Find out more about Color Temperature
Although lights may appear white, they actually range from warm to cool tones. Since different color tones are appropriate for different settings, it's important to use a bulb with the right color temperature for you. Color temperature describes the "whiteness" of a light source, and is measured in Kelvin (K). A higher Kelvin temperature is a bluer, cooler light while a lower Kelvin temperature is warmer, with a yellow/red appearance. Warm tones are perfect for comfortable settings, while cooler tones are ideal for professional environments.

How to Measure Light Bulbs
Not only do bulbs have many different shapes, there are also varying sizes. The size of a bulb is measured in eighths of an inch at the widest point of the bulb - or the diameter. A bulb's code is created by using a letter followed by the measurement.
For Example:
"A19" indicates a standard bulb having a diameter of 19/8 inches.
"T10" indicates a tubular bulb having a diameter of 10/8 inches.
"MR16" indicates a mini reflector having a diameter of 16/8 inches.
"ED37" indicates a large HID bulb having a diameter of 37/8 inches.

Measuring Fluorescent Lamps
To determine the length of a fluorescent lamp, you do not measure the bulb. The nominal length of the bulb is the measurement from the back of the socket to the fixture.
To find the type of lamp needed, measure the endcap and use this illustration as a guide.
