Sandhouse Design (Ocean Optics) Light Source for Spectrophotometers.  Power sources are not shown, but are included.
Three units in this package, with a total of seven LED light sources.  The Multi Channel currently has 490, 470, 455, and 405 installed.  The Single Channels are VIS and 470.  The 490 in the MCLS does not seem to work, though, there is a spare 490 included.  I'm Do Not know if the spare works, so bid appropriately.  These are available through OO at roughly 0ea, making the BIN price a super deal.
The Sandhouse Design multi-channel LED Light sources are designed to power 4 of Sandhouse Design's LEDmodules. The constant current drivers can each drive up to 2amps continuously or 4 amps at 50% duty cycle.The user changeable LED modules are automatically recognized and the drive current is adjusted accordingly.The light source can work alone or be controlled through its' USB interface.
