Fluorescent Light Dimensions

All fluorescent lamps use the same technology but there are several different variations and sizes.

Fluorescent light dimensions.

Lamps are typically identified by a code such as fxxty where f is for fluorescent the first number xx indicates either the power in watts or length in inches the t indicates that the shape of the bulb is tubular and the last number y is the diameter in eighths of an inch sometimes in millimeters rounded up to the nearest millimeter. Tube lights also known as linear light bulbs are frequently used in office buildings kitchens work spaces and commercial installations as well as homes with varying sizes and brightness levels this guide reviews the different types and configurations of tube lights both fluorescent and led so you can choose the best tube lights for your light fixtures and other lighting needs. An electric current in the gas excites mercury vapor which produces short wave ultraviolet light that then causes a phosphor coating on the inside of the lamp to glow a fluorescent lamp converts electrical energy into useful light much more efficiently. Sizes range from t2 to t17.

Connects to a medium bi pin g13 base. Fluorescent tube lighting comes in a range of sizes. A fluorescent lamp or fluorescent tube is a low pressure mercury vapor gas discharge lamp that uses fluorescence to produce visible light. Above the 4 pin connector segment of a t9 circular fluorescent 32 watt.

T8 fluorescent bulb 32 watt pin spacing 13mm sold in a wide range of color temperature and light output in lumens straight or u shaped. 1 888 455 2800 fax 1 508 363 2900. The diameter of the tube is described in eighths of an inch as it is for incandescent lamps so a fluorescent lamp 1 inch in diameter eight eighths is a t8. Fluorescent lamps are identified by a standardized code that reveals valuable information about operating characteristics and physical dimensions.

There are three common sizes shown in the chart the below. Linear fluorescent tubes are the most common type of fluorescent lamps.

Determining the tube size of the fluorescent light will help you decide which tube lighting is a suitable replacement. The difference is in the diameter. T12s are 1 5 inch diameter.
