missile development, so the two other remained, the coast-to-ship actually entering service with 422th Artillery Battalion, but never used operationally during the 1967 war, after which it was retired.
The ship-to-ship variant was to arm Israeli Z-class destroyers (and perhaps ships that would enter service later). Each destroyer was to have two fixed lanchers in the bow and two trainable triple launchers replacing torpedo tubes (eight launchers in total). The fixed launchers would fire missiles during closing the enemy, others would fire their missiles while the ship would be at closer range from the enemy manoeuvering during battle. The missile's warhead was an equivalent of the 8-inch gun projectile, that would give the Israeli ships quite a punch against the Skoryi-class destroyers of the Egyptian (and perhaps Syrian) navy. Guidance obviously was based upon optical tracking and manual joystrick-steering. The Israeli navy wanted something that could have been used in night or inclement weather, and that could been fired in salvos (CLOS guidance meant sigle-channel system; a destroyer might have had more than one guidance station, but this is my pure speculation), so demanded some sort of a radar guidance. That demand was rejected by the Israeli treasury, for it was considered (quite rightly) more expensive than simple optical system.
Trial firings from destroyers proved that the navy had been actually right. To manually steer the missile from a ship, even while the system had a stabilisation mechanism in it, was almost impossible. Taking into considerations the Luz's operational limitations (day-only use, no salvo-firing etc.) the system was rejected and a decision to built an advanced radar-guided replacement, which soon became the Gabriel, was made. Meanwhile the Israeli navy developed a concept of the missile boat, so the new missile was to arm that class of ships, not destroyers.
Below you'll find photos of the Luz and its box launcher that was developed to be mounted on destroyers (note that the later Gabriel launcher was quite different) as well as photos of a trial installation on an destroyer.
