August 30, 2021
June 9, 2022


This package combines everything you need to integrate the Thouslite Tunable LEDCube lights and adjustable stands into your test lab:

  • LEDCube spectrally tunable lights. Select quantity of 2, 4 or 6 lights total (1, 2 or 3 lights per side), or 1 if not using the stand. Lead time 3-4 weeks.
  • Controller. Set quantity to 1 Controller for every two LEDCube lights.
  • Thouslite Navigator software
  • The Imatest LEDCube Fixture (set of two) which can accommodate 1, 2 or 3 LEDCube lights per side. Lead time approx. 14 weeks.
  • Your choice of the Jeti Spectrometer scb 1211UV-2 or the Konica Minolta CL-500A Illuminance Spectrophotometer

The Thouslite LEDCube is a highly tunable, reflective light source. Reproduce any phase of daylight with the highest quality Color Rendering Index (CRI: 99) and Metamerism Index (MI: Grade A). Simulate various lighting environments to evaluate the performance of your camera or sensors, including tests for auto white balance, color rendering, auto exposure, etc.

Thouslite LEDCube-15 Features

Thouslite Spectral Tuning Comparison

● 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

Adjustable Stands – Place up to 3 LEDCubes on each fixture using shelves with adjustable heights. Position the fixtures in any orientation with lockable casters
