The Edwards 91B Series AdaptaBeacon heavy duty portable strobe lights are designed to maximize the strobe tube brilliance. This is accomplished with a series of complementing fresnels that cause the dome to "fill" with light each time the strobe flashes. This design feature increases the AdaptaBeacon "on-time", thus improving viewer perception. Beam distance is also increased with external fresnel lenses. The 91B Series' trigger and timing circuits are included as integral parts of the power supply. Replacement costs are reduced as it is necessary to replace only the strobe tube.
The 91B Series heavy duty portable strobes are ideal for use in identifying repair areas, temporary barriers, or emergency construction areas.
