An apparatus for testing light emitting diodes comprising a chamber which is configured to heat or cool LEDs inside the chamber by ambient heating or cooling of the LEDs and an optical sensing unit configured to sense light emitted by the LEDs while the LEDs are inside the chamber. The torch consumable components, in part, comprise an electrode and a tip that include a variety of configurations for improved cooling, electrical contact, and attachment to adjacent torch components. The system is designed to divert polluted rooftop runoff, capture clean rooftop runoff and store this clean water for irrigation purposes and nonpotable uses, while infiltrating excess water to recharge groundwater supplies thereby replicating the natural hydrologic cycle. The apparatus comprises at least an arithmetic section for carrying out the arithmetic step, and a memory for storing the movement time management table. Next to the p-base region, an n+-source region is formed.
