UPDATE: Surefire has affirmed that all current Surefire lights should be waterproof to about 33 feet/10 meters. Some reviews were posted before Surefire made the affirmation that their lights were watertight to 1 atmosphere depth. Any new Surefire lights you purchase now should be considered waterproof to 33 feet/10 meters.

Short Description:

The M3 Millennium Combatlight is a heavy duty tactical flashlight made by Surefire.

The body of the M3 is made of machined aircraft aluminum which is anodized to military spec. Type III hardness. Inside, the entire light body is coated with a corrosive resistant layer. Checkering is found on the tailcap and the body just behind the head to improve grip. The unusual shape of the body is designed to facilitate using the Rogers-Surefire combat grip when engaging opponents. There are 2 rubber rings near the tail of the light that allow for adjustment of the grip so that the light fits the hand of the user when using the Rogers-Surefire technique.

The bezel of the light includes a shock dampening system to allow the lamp to survive repeated impacts arising from the recoil of heavy caliber weapons. It also protects the lamp when the light is dropped on its face. The light comes with two lamps - a 125 Lumen lamp for 1 hour runtime on a set of batteries, and a 225 lumen lamp that runs for about 20 minutes on a set of batteries. Three Surefire 123A batteries are included in the light. The lens is tempered Pyrex

The tailcap contains the switching mechanism. Press the rubber button for momentary use, twist the tailcap for constant-on. The tailcap has witness marks to help indicate the state the switch is in, and the switch can be "locked out" so that accidental activation is prevented. A lanyard attachment ring is just below the tailcap. A lanyard is included. The entire light is sealed with O-rings, making it very water resistant.

Detailed Information:

If you're "in up to your neck in crocodiles", and you need a REALLY good light, this is it. Designed specifically for law enforcement and military, it uses the components, design, and ergonomics best suited for folks in those professions. This is no "carry around in glove box in case I get a flat tire" light. It's a very serious tool with a very serious purpose. In low-light situations it has the output potential to momentarily disrupt a subject's vision long enough to give the advantage to the light's user, putting the subject on the defensive and making it difficult for them to identify a clear target. For the uninitiated, this means that if a "bad guy" is hiding in the dark getting ready to shoot at a "good guy", a blast from the M3 at close range can startle his eyes enough to give the "good guy" time to take the first shot, or at least give the "bad guy" pause to think twice. The world is not a fantasy-land where everyone is nice, happy, helpful, courteous, and kind to strangers. In certain situations some people will try to kill you, and the M3 is a tool to help prevent that from happening when used in conjunction with the proper equipment and training.

Now, if you're not prone to wind up in those types of situations because that's not your profession, the M3 is simply one very durable, very bright, kick-butt light. Designed for the extremes of combat, it should be able to take just about anything you can dish out when camping, caving, climbing, hiking, or anything else. However, it is not a dive light and is not intended for prolonged submersion at any depth.

The body of the light looks like it is a very unusual shape to anyone unfamiliar with the way a combat light is held. It's commonly held between the index and middle finger with the momentary button against the meaty base of the thumb on the palm. The fingers grip the light at the narrow section of the body. Squeezing inward on the flanged rubber grip ring forces the light back against the base of the thumb, depressing the momentary switch. The lower two fingers on the "light hand" can be used to grip the base of the "weapon hand" giving more stability to a firearm while engaging opponents. The rubber flange is backed by two rubber rings that can be stretched and removed to allow the light to fit a particular user's hand better. Of course, you can hold it using various other grips, all of which are surprisingly comfortable despite (or perhaps as a result of ) the unusual shape of the body.

The body finish, both inside and out, is manufactured to military specifications, giving the light very good resistance to abrasion and corrosion. Fins are machined into the body near the head to help dissipate heat that is generated by using the high intensity lamp assemblies. The bezel has a notice engraved upon it warning that it should be considered a hot surface. Don't grab the light by the bezel if it has been on for any significant period of time.

The M3 accepts the MN10 lamp, producing 125 lumens for 1 hour on three 123A batteries, and the MN11 which produces 225 lumens for 20 minutes with the same set of batteries. The lamp resides inside a shock isolated textured aluminum reflector designed to survive sharp, hard longitudinal impacts. The contents of the bezel are protected by a tempered Pyrex lens designed to withstand the high temperatures and thermal cycling resulting from using the high output lamps. Both lamps are included with the unit.

If you need to use this light for long distance spotting instead of close quarters combat distances, you can purchase a "Turbo Kit" separately which includes a replacement head and lamps that focus the light into a much tighter beam.

The switch is a "standard" tactical-style switch. Press the textured rubber end button for momentary activation, twist the tailcap for constant-on. The tailcap has a witness mark that matches a similar mark on the body. This helps indicate the state the switch is in. With the witness marks aligned, a quick twist of the tailcap between the thumb and forefinger (while the rest of the fingers hold the light in a bezel-down position) will turn the light constant-on. Twisting the tailcap backwards 1 full turn until the witness marks align again locks out the switch so that accidental activation is prevented. A lanyard ring is found between the tailcap and the body. A nice nylon lanyard with two spring loaded cord sliders and a clip is included with the light.

For batteries, 3 Surefire 123A lithium batteries are recommended and are included with the light. They can be purchased on-line at Surefire.com for a very reasonable price ($1.25 each at the time of this review). I do not recommend buying 123A batteries in local stores. Even the nationwide "discount" department stores sell them for $10 a pair.

This light does not have a clip on the side as it is not intended for pocket carry. Quick access belt sheaths are available.

What I Liked: Very bright, tough finish on the outside - no need to worry about babying this light, shock isolated lamp, ability to upgrade to a brighter lamp assembly or a Turbo Head for distance spotting, nice lanyard, adjustable grip, very water resistant.

What I Didn't Like: Not a darn thing.

Other Things I Noticed: The beam was quite oval. This may be the result of several different things including the long filament in the bulb and/or the lamp assembly being slightly off center. Close observation shows that the filament is slightly off center in the glass lamp envelope. However, the glass lamp envelope was placed (purposely?) slightly crooked in the lamp assembly base which compensates for the anomaly; so the filament is actually centered in the reflector. In practical use at close quarters combat distances, the shape of the beam is inconsequential. More important than the shape of the beam is the clarity, so the lack of holes and gaps in the beam takes precedence over having a perfectly round beam.

Conclusions: For a serious job, you need serious tools. This is definitely on the "upper end" of serious. If you really need to punch holes in the darkness, the M3 Millennium Combatlight is a great choice.

UPDATE: As requested:

M3 with HOLA:

10,000 Throw (100 comparison chart number)
15,000 Overall Output (150.00 comparison chart number)

That was with very slightly used batteries, so it may start out just a touch higher.
