The Phos-4 LED light source from In Tandem Designs Pty Ltd. is a temperature-clamped, fiber-coupled device intended for fluorescence and transmission measurements, as a precision light source for production and test, and as a controllable light source for general illumination.

The Phos-4 features a range of user-interchangeable LED modules with wavelengths from 280 to 740 nm. The Phos-4 can independently control up to four individual dies of a multiwavelength LED, allowing users to combine wavelengths to perform functions such as differential fluorescence measurement or to provide balanced white light sources. A precision reference controls the linear current drive capable of <1 μs switching at 800 mA. The LED current can be programmed in 0.4-mA steps from 0 to 800 mA and in continuous, PWM, or sequencer modes.

The precision drive and thermal clamping combine to make a highly precise optical source with power stability as low as 0.02%/hour.
