In a T* ballast and T8 bulb more energy efficient then a T12 ballast and a T8 bulb? A:Depends on the CURRENT through the tube. When the Tube is run at 100% of rating, The T12 Takes more CURRENT to give a certain Brightness. Because the surface of the T8 is closer to the ion stream through the tube, it takes less CURRENT to light up the T8 to the same brightness. However, IF you use a T12 in a T8 ballast, you will get LESS CURRENT through the tube, and LESS POWER consumed ALONG with LESS Light.
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.
A 32 watt T8 bulb typically produces around 2850 lumens.
No, you cannot use a 4ft 4 lamps T8 ballast to run 4 18in T8 lamps. The ballast is specifically designed to match the length and number of lamps it was manufactured for. Using the wrong type of ballast can result in improper functioning or reduced lamp life.
A 32 watt T8 48 inch fluorescent bulb typically produces around 2800 lumens of light output.

A cover meter determines the distance from the outside face of the concrete to the depth of the reinforcement bar.

The weight of a 10mm steel reinforcement bar is approximately 0.616 kilograms per meter.
its the rear reinforcement bar under the rear bumper. its also known as a rear impact bar
In the context of concrete reinforcement steel, a Y12 bar refers to a deformed steel bar with a diameter of 12 millimeters. The "Y" indicates that it is a high-strength deformed steel bar. On the other hand, an R10 bar refers to a round steel bar with a diameter of 10 millimeters. The "R" signifies that it is a mild steel bar without any deformations.
