Here is a beautiful new AQUALUX lamp with its box. This is the 3-battery model, lamp approved in 1954 explosion-proof.

Here is the  version   5 AQUALUX batteries. It is a very rare model, no serial number or marking on the base of the lamp because it is not approved explosion-proof like the 3 batteries.

Other  version   5 AQUALUX batteries. One of the first releases in 1954 with white strap, no serial number or marking on the base of the lamp because it is not approved as explosion-proof like the 3 batteries.

The SPIROLUX, the approved explosion-proof flashlight in 3 batteries which will replace the AQUALUX, unfortunately en  aluminum ... therefore not very compatible for underwater use.
