What does keyless mean on a keyless lamp holder?

A keyless lamp holder is a type of light fixture that does not require a physical key or a traditional light bulb socket to operate. Instead, it typically uses a simple twist-and-lock mechanism or a push-and-pull design for inserting and removing bulbs. This design allows for easier bulb changes and can accommodate various bulb types without the need for a specific key. Keyless lamp holders are often used in fixtures where ease of access is essential.
