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 is the new head


This light head is a direct replacement for the Surefire M600DF head. It can be used with the Modlite 18650 body or the smaller Modlite 18350 body. While lumen output is only 680 lumen the throw is about 400% greater than the M600DF.  This light head is best suited for situations where extreme throw is needed.

If you are on the fence about which light head to purchase we recommend the PLH light head 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. This light is an excellent choice for anyone needing maximum throw.
  • 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 18650/18350 high drain cells which can be found here. Runtime is about 80 minutes with 18650 and about 40 minutes with the smaller 18350 cells.

Do not stack 18350 cells into an 18650 body this can cause the light to malfunction. Only use 18650 cells in 18650 bodies and 18350 cells in 18350 bodies.

    The OKW throw is incredible and definitely the best choice of light for a rifle with magnified optic. Quick shipping as well, cant beat big Tex!

    I have the plh v2 and the OKW. If I was to pick one it would be the OKW. The spill is not as distinguishable between the two as the throw. So in my opinion why not get the OKW. It’s truly incredible how well it works. Video and pictures don’t do it justice. You really have to see one in person to really understand how great it is.

    For inside of 100 yards or so I prefer the PLHv2, but past that, OKW all the way. That’s not to say that the OKW performs poorly inside of 100 yards, it still has wholly adequate flood. In fact, I’d take the OKW over the M600DF at any distance, including for home defense. But the PLHv2 is superior to the OKW out to about 100 yards.

    I have owned several Streamlight handheld lights and a few Surefire handheld lights, I can honestly saw there is no comparison when it comes to the Modlite OKW. What a huge difference with being able to see more, see further and more clearly in the dark. This is my new go to handheld light for patrol and I will be buying another one for my rifle shortly.

    By far one of the best light heads for a weapon or handheld light.. I use to be a surefire fan, but have made the switch to modlite and won’t look back. Don’t hesitate to pull the trigger on these high quality well built lights and heads

    Everything from modlite is awesome. Big tex has awesome customer service and shipping

    I’m at 5 modlites now , so needless to say it’s my favorite light on the market. I can PID out to 200 yards fairly easily with the OKW. Definitely a must to have on your blaster or even in handheld configuration.
