+All prices are extended estimates in USD.
+In general these are overestimates, so this should be an upper-estimate on cost.

+## Commerical LED emission spectra
+
+LED emission spectra were measured using an [Ocean Insight Flame VIS-NIR Minature Spectrometer](https://www.oceaninsight.com/products/spectrometers/general-purpose-spectrometer/flame-series/flame-vis-nir/) loaned by the [Goldsmith Group](https://goldsmith.chem.wisc.edu).

+## Ordering Blank LED stars
+
+The WPR lightsource is built to fit in industry standard, 20 mm [Indus Star A008 high power LED modules](https://leddynamics.com/indus-star-a007-a008).
+
+To order blank Indus Star A008 LED stars for custom LED star creation, contact [LEDsupply](https://www.ledsupply.com/contact-us), [LEDdynamics](https://leddynamics.com/contact-us) or other vendors.
+
+Other 20 mm 3-up LED stars in industry standard packages could be incorporated into the WPR, but have not been tested.
