Light bulb

Redirect to:

This page is a redirect. The following categories are used to track and monitor this redirect:

From a related word or phrase: This is a redirect from a word or phrase (term) to a page title that is related in some way. This redirect might be a good search term, or it could be a candidate for a Wiktionary link.
- Redirects from related words are not properly redirects from alternative spellings of the same word. They are also different from redirects that are subtopics or related topics, because unlike those, a related word or phrase probably does not warrant its own subtopic section in the target page or possess the possibility of ever becoming an article, template, project page, and so forth.

From a page move: This is a redirect from a page that has been moved (renamed). This page was kept as a redirect to avoid breaking links, both internal and external, that may have been made to the old page name.

From an avoided double redirect: This is a redirect from an alternative title or related topic of Lamp (electrical component), another redirect to the same title. Because double redirects are disallowed, both pages currently point to Electric light.
- If Lamp (electrical component) is retargeted or is expanded into a separate article, template, or other project page, this redirect will be recategorized to be updated.

From a cross-project redirect: This is a redirect from a title associated with an item on Wikidata. The Wikidata item associated with this page is light bulb (Q1318740).
- Use this template only on hard redirects – for soft redirects use {{Soft redirect with Wikidata item}}.

When appropriate, protection levels are automatically sensed, described and categorized.
