3.9Stroboscopic Flashing Light

The SM-2 Flashing Light uses a capacitor discharge xenon flashtube and meets the following requirements:

A.A completely sealed solid state circuit converts power from the battery and supplies it to the flashtube.

B.A suitable capacitor discharge xenon flashtube is provided which is compatible with the electronic flashing circuit and lens to provide the required light output. The service life of this flashtube is rated for over 1,000,000 flashes.

C.The light will flash at a rate of 60 ± 1 flashes per minute with a minimum intensity of 2 cd for a minimum of 15 hours. Light from each flash is radiated in all directions of upper hemisphere.

3.10Battery Connection

All operating voltages are furnished by an integral battery pack. Operating voltage is 6.0 VDC. (Shipped without battery from factory)

Electrical connections between the main circuit board and the associated battery are accomplished by the use of clearly marked terminals and color-coded lead wires.

3.11Buoyancy

The SM-2 is independently buoyant.

A matter of balance

Marker lights need to float upright for maximum visibility. The 6 volt lantern batteries provide the ballast for these lights. Although these batteries are the same size, their different chemistries cause them to have varying weights. It is imperative that only the 6 volt battery models suggested are used. Too little ballast and the light will lie over on its side and be ineffective; too much weight and the light could sink. If you have any doubts that you are using a battery of appropriate weight, test the light by placing it into shallow water. The results will be obvious; if the light floats upright, it's good. If the light sinks, the battery is too heavy.
