In this side by side comparison guide, let's check out Surefire M600DF VS Modlite PLHv2. I have used both lights extensively for low light training, and I slightly lean towards the PLHv2 for its impressive long range performance than the Surefire M600DF.
Essentially they are similar lights made to be interchangeable. Modlite PLHv2 offers higher candela output for long range illumination than Surefire M600DF

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.
Biggest Buying Decisions:
Get Surefire M600DF
- Mil spec weapon light right out of the box
- For long gun & sub gun use
- Want everything Surefire
Get Modlite PLHv2 for:
- Higher beam and candela output
- 3 popular heads to choose from (IR as well)
Lumen & Candela Comparison
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.
PLHv2 in action
The default Surefire KE2DF head is great for CQB and mid range illumination.
The best part about both of these lights are the interchangeability. Simply just swap the light heads and you are good to go.
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.
Standing at the same spot, now we can illuminate the area near by much better

For personal defense engagement distance, the Surefire M600DF and Modlite PLHv2 work perfectly for ID targets in the dark.
Both lights have neutral beam tint for accurate rendition in low light.
Modes Of Operation
There are tons of pressure switches available for the Scout light body.
The Surefire DS00 tail cap is highly recommended. It features allows pressure switch pad connection along with a secondary activation button.
The tail cap can also accept many other pressure switches like the ModButton, Hotbutton and TNVC TAPS

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 M600DF and MODLITE bodies are durable and parts are interchangeable. The key comparison here is the light head options.
PLHv2 head is way better for long range illumination with that high 54,000 candela output
Surefire KE2DF head is better for close range illumination with that bright flood beam.
