Why do fittings have different bases?
Light bulbs have to fit snugly into light fixtures, so they are designed with different bases. The light bulb base has to match the socket in the light fixture. If light bulb bases were standardized, light bulbs could be interchangeable across many fixtures. However, light bulb bases are not standardized. This is to prevent dangerous light bulbs from being used in light fixtures that aren’t designed for them. Light fixture sockets have a grip on the inside of the socket, and light bulb bases have a matching metal tab on the outside of the base. A light bulb with no grip can be inserted into any kind of light fixture, but it won’t stay in place because the grip and tab don’t match up. This is why light bulb bases aren’t standardized: if they were interchangeable across light fixtures, people would risk inserting a light bulb into sockets that weren’t designed for them.
What is a mini bipin?
