Difference Between Shunted And Non Shunted Lamp Holders
Difference Between Shunted And Non Shunted Lamp Holders. A shunted socket has two holes and receives two wires. In this setup the pins on the lamp do no make contact in the lampholder.
Shunted vs NonShunted Lampholders — Blog from blog.1000bulbs.com
Why is it important to know what kind of sockets or tombstones are in your linear fluorescent or led light fixture? Good evening, i have a job coming up replacing multiple fluorescent lamps and ballasts etc with led one ended t8 lamps. Shunted tombstones (a socket or lampholder named after their shape) allow power between contacts and receive voltage with l/n on different sides.
Why Is It Important To Know What Kind Of Sockets Or Tombstones Are In Your Linear Fluorescent Or Led Light Fixture?
Current flows through an unshunted socket through multiple paths. The shunted sockets are generally used with rapid start ballasts. Non shunted or unshunted allows the wiring of one or two wires from each side of the socket as shown on the left side of the photo below.
I Have Just Had A Sudden Thought Whether Or Not The Previous Holders Are Likely To Be Shunted Or Not (I Should Have Checked Beforehand).
What is a non shunted lamp holder? In a word, we can get the conclusion : This unique construction allows direct connection with both.

T8 fixtures must have the input side sockets changed to t12 sockets of the non.
What Is Non Shunted Tombstone?
They allow separate points of entry for the wires with l/n on the same side. In contrast, thinklite led lamps are constructed to actively utilize both ends of the lamp, one end feeding the live connection and the other end feeding the neutral. If you have a t12 fixture, you are in luck, as you have all the necessary hardware already.
The Current Runs From The Ballast To The Tombstone Socket All The Way To The Lamp’s Pins.
If you have any inquiries for lamp holders, pls. What are non shunted lampholders? This provides a single track for the electrical current to travel from the ballast, through the tombstone, or socket, and to the lamp's pins.
