CIRCUITRON 800-1031, FLW-1, Strobe Flasher-White, NEW From Circuitron:The CIRCUITRON FLW series strobes provide a bright white flash from a small incandescent lamp (included). These units may be powered from batteries or by using one of our TP-2 or TP-3 Track Power Adapters. The lamps are prewired and only two wires need to be connected to the power source. All the White Strobes require 2.8—3.0 volts. Due to the fragile nature of the sub-miniature incandescent lamps, you must be careful to never apply voltage exceeding the unit’s rating or destruction of the lamp may occur.
