Lighting and Electrical Standards
I've given links to some of the standards, but they are copyright so not meant to be shared, and the links tend to come and go. Unfortunately they are also very expensive, so outside of the budget of most potters. If you are lucky enough to have a public library in your neighbourhood, they can often produce the standards for you to read. And if you do want to buy your own copy, it is worth shopping around, as prices can vary significantly.
Lighting
International
The international standard on lamps is IEC 60598. This is implemented in the EU as EN 60598, and in the UK as BS EN 60598.
The standard consists of multiple parts, as given below. Basically 60598-1 includes anything that could apply to any type of lamp, and then in part 2 the various subsections say which parts of 60598-1 apply to that type of lamp, plus sometimes adding in some more specific requirements. So the intention is that you start with the relevant section of part 2, and use that to guide you to the relevant sections in part 1.

USA
The US adopts very few international standards, generally preferring to make their own national standards. Most electrical standards are produced by UL.
The standard for table and floor lamps is UL153 - Portable Electric Luminaires.

There's also an article on wooden lamps in American Woodworker, December 1990 (p. 40ff), which you can read in Google Books here: https://books.google.co.uk/books?id=jPsDAAAAMBAJ&pg=PA40&lpg=PA40&hl=en&sa=X&q&f=false#v=onepage&q&f=false
Electrical Standards
UK
BS767:2018 Requirements for Electrical Installations covers the basis for electrical wiring in buildings, whether domestic houses or work places. It may become relevant if you get involved in designing larger lighting systems for a building, rather than just individual lamps.
