Kaiser RB 40D LED Lighting Unit

Kaiser RB 40D LED Lighting Unit | Soft, even light for copy work

Flat originals and copy subjects receive soft, balanced illumination from the Kaiser RB 40D LED Lighting Unit. Its two 40W softlights each use 200 LEDs, with a 5600K daylight colour temperature and CRI 95 for neutral, accurate colour. That combination is especially useful when colour fidelity matters, such as when reproducing artwork or photographing documents on a copy stand. The two heads can be raised or tilted, so you can position their light around the subject rather than relying on one fixed direction. Diffuser panels soften the output across the illuminated area, helping reduce harshness on flat subjects. The lights are dimmable and flicker-free, and emit no infrared or ultraviolet radiation. That makes the RB 40D a considered lighting setup for studios, archives and other workspaces where repeatable copy lighting matters. Its adjustable arms and marked positions support consistent setups from one session to the next, while built-in cable holders keep the leads routed neatly. The set is made to work with Kaiser’s R1 System, RSD and RSDmot copy stands, tying its positioning features to a specific copy-work setup.

Why it is useful

• 28 × 20 cm diffuser panels: Each panel spreads the light over a broad area and softens it for more even illumination across a flat subject.
• Height- and tilt-adjustable heads: Set the lights to suit the position of the original and the copy stand, rather than being restricted to a fixed angle.
• Cast-aluminium clamps: The vertical arms use sturdy clamps to hold the light positions during setup and adjustment.
• Locking hinges and height markings: Secure the arm position and use the markings to return to repeatable settings for ongoing copy work.
• Dimmed, flicker-free output: Adjust brightness to suit the subject and working conditions, with flicker-free operation for steady illumination.
• No infrared or ultraviolet radiation: The lights emit neither IR nor UV, a useful detail when lighting originals that need careful handling.
• Copy-stand fit and adjustable guides: Compatible with Kaiser R1 System, RSD (K5602) and RSDmot (K5603) stands; the angle guides adjust for baseboards 50–60 cm deep.
