• Proven components and
technology
The Model 851 Plus utilizes a replaceable, helical strobe tube and an optically superior,
Fresnel, dome to maximize light output and completely fill the dome. These strobes are
multi-volt (12-48 VDC) and use 12-joule power supplies for brilliant warning signals. All
851 Plus DC models feature an “open-style” aluminum base with a flexible rubber
mounting gasket.
