The TriLite MS1 is a 110 VAC strobe warning light for indoor and outdoor signaling. Two models cover the mounting choice: the MS1-110SP is the permanent mount and the MS1-110SM is the magnetic mount.
Output is 3 to 4 watts at 3.6 joules, firing 70 to 80 times a minute through a 360 degree Fresnel lens. Current draw stays under 0.04 amps at 115 VAC. The unit measures 6.5 inches high and 5.5 inches across.
Dome colors are amber, blue, clear and red. If your equipment runs on battery power instead of mains, the MS11 is the DC member of the same compact strobe family.

What is the TriLite MS1 AC strobe warning light?

The MS1 is a compact high-output strobe for signaling, safety and warning work on 110 volt AC power. It fires a short, bright burst rather than a steady flash or a rotating sweep, which makes it read at a distance and in busy visual surroundings. The 360 degree Fresnel lens spreads that burst all the way around, so there is no blind side, and the low current draw keeps it easy to add to an existing circuit.

Magnetic or permanent mount: which MS1 do you need?

The MS1-110SP is the permanent mount version. It fixes in place and stays there, which suits a wall, a column, a machine guard or a door frame. The MS1-110SM is the magnetic version, and it holds on flat steel so you can move it between locations or use it for a temporary setup. The trade-off is the cord. A permanent installation hides it. A magnetic one leaves it exposed and needs clean steel to hold.

Is the MS1 a 110V or a 115V warning light?

Both numbers describe the same nominal supply. TriLite rates the MS1 at 110 VAC and specifies current draw at 115 VAC, and buyers search for it as a 110V and a 120V strobe. Standard building power in North America sits inside that band, so if your circuit is a normal 110 to 120 volt AC supply, the MS1 is the right family. Equipment running on 12 to 48 volt DC takes the MS11 instead.

What dome colors does the MS1 come in?

Amber, blue, clear and red. Amber is the general warning default. Blue and red often separate zones or conditions inside a facility. Clear gives the most raw output because nothing filters the burst, which is the common pick outdoors where the ambient light is already bright. Color conventions vary by site and by jurisdiction, so check your own policy before standardizing.

MS1 or MS11: AC or DC?

The difference is the power source. The MS1 runs on 110 VAC, which suits fixed installations on building power. The MS11 runs on 12 to 48 volts DC, which suits vehicles and battery equipment. Everything else is close: both give 3 to 4 watts at 3.6 joules, 70 to 80 flashes a minute, the same 360 degree lens and the same four dome colors. Pick by what you are plugging into.

Strobe, flashing or rotating: what is the difference?

A strobe fires a short, very bright burst. A flashing light switches a lamp on and off at a steady rate. A rotating beacon spins a reflector to sweep a beam. Strobes carry furthest in bright ambient light. Flashing lights like the FF3 and FFLP keep the mechanism simple and the cost down. Rotating beacons like the MR3 give a moving beam that reads well in open areas.

Where is the MS1 used?

Anywhere a fixed point needs a warning signal on mains power. Machine cells, conveyor start-up, dock doors, gate approaches, process areas, plant entrances and outdoor equipment. TriLite rates it for indoor or outdoor use. Set the height so the burst clears racking and equipment and lands in the line of sight of the person you are warning. For a spot that changes week to week, the magnetic version saves you a second installation.
