SugarCUBE Illumination Systems

Unsurpassed Light Intensity with LED Efficiency

The SugarCUBE line of LED fiber optic illuminators provides the highest intensity light for a variety of laboratory and technical needs. Each member of the CUBE family couples an exceptionally bright LED with Nathaniel Group’s powerful electronic driver circuitry for maximum light output. The life of each LED light source is equivalent to approximately 300 tungsten halogen bulbs, allowing users to cut downtime and save thousands of dollars on bulb replacement.

The SugarCUBE line - a model for every application

SugarCUBE Standard - A high intensity LED fiber optic illuminator available in white, red (624nm), blue (463nm), and green (523nm).

SugarCUBE Ultra - For the most demanding applications, the SugarCUBE Ultra is the most powerful LED light engine available. It replaces the previous SugarCUBE Quad White model. The output is 764% greater than the previous top of the line Quad when using a 3mm LLG. Please see the datasheet for specifics.

MicroCUBE - The MicroCUBE improves upon our SugarCUBE Ultra model for light guides larger than 8mm diameter. We have incorporated a pulse capability down to 10 microseconds with fast rise and fall times as well as a rear panel switch to select rising or falling edge triggers. The MicroCUBE delivers industry leading flicker free light output and offers an expected LED lifetime of up to 40,000 hours. This new model offers significant reductions in both cost and size.

SugarCUBE LITE - For low-cost, high-lumen output, the SugarCUBE LITE offers superior technology in a cost-effective form factor. Its consumer-friendly pricing makes it ideal for many research and industrial uses. The LITE is available in bright white and can only be ordered from our website.

SugarCUBE Multi-wavelength solutions
- We can connect multiple SugarCUBEs together to create a switchable multi-wavelength system with a high output.
