ExtremeBeam M600 Fusion, SX21R Ballistic, SX21R Remote Pressure Switch

    Here are a couple of nice looking, solid lights from ExtremeBeam as well as a “silent” remote pressure switch.  ExtremeBeam shows their corporate headquarters in Utah, with the packaging of the lights indicating that they are manufactured in China.

    First up, the M600 Fusion.  This is a very solid feeling light, manufactured of aircraft grade aluminum and “double sealed” to be waterproof to 30 feet.  Smooth, aluminum reflector and Cree LED combine to throw a rated 600 lumens for a claimed 1300 feet.

    I measured 500, 200 and 20 lumen on high, medium and low and that is a good showing versus rating as most manufacturers rate using the “emitter lumens” rating and my ratings are “out the front.”.  The light also has a tactical strobe.  Operation is simple –  it comes on at the high setting then cycles to medium, low, strobe, back to high, etc.

    One night one of my cats ‘escaped’ and I used this light as a searchlight as I drove the neighborhood looking for her.   I was impressed with the brightness and the throw.  While you can ‘defocus’ the head and soften the very defined spot, this light’s most impressive attribute to me is its long throw.

    Nice clicky switch ‘inside’ the tail cap – the light will tail stand but still has a nice tactile feel to the switch.  Light includes a split ring and lanyard (not shown) that attach to a hole in the tail cap.

    The light utilizes a large, deep, smooth aluminum reflector for that  previously mentioned long throw.

    Power is provided by 2 CR123 cells, Rechargeable cells, or 1 18650 cell.  ExtremeBeam sent along a couple of packs of their branded CR123 cells

    My sample weighed in at 10 ounces with batteries installed and as already mentioned, this is one solid feeling light.

    Also for consideration is the SX21R.

    From the ExtremeBeam web site, “The SX21R Ballistic was made to take a beating and come out on the other side ready for another. The lights extra-thick housing is machined from solid bar stock aluminum to ensure attention to quality craftsmanship, as well as protection from jarring impacts. And because the SX21R Ballistic is fitted with ExtremeBeam’s proprietary Anti-Recoil® System, the flashlight is weapons mountable up.50 BMG – further ensuring its durability for the most hard-hitting and demanding of environments.”





    The light does have a very solid feel, and is rated at a single level of 308 lumen.  My sphere does not do a good job measuring the output of lights that have such concentrated throw – I’ll stick with the manufacturer’s rating as it seems reasonable.   This light uses a deep reflector similar to the M600, but is obviously smaller. It also has aggressive crenelations on the bezel.   I’ve used this light a few times and it has a VERY concentrated beam – amazing amount of throw.

    The light has a nice feel in the hand, and includes a decent ballistic holster

    Love firearms and flashlights – and they go well together. I’ve been admiring and writing about quality flashlights for about 10 years…built my own integrating sphere….done a few mods. Proof positive that a 60 year old can still love toys!
