MDM4 M91B-SureFire Millennium Adapter

This turnkey package includes a Malkoff MDM4 Adapter and a Malkoff M91B Drop-in.  The output is 1000 Lumens momentary and 900 Lumens continuous.  The M91B provides a broad, floody beam with 8500 candela. It will illuminate objects out to 200+ feet.  The current draw is approximately 1400ma at 9 volts. The full output runtime is approximately 30-45 minutes on three CR123 primary batteries with a nice long taper as voltage drops.  The LED is a cool white (5700K) Cree XP-L.

The Malkoff MDM4 Adapter will fit most Surefire Millennium Series Lights including the M3, M4, M6, M500, M961, M962, M900, and M910.  The M900AB and M910AB (rail mounted vertical grip weapon lights) may additionally require a spring for the tailcap so the batteries can be installed with the negative toward the tailcap.  Please request the spring in a follow up email to  cathy@malkoffdevices.com  after checkout.  It will be included in your order for no charge. 

MDX/MDM4 Tempered Glass Lens Kit (Ultra Clear): The tempered glass kit will be installed if purchased on this page. This is a 26.4 x 1.6 mm Tempered and AR Coated (UCL) Glass Lens for the MDM4 Adapter. Visible Light Transmissibility is 98%. This lens is chemically strengthened, aka chemically tempered, as opposed to heat tempered. High temperature resistance compared to standard acrylic lenses. It is more scratch resistant that float glass. Sold HERE.

This Item is Covered by Our Lifetime Warranty. 

Things to Know Before Purchase:

The maximum input voltage for the included M91B is 12v.  It is suited for use with up to four primary CR123 batteries or three rechargeable Li-ion cells.  It will work in the Surefire M6, as the M6 is actually a 9v light even though it has 6 batteries.

The MDM4 WILL NOT FIT the Surefire M951.  For that model please see the Malkoff M951 Adapter.

The MDM4 will allow for the use of a Malkoff M Series Drop-in in any Surefire incandescent light which uses the stock incandescent MN10, MN11, MN15, MN16, MN20, MN21, MN60, or MN61 lamp assemblies. Please check your bulb before ordering.

WARNING: This light is capable of causing eye damage at close range. Please use the light responsibly!!!
