the glass gets hot but it does not matter there is no reason one should need to touch the bulb, especially when its new.
Socket
If the 250 watt bulb is a HID or similar type the ballast comes complete with the fixture. The bulb socket is also part of the fixture and comes pre-wired to the socket. To connect the bulb to the fixture all that has to be done is just screw it into the fixture's socket.
The thing that a bulb goes into is called a socket. It is the part that connects the bulb to the electrical supply in lighting fixtures.
Technically speaking a bulb and a lamp are the same thing. You can use a 60 watt bulb in a fixture calling for a 40 watt bulb but I wouldn't. The lighting fixture may get to hot, melt and start a fire.
Replace bulb and check socket for ground and Hot
It is called a socket.
No, it is not safe to remove a metal part of a light bulb that is stuck in the socket. It is recommended to turn off the power and seek professional help to avoid the risk of electric shock or injury.
HERE'S AN EXAMPLE: IF THE POLARITY IS BACKWARDS AT A LIGHT FIXTURE THEN THE HOT (120VOLTS) WILL BE THE OUTSIDE OF THE LIGHT BULB SCREW SHELL AND THE MIDDLE PRONG INSIDE THE SOCKET WILL BE THE NEUTRAL -- THEREFORE WHEN YOU CHANGE THE BURNT OUT LIGHT BULB YOU WILL GET SHOCKED BECAUSE THE SCREW SHELL PART IS HOT!! IF WIRED CORRECTLY YOU WILL NOT GET SHOCKED BECAUSE THE HOT (120VOLTS) WILL BE INSIDE THE SCREW SHELL ON THE PRONG AND YOU WON'T BE TOUCHING THAT PART WHEN YOU CHANGE THE LIGHT BULB!!
To remove the metal part of a light bulb, first make sure the bulb is turned off and cool. Then, carefully twist and remove the metal base of the bulb from the socket. Be cautious not to break the bulb or hurt yourself in the process.
If a bulb breaks in the socket, first turn off the power to the socket. Use gloves and pliers to carefully remove any remaining pieces of the bulb. Then, replace the bulb with a new one and make sure the socket is clean before turning the power back on.
It is called a socket or base. This keeps the bulb securely in place and allows electricity to flow directly to the bulb.
It is not recommended to use a 120 volt bulb in a 130 volt socket as it can cause the bulb to burn out faster or even lead to safety hazards. It is important to match the voltage rating of the bulb with the socket for optimal performance and safety.
