WTB: 219b 4000k Emitters and H17f Driver

Looking for Nichia 219b emitters in 4000k, preferably on a triple board but bare emitters at a good price are welcome.

Also looking for H17F drivers at good prices.

Might be interested in XPL-Hi 4000k emitters/triples, depending on price.

Can offer flashlights in trade!
