Here is a question about this article: Lamps designed for different voltages have different luminous efficacy. For example, a 100-watt, 120-volt lamp will produce about 17.1 lumens per watt. A lamp with the same rated lifetime but designed for 230 V would produce only around 12.8 lumens per watt, and a similar lamp designed for 30 volts (train lighting) would produce as much as 19.8 lumens per watt. Lower voltage lamps have a thicker filament, for the same power rating. They can run hotter for the same lifetime before the filament evaporates.
What is the answer to this question: How does filament size relate to voltage level?
****
So... Lower voltage lamps have a thicker filament

In 1936, Wever was killed in an air crash. The failure to implement his vision for the new Luftwaffe was largely attributable to his immediate successors. Ex-Army personnel Albert Kesselring and Hans-Jurgen Stumpff are usually blamed for the turning away from strategic planning and focusing on close air support. However, it would seem the two most prominent enthusiasts for the focus on ground-support operations (direct or indirect) were actually Hugo Sperrle and Hans Jeschonnek. These men were long-time professional airmen involved in German air services since early in their careers. The Luftwaffe was not pressured into ground support operations because of pressure from the army, or because it was led by ex-army personnel. It was instead a mission that suited the Luftwaffe's existing approach to warfare; a culture of joint inter-service operations, rather than independent strategic air campaigns.
What year did Wever die?
1936
