Snagged one of these the other day and I'm quite impressed with it. The standard Modbuttons have been total unobtainium since they launched in the middle of the pandemic, so when BigTexOutdoors dropped their exclusive "Lite" version, I snagged it up as I already have a scout mount.

The button activation is tuned nicely, being very tactile and completely silent.

ModLite claims that the switch will deliver full power to modern lights using high output 18650 rechargeable batteries (such as Surefire M600/M640, ModLite OKW/PLHv2, and Arisaka offerings).

Unfortunately I don't have any experience with Surefire tape switches to compare against, but I see no reason to get one with ModLite's current offerings.

As I noted above, this is my first set up with a tape switch, so any suggestions on set up is always appreciated. Pic below of my current layout.

Are they still momentary only? Or does it have a constant on capability? 
 

I hate momentary only switches....

The Modbutton is momentary only. You can get the Surefire DS00 tailcap to give constant on via the tailcap button, but I don't have experience with it personally.

Unity Tactical, who makes the Modbutton for ModLite, makes what they call the HotButton which may be more up your alley.

Pretty sure the Hot Button is momentary only as well.....

I have SF SR07 switches on my carbines now, but I like the smaller footprint of these new buttons.

I just looked at BigTexOutdoors and the HotButton is half-press for momentary and full click for constant. They have that in mlok and 1913 mounts. I almost snagged one but wanted something momentary only to play with.

Awesome! Thanks!

Out of curiosity, why the preference for constant on?

Because sometimes I need to do stuff with my support hand and I don’t want to do it in the dark.

that seems to be the way I see most of these run.
