Designed for war-time use. All lanterns compiled with BS/ARP 37.

Existing electrical lanterns could be modified with conversion fittings (such as by GEC or REVO) or be replaced with ARP compliant fittings.

It was decided that gas lanterns could be modified and fitted with an auxiliary burner which complied with BS/ARP 37. This was called the Standard Gas Industry fitting. No specific ARP gas lanterns were produced. To meet the requirements for different mounting heights and types of lamp, well over 50 variations of the unit and the adaptors were supplied.

In 1944, the Gas Industry developed an entirely new low-output burner which could be used as a conversion unit in square lanterns. It produced light to the ARP specifications, but used about a third of the gas used in earlier units, and required only about a fourth of the amount of metal used for standard fittings.

Regulations were relaxed in September 1944 in what became known as the "Dim Out" or "Moonlight Lighting". Few manufacturers supported this new lighting as it was seen as a short prelude to the restoration of pre-war lighting.
