The present invention replaces conventional lighting devices, such as incandescent lamps, fluorescent lamps, and LED lamps, with an integrated electro-luminescent film structure, subdivided into electrically isolated micro-panels. In different embodiments of the invention, traffic load is balanced across two or more IPSs, enabling enhanced availability during system failures, replacements or updates. A second programmable delay element coarsely adjusts the delay of a first signal associated with a dummy bitline. A base is connected to the bottom portion with a width which is greater than the outer circumference defined by the sidewall edge portion.
