Illuminate with Fluorescent Lights and Tubelights

Fluorescent lights are a popular lighting solution used in homes, schools, offices, warehouses, and commercial settings. Available in straight tube, circline, and U-bend formats, these tube lights are known for their energy efficiency, long life, and versatility across various applications.

All fluorescent tube lights work in the same way—by passing an electric current through a mercury-vapor gas that emits ultraviolet (UV) light. This UV light then excites a phosphor coating inside the tube, creating the visible light you see. To explore your options, visit our selection of linear fluorescent tubes, circline fluorescent tubes, and U-bend fluorescent tubes.

Linear Fluorescent Tubes

From T2 to T12, linear fluorescent lights come in various diameters and lengths to suit your specific needs. The most common is the T8 fluorescent light, which has a 1-inch diameter and uses 32 watts (marked as F32T8). Other sizes include:

• T5: 0.625-inch diameter
• T12: 1.5-inch diameter

These are ideal for high ceilings, under cabinets, retail spaces, and classrooms. If you're unsure which size you have, just measure the diameter and read the code printed on the lamp.

Circline Fluorescent Tubes

Compact and circular, circline fluorescent tubes are designed for small fixtures often found in kitchens, offices, or utility rooms. They range from 6" to 16" in diameter and are available in single and double tube options. Always check your fixture’s pin base type (2-pin or 4-pin) to ensure compatibility.

U-Bend Fluorescent Tubes

U-bend fluorescent tubes are a popular choice for 2x2 troffer fixtures and are used in office buildings, waiting rooms, and retail spaces. They offer the same functionality as linear tubes but in a compact shape, with standard leg spacings of 6 inches or 1.5 inches.

Shatter Resistant Fluorescent Tubes

For high-traffic or food prep areas, opt for shatter-resistant tubes, including T5, T8, and U-bend options. These have a special coating to contain glass shards if the tube is broken, ensuring added safety.

Appliance Fluorescent Tubes

Need compact or low-wattage bulbs? Appliance fluorescent tubes are ideal for vending machines, pinball machines, or food-service applications. For safe food use, choose NSF-rated models.

Fluorescent Tube Guards

Protect your lights and modify your ambiance with fluorescent tube guards. These sleeves protect from dust, moisture, and breakage while offering color filters or UV-blocking features for specialty settings like photo labs and clean rooms.

How to Dispose of Fluorescent Tubes

Fluorescent lights contain small amounts of mercury and must be disposed of properly. Never toss them in the trash. Instead, recycle your tubes at local drop-off centers or use linear fluorescent recycling kits to ship them to certified recyclers.

FAQs: Fluorescent & Tube Lights

How does a tubelight work?

A tubelight (fluorescent tube) works by sending an electric current through a mercury-vapor gas, which emits UV light. This UV light hits a phosphor coating inside the tube, producing visible light.

How much electricity does a tubelight use?

It depends on the wattage. Common T8 tubes use around 32 watts, while T5 tubes range from 14W to 54W depending on length and output. Pairing tubes with occupancy sensors or programmed start ballasts can help improve energy savings.

Are T4 and T5 bulbs interchangeable?

No. While they may appear similar, T4 and T5 bulbs have different diameters and pin spacings, making them incompatible with one another’s fixtures.
