This FDE 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 PLHv2 light head which is available here.
Features
- 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 FDE 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 throw on this thing is amazing. The OKW head I still believe is the best duty use head and applicable for most people in most situations, I know the PLH gets a lot of praise as well as the M600DF, however the candela and throw is unbeatable on this. For outdoor use you are able to positive ID at long distances 100-200M and is great for an SPR setup.
