    Recommended Under Cabinet LED with high CRI and R9 values

    If you want the best CRI, what i have found is : https://store.yujiintl.com/collections/vtc-d50-series https://store.yujiintl.com/collections/vtc-series they are violet pumped LEDs so they have a broader possible emission range than blue pumped ones. Not cheap though.

    Cu ground bar heatsink

Previous to this build, i...

    LED brightness vs cooling results (regarding Nichia LEDs) questions

    I've heard there can be issues with peltier cooling if not addressed correctly - when you power off the unit, heat will flow back into the cold side - potentially enough to damage sensitive components. I've been amazed at the thermal management of a copper bus bar and CPU coolers -...

    Narrow Optics how narrow are they?

    Cu ground bar heatsink

    Hey guys, I apologize, next time i start a build thread, I'll make sure i have everything or am done building. 24V PSU and reflectors are backordered, waiting on a reply back from supplier as to when they'll be available. I decided to go with low voltage DC/DC drivers, as opposed to the way...
