if you like to invest think about this one. They have a new vuv led that is coming to market. It’s based on Graphene and is 10timez more efficient and 100 times less expensive than existing uv leds.
i wish I had invested in Cree whe. I had the chance. This will replace all fluorescent lights, cheap at source water sterilization, catalytic industrial processes never before possible. .... less expensive lithography
Anyway got got me excited as you can see.
