Yes, these lamps can be interchanged.
T12 lamps (tubes) are still available until the end of 2010 when the manufacturers can only sell off any inventories left on hand. It is now illegal though to buy new fixtures with T12 lamps in them. Actually you can buy fixtures with T-12 bulbs. The fixtures now come with Electronic T12 Ballast. Only Magnetic ballast for 4' and 8' were affected by e-pact. Now some big box stores may only sell T8 fixtures but that has to do more with price point.
T12 lamp ordinarily known as fluorescent lamp or fluorescent tube refers to a gas-discharge lamp that uses electricity to excite vapor. T12 lamp is available in different colors such as light blue, violet, green and red.
The three types of hot-cathode fluorescent lamps are T12, T8, and T5. T12 lamps are the oldest and largest, T8 lamps are more energy-efficient and commonly used in commercial applications, and T5 lamps are the smallest and most efficient, often used in task lighting or compact installations.
Depends on the ballast most of the newer electronic ones work on a wide range of lamps and input voltages and one or two lamps
Yes you can.
Absolutely. Only you need connect together two wires coming from each lamp holder (shunt).
Fluorescent tubes are measured in 1/8ths of an inch. A T8 would be 8/8ths or one inch. Likewise a T12 would be 12/8ths or one and a half inches.
The only difference between Y12 and T12 is the Kilos per meter. In a Y12 there is 0.888 Kilos and a T12 bar has 0.612 Kilos.
Yes a T12 lamp socket will take a T8 tube. The T8 tube will not operate. The T8 ballast is an electronic ballast where as the T12 ballast is a magnetic type. If you are changing over fluorescent fixtures to the smaller T8 lamps then the ballast has to be changed and the end sockets have to be rewired. The schematic on how to do the rewire is on the electronic ballast's label.
