Stella, the reliable lamp : advert issued 1963
From the Scottish Municipal Annual of 1963 - Stella, the reliable lamp. Addresses in both Giffnock and Shaftesbury Ave., London, are given but Stella was in fact a subsidiary company of Philips Electric. In the surprisingly murky world of lamp and bulb manufacturing, that in the inter-war years was amazingly complex in terms of brands, ownerships and trade 'agreements' and cartels, this arrangement was not uncommon!
The advert shows a range of street lighting equipment, including the control gear, for the seemibly bright white light of mercury discharge. It used to be a real thing, the difference between varying local authorities, as to whom used this 'white' light and the 'orange' of sodium discharge!
