You can buy the LED direct from Nichia. I have no present plans for the ones I have mounted on the E-screws. These are mounted on a real nice custom PCB that Wayne designed that has numerous silver filled vias transfering the heat from the top copper plane to the bottom copper plane with a gap separating the planes of about .007".
This isn't B/S/T and I don't want to appear to be soliciting a sale here. :nana: If you are interested in one of mine, please send me an e-mail.
