The Different Types Of Lamp Threads And Their Uses
There are many different types of lamp threads available, each with its own unique uses. Here is a quick guide to some of the most common types:
– E26/E27: These are the most common type of lamp threads and can be found on many household light bulbs. They are also known as “standard” or “medium” base threads.
– E14/E17: These are smaller than E26/E27 threads and are usually found on decorative light bulbs.
– GU10/MR16: These are typically used for spotlights and other types of directional lighting.
– B15/B22: These are larger than E26/E27 threads and are usually found on industrial light bulbs and other heavy duty applications.
– Other threads: There are many other types of lamp threads available, each with its own specific uses. Some of the more common ones include R7s, T5, and G9.
How to install a Lamp thread?
Lamp threads are typically very easy to install.
Simply screw the thread into the lamp base using a screwdriver or drill, making sure to be tight enough so that it is secure but not too tight as this could strip the thread. If you are having trouble getting the thread started, you can try using a drop of lubricant such as WD-40.
Once the thread is installed, you can then screw in the light bulb of your choice.
When installing a lamp thread, it is important to make sure that the threads are properly aligned. If they are not, it could cause the lamp to become loose over time and potentially fall off of the base.
Additionally, misaligned threads can also make it difficult to screw in the light bulb, so be sure to take your time and get it right.
Tips For Choosing The Right Lamp Thread
When choosing a thread for your lamp, there are a few things to keep in mind.
First, you need to make sure that the thread is compatible with the base of your table lamps or other lamps.
Second, you need to choose a thread that is the right size for the light bulb and other lamp parts that you plan on using.
And third, you need to make sure that the thread is properly aligned before screwing it into the base.
If you keep these things in mind, you should have no trouble finding the perfect thread for your lamp.
Understanding standard lamp thread sizes
3/8 IPS Thread Dimensions
Lamp threads come in two main different standard sizes, 3/8 inch and 1/4 inch. The size of the thread will determine the fitting that is required for your lamp. To measure the diameter of the thread, use a vernier caliper to measure from the top of the thread to the bottom. Most lamps will have a 3/8-inch thread, however, some may have a 1/4-inch thread.
The American standardization of thread sizes enabled light manufacturing. Designed by the American Mechanical Engineers, this standardization brings unity to the lighting industry.
The system was measured. Frequently 1/8 IP connectors are used on floor lamps, while 14 IP connections are used on floor lamps reflectors and large chandeliers.
Standard size threading provides a standardized connection for different light parts ensuring strong light and stability for lighting.
When replacing the thread in an original lamp, the holder must have a threaded diameter to be accurate.

Measuring for your lamp thread
Once you have determined which type of lamp thread you need, the next step is to measure for it. To do this, you will need to know the outside diameter of the light bulb you plan on using as well as the length of the screw.
To measure the outside diameter of the light bulb, simply wrap a tape measure around it and make a note of the measurement. For the length of the screw, you will need to measure from the top of the screw to the bottom.
Once you have these measurements, you can then determine which size thread you need.
