This is a general-purpose ceiling light socket fitting. I used it with a Takizumi ceiling light that I have listed separately. It's a general-purpose item, so it can be installed on other manufacturers' lights as well. It has a safety-focused locking function. It is sun-faded. The connector's locking tab is missing. Although you can insert it even without the tab and there shouldn't be any problems in use, it might be better to secure it with tape to prevent it from coming loose. Due to its thickness, I will ship it via regular mail (定形外郵便).
