What is the difference between a T5, T8, T10, and T12 tube?

Tube diameter explanation

You replace a T5 with a T5. But what does it all mean? What does T5 represent? The “T” stands for Tubular. The number that follows “T”, in this case being 5, represents the diameter of the tube. The diameter is measured in 1/8 of an inch. A T8 tube is 8/8 in diameter which is 1 inch. HomElectrical offers T5, T8, T10, and T12 tubes.
T2 = 2/8 = ¼ inch
T5 = 5/8 inch
T8 = 8/8 = 1 inch
T12 = 12/8 = 1 1/2 inch

What is color temperature?

Color temperature info-graph

LED bulbs do not produce heat, therefore when we are talking about color temperature we are not talking about the actual temperature of the bulb, but instead the color that is being produced. The temperature is measured in Kelvin’s and represents the atmosphere you are trying to set. LED lights that fall between the temperatures 2700K and 3000K are your warmer/softer white lights. Perfect for hospitality environments. LED lights between 3500K – 4100K work well for kitchen and bathroom areas with its white color illumination. LED lights with a temperature between 5000K – 6500K are best for commercial and industrial application because the light produced is closer to natural daylight.
