Lampu Linear LED Tiub Bulat untuk Pencahayaan Pejabat

The ILED-LL-C T60 is a round tube LED linear light designed for pendant and suspended ceiling installations where bidirectional light output enhances both task and ambient illumination. Its φ60 mm cylindrical body emits light upward and downward through a frosted polycarbonate diffuser, creating a soft, shadow-free wash that works equally well as functional office lighting and a visible design element. The T60 belongs to the broader LL-A family; unlike the flat LL-A-1 recessed model or the wider LL-A 75 mm and 90 mm surface-mount variants, the T60 offers a compact circular profile suited to corridors, feature walls, retail display runs and open-plan workspaces.

330° bidirectional light distribution

The T60’s round tube design radiates light in three dimensions — upward, downward and around the full circumference — creating a soft, shadow-free wash of illumination. The upward component bounces off ceilings to increase overall room brightness and reduce contrast ratios, while the downward component provides direct task lighting for work surfaces below. This dual-output approach means fewer fixtures are needed compared to downward-only linear luminaires, particularly in spaces with light-colored or reflective ceiling finishes.

The frosted polycarbonate diffuser wraps the LED array around the tube’s full perimeter, eliminating visible hot spots and producing a visually uniform glow from every viewing angle. When arranged in parallel rows or perpendicular ceiling grids, the T60 creates continuous lines of light that function as both luminaires and architectural accent features.

Sizing and layout flexibility

The T60 is offered in three standard lengths — 1000 mm, 1500 mm and 2000 mm — each scaled to its wattage range. The 1000 mm variant (10–20W) suits narrow corridors and small display runs. The 1500 mm (15–35W) and 2000 mm (20–40W) variants cover larger office bays and retail fronts. Bespoke lengths can be ordered for non-standard ceiling layouts, with minimum order quantities applying to custom orders.

Because the T60 mounts by cable suspension, spacing between fixtures is independent of tube length — unlike surface-mounted battens where spacing is constrained by housing size. This gives designers flexibility for both dense grid arrangements and sparse feature installations where the circular light tube is intended to be seen as a design element rather than hidden in the ceiling plane.

Typical applications

The ILED-LL-C T60 is suited to commercial interiors where even, glare-free illumination is essential. Corridors and circulation spaces benefit from the tube’s narrow φ60 mm profile, which provides a continuous line of light without visual clutter. Open-plan offices use the T60 in pendant grids to create visual zones over workstations while maintaining an open ceiling aesthetic. Retail environments hang the tubes above display runs and checkout areas, where the bidirectional output reduces shadows on products. Showrooms and reception areas exploit the fixture’s sculptural quality — the glowing ring becomes a visual anchor in an otherwise plain ceiling.

Why do buyers pick the ILED-LL-C T60 over other linear lighting options? Here is what we hear from customers:

330° light output — light goes up and down. Unlike flat panel linear lights that direct illumination only downward, the T60’s round tube shape sends light in all directions. For pendant installations, the upward glow adds ambient fill while the downward beam provides task lighting — two functions in one fixture.

φ60 mm compact diameter — low visual presence. The narrow circular profile fits into tight spans and tight visual compositions. Multiple T60 units can be spaced closely along a corridor or feature wall without creating visual clutter, something harder to achieve with wider flat-profile alternatives.

White, CCT, RGB, RGBW and RGB+CCT — one housing, many moods. The same φ60 mm housing is offered across five color families. Project specifications can mix white and color variants along a single run, using DALI for white/CCT zones and DMX/SPI for color accents, all from the same physical form factor.

Plafon pejabat dan ruang perkongsian kerja. — Pendant-hung T60 tubes define work zones and guide circulation paths. Tunable CCT versions shift from cool daylight for focused tasks to warm white in the evening, supporting circadian rhythm in open-plan offices.

Kedai runcit dan bilik pameran. — Continuous linear runs of T60 tubes create a rhythmic visual line that draws customers through the space. RGBW variants add dynamic color accents to promotional displays, while the >90 CRI option renders merchandise colors accurately under white light.

Hotel dan koridor perhotelan. — Round tube pendants add architectural character to hotel corridors and lobby areas. Tunable CCT creates different atmospheres — warm white for evening check-in, cooler daylight for morning — while the 330° output fills the corridor with soft ambient light.

Institusi pendidikan dan perpustakaan. — Uniform 120° beam distribution from the frosted PC diffuser eliminates shadows on desks and reading tables. DALI control supports scheduling and daylight harvesting in classrooms and study areas with predictable occupancy patterns.

Dalaman kediaman dan siling ciri. — Homeowners specify the T60 for kitchen island pendants, living room feature lines and bedroom ambient strips. The RGB+CCT option serves both task lighting (bright white) and mood lighting (warm color) from the same fixture.

Pengesahan gaya pemasangan. — The T60 is designed for pendant or suspended ceiling installation. Confirm your hanging method — cable, rod or chain — and ensure adequate ceiling height. Recessed mounting is not supported.

Padanan protokol kawalan. — DALI or 0-10V for single white and tunable CCT variants. DMX512 or SPI for RGB, RGBW and RGB+CCT variants. Confirm your control system at order — the driver is factory-fixed and cannot be upgraded later.

Length vs wattage selection. — The 1000 mm variant covers 10–20W, the 1500 mm covers 15–35W and the 2000 mm covers 20–40W. Match the length to your lumen requirement — a 1000 mm unit at 20W will not match the output of a 2000 mm unit at 40W.

T60 vs LL-A-1 recessed linear. — The T60 is a round tube pendant light (φ60 mm diameter, 330° output); the LL-A-1 is a flat recessed linear (35 mm height, downward-only output). Choose the T60 when the fixture is a visible design element; choose the LL-A-1 for a flush ceiling finish.
