T8 LED Tube Bulbs for G13 Raster Fixtures

Do filter

T8 LED Tube Bulbs provide a safe and extremely energy-efficient Retrofit modernization for existing raster fixtures in offices and industrial premises.

Traditional daylight or fluorescent lamps are distinguished by high electricity consumption, harmful mercury content, and regular stroboscopic flickering, which causes pronounced visual fatigue in the working environment. The VIDEX T8 LED series tubes (available in 600 mm, 1200 mm, and 1500 mm lengths) are an exact G13 base replacement, created for a quick modernization of room lighting while preserving the old luminaire housings. By disconnecting the old starters and chokes from the circuit and establishing a one-sided or two-sided connection according to the instructions, LED tubes provide significant power savings and an immediate 100% lumen output without a warm-up phase. Using a high-quality SMD diode matrix and a glass or nano-plastic bulb with a frosted diffuser, they project a uniform light beam in a 330-degree radius. The internal driver maintains non-flickering (No Flicker) operation and protects against network voltage surges (185-265V), guaranteeing a service life of up to 30,000 hours.

Design parameters and mounting advantages:

Standard G13 base: Corresponds exactly to the classic sockets in raster luminaires, making tube replacement fast and engineeringly simple without additional reconstruction.
Excellent light transmission: The frosted glass or polycarbonate shell not only protects the internal board but also diffuses harsh light, reducing glare on computer screens.
No UV radiation: Unlike old fluorescent bulbs, LED technology does not emit the ultraviolet spectrum and does not contain environmentally hazardous gases, facilitating disposal.
Effective cooling: The internal architecture without the use of glue allows the diodes to dissipate heat quickly, preventing overheating and lumen drop under continuous load conditions.

By replacing the tubes in warehouses or corridors, not only electrical safety improves, but also the overall uniformity of lighting throughout the infrastructure. For convenient management of room lighting mains after replacing light elements, it is recommended to integrate quality mounting components, such as white surface-mounted switches and sockets.

Q: What is the engineering reason for transitioning from legacy fluorescent (FL) tubes to architectural T8 LED tube bulbs?

A: T8 LED bulbs provide a luminous efficacy exceeding 100 lm/W, consuming half the energy (e.g., an 18W LED fully replaces an old 36W gas-discharge tube). LED technology strictly eliminates light flickering (stroboscopic effect), which creates optical illusions of moving machinery in manufacturing. Furthermore, they contain no mercury and do not release toxic gases if broken.

Q: How to properly connect a single-end powered T8 LED tube in legacy G13 luminaires?

A: In single-end powered T8 LED bulbs, the AC 230V phase (L) and neutral (N) are connected to only one specifically marked end of the bulb. When retrofitting older fixtures, the legacy electromagnetic ballast and starter must be disconnected and bypassed, supplying mains voltage directly to the designated G13 socket. This prevents short circuits and increases efficiency.

Q: How does using a polycarbonate (PC) body or lens affect the operational safety of a T8 LED bulb?

A: Unlike fragile glass gas-discharge tubes, VIDEX T8 LED bulbs made of nanoplastics or wrapped in thermoplastic film are mechanically shatterproof. Even if dropped from the ceiling during mounting, the tube does not break into hazardous sharp shards. This IK impact resistance is a critical European safety (HACCP) standard in food processing halls, warehouses, and gymnasiums.

Q: How does the presence of an internal aluminum heat sink profile extend the lifespan of a T8 LED bulb?

A: During prolonged use of 1200 mm or 1500 mm long bulbs in offices and manufacturing, heat accumulates on the linear LED board, which the aluminum beam absorbs and dissipates along the tube length. This thermal management ensures low crystal operating temperatures (below +65°C), guaranteeing stable light output within the L70B50 standard for over 25,000 hours without degradation.

Q: Why are 4000K or 6500K color temperatures primarily selected for industrial spaces and offices?

A: The 4000K (neutral white) and 6500K (cool daylight) spectra provide the highest contrast resolution and precise detail visibility when working with documents or fine mechanisms. Cool spectra biologically suppress drowsiness and boost employee concentration according to EN 12464-1 workplace lighting standards, whereas 3000K promotes eye fatigue.
