The LEDCube is a spectral tunable lighting product based on multi-channel LED technology, designed to create lighting environments with different space and luminance requirements, including lighting room and large test chart 45/0 illumination. Imatest offers a Thouslite LEDCube fixture, a set of two stands, to support 1, 2 or 3 LEDCube lights on each stand. The Thouslite LEDCube & Fixture Package combines everything you need to integrate the Thouslite LEDCube into your test lab.  LEDCube Data Sheet LEDCube User Manual

SKU: T-LEDCube-15 Categories: ,


● Reproduce high quality daylight illuminant with Color Rendering Index (CIE Ra) 99 and Metamerism Index (MI) Grade A

● Blackbody locus simulator to accurately produce a range of sources from tungsten to daylight varying Correlated Color Temperature (CCT) from 2000K to 20000K with tunable CIE Ra 0~100 and tunable Duv -0.02~+0.02. One device reproduces all light sources.

● SPD match to accurately reproduce any measured or imported SPD to record any light you want. It is easy to spread SPD files between different locations for light communication

● High light intensity output and luminance adjustable High power SMD LEDs, together with the software, guarantees high light intensity output, and the light intensity is dimmable while keeping the same light quality

● Fast change between illuminants and no warm up time Same illuminant properties during illuminant switch; no warm up time & instantly stable

● Single-channel control Arbitrarily control the intensity of each channel in LEDCube to design any light wanted

● Dynamic lighting Programmable light sequence and interval

● User-friendly software – LEDNavigator allow users to design light according to different optimization purposes. SDK available on request 

● Fast & accurate feedback – Maintain the same light quality, compensating for age and variable environments with external micro-spectrometer; more consistent than conventional lighting

● Flicker free based on AM driven method, it provides a flicker free lighting environment

● Longer life time and excellent long term stability compared to fluorescent technology, and optimized heat management resulting in excellent long term stability

● LED channel wavelength selection service from UV, VIS to NIR

● Wireless control – Up to 256 LEDCubes can be controlled separately or simultaneously via Zigbee wireless technology, easy to build  customized lighting space and future upgrade. Individual LEDCube control allows users to set different CCT for different LEDCubes in the same network to simulate actual environment
