The Single Magnum Smart Strobe can be powered either by an AC lighting coil or by a battery. It flashes in a double wink pattern at a rate of 74 per min. The Double Dual Magnum is DC powered only and fires a double flash on one head then the other in an alternating pattern. The first flash catches the eye and the second identifies your position. The Double Magnum Smart Strobe is the same as the Double Dual Magnum except that it will operate on lighting coil or battery. All drivers measure 4-1/2" x 3-1/2" x 1-5/8" and weigh 10.5 oz. Replacement bulbs come with bulb & trigger mounted to a printed circuit base that must be soldered to three wires. Note: All strobes are 25 Joules
