KRAFT LED
KRAFT LED is an integrated lighting system for suspended ceilings. The fitting is not cut into the ceiling — it replaces a part of it: a T‑bar, a baffle or an open cell profile. One set of 29 W and 3217 lm at 4700 K covers 8–10 m² (200 lx) in a room 3.5 m high.
Three mountings: T‑LED, G‑LED and InterioLED (coming soon)
The fitting is the same in all three. The only difference is how it attaches. You choose the fixing to suit the ceiling, not the output — flux, colour temperature and power draw are identical across T‑LED, G‑LED and InterioLED.
T‑LED
Replaces a standard T‑bar in the grid. KRAFT Fortis profiles, 15 and 24 mm wide, carry the load. It goes in as the ceiling goes up — no extra fixings needed.
- Width: 15 mm with a flat diffuser · 24 mm with a curved one
- Length: 600 or 1200 mm
G‑LED
Fixes with heavy-duty double-sided tape straight onto a baffle or an open cell profile. The most flexible option — it will go onto almost any suspended structure.
- Width: 15 mm with a flat diffuser · 24 mm with a curved one
- Length: 600 or 1200 mm
InterioLED
A complete fitting built on a KRAFT Cube baffle, 35×65 or 35×105 mm, with the driver hidden inside the profile. It fixes straight to the slab, on hangers or on its own cables — even where there is no suspended ceiling at all.
- Width: 24 mm, curved diffuser
- Length: 1200 or 2400 mm
- Power: 29 W at 1200 mm · 58 W at 2400 mm
| Fixings | Width | Length | Set | Covers | Separate hangers |
|---|---|---|---|---|---|
| T‑LED — replaces a T‑bar | 15/24 mm | 600/1200 mm | 2×600 or 1×1200 — 29 W | 8–10 m² (200 lx) | none |
| G‑LED — double-sided tape | 15/24 mm | 600/1200 mm | 2×600 or 1×1200 — 29 W | 8–10 m² (200 lx) | none |
| InterioLED — built on a KRAFT Cube baffle | 24 mm | 1200/2400 mm | 1×1200 — 29 W · 1×2400 — 58 W | 8–10 m² (200 lx) · 16–20 m² | optional |
About the sizes. The catalogue lists nominal lengths — 600, 1200 and 2400 mm. The actual module length is 595 mm. If you are planning a continuous baffle-and-luminaire run, ask for the actual dimensions before ordering the cutting list.
How the code reads: T24 29W 4700K — 1200. First the fixing, then the width, the wattage, the colour temperature and the length.

Most recessed fittings are tied to one ceiling: open cell gets downlights sized to the cell, a T‑bar grid gets 600×600 panels. KRAFT LED breaks that link. Pick the ceiling first, the fixing second.
T‑LED becomes part of the suspension system, replacing a standard 600 or 1200 mm T-profile. G‑LED fixes to the T-profile with double-sided tape. InterioLED hangs separately on its own cables.
G‑LED mounts on the carrier; InterioLED builds into the cube profile with the driver inside.
Ceiling pageG‑LED fixes to the carrier and the blade spacing stays as it is. InterioLED hangs separately on its own wires.
Ceiling pageG‑LED sits in the grid, and the cell size does not dictate the model. InterioLED hangs separately on its own wires.
Ceiling pageSame as the classic type: G‑LED in the grid, InterioLED separately on its own wires.

How many sets a room needs
One KRAFT LED set covers 8–10 m² (200 lx) in a room 3.5 m high and up to 20 m² in area. In bigger rooms it stretches to 10–12 m². The exact number depends on the required level: under EN 12464‑1 an office 500 lx, a sales area 300 lx, a hotel reception 300 lx.

Where the numbers come from
The 3217 lm figure comes from the KRAFT LED 29 W datasheet, backed by the .ies photometric file.
Illuminance levels follow the applicable lighting standards.
The utilisation factor is calibrated against the published figure of 8–10 m² (200 lx) per set at 3.5 m ceiling height, and 10–12 m² for rooms over 20 m².
Annual consumption: 10 h a day × 250 days.

Seven-point comparisonInstalling KRAFT LED
Installation starts with the calculation, not the fitting. Dialux gives you the quantity and the positions, the ceiling gets set out, and only then do the fittings go in. With T‑LED the order matters more than usual: it replaces a T‑bar, so it has to be in the ceiling take-off from the start.
- 01Set the fitting positions out on the drawing BEFORE the grid goes up.
- 02Fit KRAFT T‑LED at 600 or 1200 mm in place of the ordinary T‑bar where the drawing says.
- 03Wire back to the driver, watching the polarity.

Frequently asked questions
An office of 60 m² at 500 lx under EN 12464‑1 needs about 19 KRAFT LED kits — roughly 3.2 m² per kit. The exact number depends on ceiling height and surface reflectance. Use the calculator above or order a free Dialux calculation.
