Since there have been several uploads of Winfield lamps this week, here is another.

Winfield was a brand name of products sold by the recently bankrupted British retail chain F.W.Woolworth & Co. Winfield was the middle name of the founder of the company.

This particular lamp was made for Woolworths by Thorn Lighting at the Fylde Road works in Preston. Probably in January 1976 but could be 5 years earlier or later. Its design is similar to the Thorn Netabulb mushroom lamps with coiled-coil filament. However the coating is interesting. It was made by burning a flame of titanium tetrachloride inside the bulb, which produces copious fumes of minutely small particles that are hydrolised to form the white dye titanium dioxide upn contact with the glass bulb. These particles are so tiny that they diffract the light and cause a reduction in the lamp colour temperature, to achieve a warmer white colour even though the coating itself looks white.

I remember the Winfield branded lamps well. Never saved any though, unfortunately

It'll be all right in the end, and if it isn't all right, it isn't the end Smiley
