The invention relates to a lighting apparatus for coupling to an LED driver. The lighting apparatus comprises a plurality of LEDs in a series connection arranged to form an LED string having a first end and a second end, a heatsink thermally coupled to the LED string, wherein the heatsink is electrically conductive, a capacitor coupled between the first end of the LED string and the heatsink and an electrical connection between the second end of the LED string and the heatsink.

Apparatus, methods and systems are disclosed related to negotiation mechanism among control devices () each having a dedicated hierarchy level configured to obtain DC current from the control network () with at least a power source (′) on the network (). The control device () with a higher dedicated hierarchy level may request another control device () with a lower dedicated hierarchy level to release current for its use, when the available current at the power source (′) is not sufficient.
