A slim tubular lamp format with a nominal diameter of five eighths of an inch.
T means tubular and 5 represents five eighths of an inch in nominal diameter. Straight linear versions commonly use G5 bi-pin ends.
Offices, retail shelves, cabinet lighting, commercial coves, workshops and compact linear fixtures.
T5 tubes are available as fluorescent lamps and LED replacements in multiple lengths and outputs. Fluorescent T5 and T5 High Output systems use different electrical specifications.
Technologies represented in this library: LED, Fluorescent.
Available base types: G5.
| Technology | Common wattage range | Typical lumen range | Common colour temperatures | Common voltage options |
|---|---|---|---|---|
| LED | 4–30 W | 400–4000 lm | 2700K, 3000K, 3500K, 4000K, 5000K, 6500K | 120V; 220–240V; ballast-dependent options |
| FLUORESCENT | 4–80 W | 200–7000 lm | 2700K, 3000K, 3500K, 4000K, 5000K, 6500K | Ballast-operated |
These are representative market ranges, not guaranteed limits. Availability varies by manufacturer, voltage, base, beam, region and product generation.
Match length, G5 pins and original lamp designation, then determine whether the LED option is ballast-compatible, ballast-bypass or externally driven.
A tube that fits physically may not match the ballast or wiring. T5 and T8 tubes are different diameters and use different pin spacing.
Important: The library describes a lamp format, not a particular product. A shared shape does not guarantee matching voltage, base, dimensions, light distribution or control-gear requirements. Confirm the fixture label and product datasheet, or ask a Bulb World lighting specialist.
