Size & Weight

Surefire M600DF and Modlite 18650 bodies are very much identical as far as dimensions go.

The Modlite has slightly different machining profile without lot of markings on the body. Both light bodies feature scout mounting footprint to accept mounts that are already available on the market. 

The weight of both lights are pretty much the same, and Modlite is just 0.3 oz heavier, and it's not significant enough to feel the difference if the light is the only accessory you have on the firearm.

Lumen & Candela Comparison

We stress a lot on our website - Lumen intensity is important, but Candela is king for throwing the beam far to identify targets.

Higher candela output can punch through fog and overcome photonic barriers, and this is where the MODLITE PLHv2 absolutely beats the default Surefire KE2DF light head.

The way PLHv2's reflector is designed can throw the light far to help id targets at further distances.

Flood Beam

PLHv2 head has a much tighter beam with just enough flood beam to see what's around, but the Surefire M600DF definitely has a wider and brighter flood beam to lit up everything.

Durability

Both Surefire M600DF and Modlite bodies are aerospace grade aluminum construction. Under normal use the light will last you a long time.

The most vulnerable part is the light head, and almost all light heads get shattered when experiencing direct BB or simunition impact.

The threads are much tighter on the M600DF to secure the light head and tail cap.

The light heads are removeable, and the Surefire M600DF has a much beefier body than Modlite.

Overall, Surefire provides better warranty service if the lens breaks, and they will send you a new head. Same goes with Modlite.

Surefire KE2DF head is better for close range illumination with that bright flood beam.
