The Modlite heads are undergoing an in-line upgrade. The new head is slimmer but still provides the same output and runtime as the original heads. Performance is NOT affected. This light will ship with the new head.


The Modlite OKW-18650 Weapon Mounted Light Package contains an OKW light head, 18650 body and tail cap. It also includes two KeepPower 3500mAh 18650 batteries and a Nitecore D2 charger. While lumen output is only 680 lumen the throw is about 400% greater than the Surefire M600DF.  This light head is best suited for situations where extreme throw is needed.

If you’re on the fence about which light head to purchase we recommend the PLH light package which is available here.


  • Hand assembled in and tested in the USA.
  • Lifetime guarantee
  • Approximately 680 out the front lumens and candela is approximately 69,000. It is an excellent overall light head good for indoor or outdoor use.
  • 6061 Series Alum bezel with Mil-Spec Hard Anodizing.
  • Ultra clear BOROFLOAT® lens allows 98-99% light transmittance.

Lithium CR123 cells are not supported and if used will cause the cells to heat up and possibly explode or catch fire. We recommend the KeepPower 18650 high drain cells which can be found here. Runtime is about 75 minutes with the supplied 18650 cells.

7 reviews for Modlite OKW-18650 Weapon Mounted Light Package (New Slim Head)

  1. Jesse (verified owner)

    The OKW offers a greatly increased hotspot over other WML’s, thus allowing better identification at increased distance. It has replaced my Surefire Duel Fuel light as my primary light source on a defensive rifle.

    Buy it, you will not regret this purchase. As always, Big Tex shipped lightning fast and has the best customer service out there.

    When I first received the light, I thought I fell victim to the hype surrounding this light. I decided to test it out for several night-fire events and shot roughly 1k rounds through my patrol rifle with this light mounted. I decided to try it for awhile on the patrol rifle, honestly expecting to take it off and put the M600DF back on in its place. Two nights later, I was very grateful for the long range punch of this light, and it was instrumental in an incident with an armed felon. I no longer have any second thoughts about this light for patrol use.

    A must have for any rifle running a LPVO, despite only putting out approximately 680 lumens the throw from the 69,000 candela is insane! Night and day difference between the OKW and the SF m600df. Also comes with an awesome nitecore charger and two keeppower 18650s such an amazing deal!

    This review is more on the customer service I received from Big Tex vs the OKW (don’t get me wrong, it’s an awesome light per the other reviews). My OKW was delivered on a Friday. I figured out pretty quickly that one of the batteries were defective and would not register on the charger. I emailed Big Tex the next day on Saturday and had a response by Sunday evening. After a brief exchange via email, replacement batteries were shipped and on the way via UPS. Huge thanks to Big Tex and the customer service group there!

    I struggled with myself for months about spending the cash for a modlite. In a moment of weakness I snagged the OKW and boy am I glad I did! I am amazed at the light output and highly recommend this light to anyone! The only downside is how long it takes to charge the batteries.

  6. Chee (verified owner)

    OKW is a must have for any LPVO rig or any situation requiring extreme throw. Awesome light, feels like I’m holding a lightsaber!

    Best weapon mount light I have ever bought especially paired with the Modlight Modbutton. The long distance throw of the OKW is amazing.

    Thanks to Big Tex for the fast shipping.
