The present invention provides an active double metal cyanide catalyst made of a non-hexanitrometallate containing double metal cyanide compound, one or more unsaturated tertiary alcohols and about 0 to about 80 wt. The system includes a cluster that includes a plurality of intermediary devices and an SNMP agent executing on a first intermediary device of the plurality of intermediary devices. The buttons are mounted on respective slide members mounted in the housing spring biased apart so that the buttons can be depressed. A pressure valve is provided for injecting pressurized air into the interior of the shell and through way valves are provided for the nose and tail to allow the nose and tail parts to maintain the same pressure as the main body. When any of these LED circuits has failed, an output light power of white LEDs of LED circuits that have not failed is increased by a light power control section, thereby compensating an extinguished amount of the failed LED circuit.
