# Photon Source LEDS

The WPP photon source consists of 3 high-power, single-color LEDs mounted onto an industry-standard 20 mm LED star package. 

WPP-compatible LED stars emitting narrow wavelength ranges across the UV-Visible spectrum are available from multiple vendors. A few are detailed below.

WPP-compatible custom LED stars mounted with 3.5 mm surface mount LEDs of any wavelength can be fabricated using a reflow oven. Please see [wpp-fabrication-operation.pdf](./fabrication-and-operation-instructions/wpp-fabrication-operation.tex) for fabrication instructions for more information.

All prices are in USD.
In general, prices are overestimates, thereby providing an upper estimate on cost.
