I wanted to DIY my own plant light, and proceeding to do some research about what they need (one of the sources being http://www.ledgrowlightshq.co.uk/chlorophyll-plant-pigments/).

I ended up finding a single LED meant for that purpose: the [LZC-00H100-0000 by OSRAM](https://www.digikey.com/product-detail/en/osram-sylvania-inc/LZC-00H100-0000/1537-1187-1-ND/6619069).

    I got the bad new yesterday that the LED is in End-of-Life on Digi-Key.

    Just FYI, the part number is LZC-00H100-0000, if you manage to source the part somewhere.
