Description

This is one of the newest professional grade tactical LED flashlights from MF Tactical — the 5-mode MF Tactical CSI, which is the brightest and longest running flashlight we have ever built using the Cree R5 emitter.  This penlight sized flashlight is built from solid military grade aluminum specifically for the needs of law enforcement officers, crime scene investigators and anyone else who needs to carry a high quality flashlight with them to do their job.  While it is built to professional specifications, it is intended to be reasonably priced and therefore just as useful to anyone who needs a high quality, compact and powerful LED flashlight that easily fits in your pocket.  With a body diameter of just 0.8″, a head diameter of 1.0″ and a length of just over 7″, this compact professional tool has all of the right stuff to be your “don’t leave home without it” pocket penlight.

The MF Tactical CSI runs on two 14500 li-ion rechargeable batteries.  The Cree R5 emitter is so efficient that we were able to engineer this flashlight to run for up to 3-1/2 hrs. on high on a full charge and an incredible 15 hours on low.  While the price shown above for the flashlight is without batteries, just check the box marked “Select Battery/Charger Package” when you put this light in your shopping cart, and you can choose a package made up of either two or four rechargeable li-ion 14500 batteries and/or a charger.  We also offer a custom ballistic nylon belt holster/case.

Some of the design features that went into the MF Tactical CSI in order to make it the natural choice for professionals who rely on their flashlights was a flexible steel pocket clip, a textured diamond patterned surface to provide adequate grip when working in wet locations, waterproofing to IP-X 6 standards to protect your investment and make it safe for use on a boat or in the rain, and a five mode tactical switch (high, medium, low, strobe and SOS) with excellent tactile feedback and placed perfectly at the top end of the flashlight just where your thumb naturally falls.  We also included flash memory so that the flashlight’s circuitry will remember the last mode you used and return to that mode each time you turn it back on, avoiding the hassle of having to cycle modes each time you use your flashlight.  Lastly, like all high quality machined aluminum tools that are built to last, it is finished with hard military grade III annonization to protect your professional grade flashlight from wear and protect its finish from the elements.

MF Tactical is a US company based in New Jersey that designs and builds high quality tactical LED flashlights that outperform and sell for less than similar models offered by the larger flashlight manufacturers.  For example, if you compare the CSI to the Streamlight Stinger, you will find that you can get an MF Tactical flashlight, complete with an optional battery/charger package, for about half the price of the overpriced Streamlight.  In addition, when you chose the CSI you get a flashlight that is brighter, runs longer on a charge, uses modern li-ion battery technology (instead of the older NiCd or NiMH batteries that quickly lose charge capability), has better waterproofing, a full one year warranty and the high level of personalized customer service that keeps our customers coming back.

SMO Reflector Option:

If you would like to upgrade your  MF Tactical CSI to give you a more concentrated center beam and maximize the throw distance of your flashlight, we offer the option to upgrade your reflector to a highly polished SMO smooth reflector. The standard OP or “orange peel” reflector has a textured surface that acts to more evenly disburse the light over a wider field, which makes the light have a bias towards flood or spill. As some users prefer their light to have a bias towards throw, which concentrates more of the beam towards the center, sending more of the light farther down field, we offer the option of upgrading your light’s reflector to an SMO reflector.  Think of the difference as the choice of loading your home’s light fixture with a spot light bulb vs. a flood light bulb.  If you would want to maximize your light’s throw potential through the use of an SMO reflector, just check that option box when ordering to upgrade your standard OP reflector to the SMO reflector.

The upgrade option replaces the standard OP reflector in your flashlight with the the SMO. The CSI can be ordered either with the standard OP reflector or with the upgraded SMO reflector.

    Not going to use curse words. Butt I cannot believe I bought 10 x700 Japanese junkers. I need a boot up my derriere. Bought them for Christmas presents and they didn’t come with batteries. This light here is more better than my other light I own from another manufacturer American made., and it puts out more power with more modes. I sometimes think I have the word fool tattooed on my forehead.

    I also did plenty of research before getting a new flashlight and Monster came up as the winner! Excellent quality, very helpful and courteous customer service. Looking forward to buying another light in the future…

    Have had my CSI for about 2 weeks now and wanted to live with it for a couple weeks before writing a review. This is my first MF Tactical light but wont be my last. I am a plain clothes police detective and I needed a light that would be small and light enough to stick in my jacket pocket without weighing me down. This CSI is everything they said it would be and more. I put it next to my mini MAG, and there is just no comparison. The Monster has got to be at least 20 times brighter than the Mag, and I still get a full week of use out of just one charging of the batteries. (The MAG has just made early retirement in the wife’s glove compartment). The flashlight, batteries, charger and holster shipped 10 MINUTES after i bought online and then arrived in just 2 days. Right out of the box it looked and worked great. couldnt be happier and will definately be back for a powerstar before my first overnight camping trip with the kids this summer.
