Visual humans of earth, I give you our new external power supply concept:
While our prototype sample won't look exactly like this, it will look similar. This power supply enclosure measures 122mm wide (4.8") and 36mm high (1.4"). It can be extruded to any length, but this one is designed to hold a single power supply for 2 circuit boards. We will have longer models that hold 2 and 3 power supplies respectively (for 160W and 240W models).
As promised we have two power jacks on this device. One is for 110V input, and the other can be used with a special connecting cord that has a female end on both sides for daisy-chaining. In the center of the power jacks is a dimmer knob. On the opposite end of the power supply will be the output cord to the LEDs. If you can think of any other features or elements to add to this power supply, speak up now or forever hold your peace!
To service the power supply, the two upper screws on each end cap would be removed. The upper casing then lifts off, giving clear access to the power supply contained within. I haven't heard back yet if we can do dimming on this model, but hopefully will soon. The prototypes will not be dimmable.
