 # Lightsource LEDS
 
-The WPR lightsource is built around 3 high-power, monochromatic LEDs mounted onto an industry-standard 20 mm LED star. 
+The WPR light source is built around 3 high-power, monochromatic LEDs mounted onto an industry-standard 20 mm LED star package. 
 
-Compatible LED stars are commercially availible in discrete wavelength ranges across the UV-Visible spectrum.
+WPR-comptabile LED stars emitting narrow wavelength ranges across the UV-Visible spectrum are  available from multiple vendors. A few are detailed below.
 
-Custom LED stars mounted with 3.5 mm surface mount LEDs of any wavelength can be fabricated using a reflow oven.

 ## 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).
