The black out
The black out which occurred in the United Kingdom during World War Two made it a place hostile towards led gu10 bulbs! Frustrating enough for households, imagine how difficult it was to make shops and factories emit no light! It was extremely difficult for factories that had large glass roofs to install the blackout panels and all the permanent methods for blacking out light, such as paint, meant that no sunlight could enter during daylight hours. Shops installed double “airlock” doors which stopped light escaping when customers departed or arrived. Civilian ARP wardens would patrol the Unite Kingdom ensuring that no building were emitting even the slightest bit of light and heavily penalized any offenders.

The blackout did succeed in lessening German successful attacks. There was no expected increase in crime rates. In 1944, as the war drew to a close, a “Dim-out” was introduced which allowed lighting equivalent in strength to moonlight to be introduced. If an alert was sounded, a full Blackout would commence. On April 30th 1945, Big Ben was lit after 5 years and 123 days of being extinguished – the duration of the Blackout.
