I have recently purchased a Modlite PLHv2 and love it.  I am using a Surefire SR07 that I already had.

Now I am looking to maybe pick up another PLHv2 and ran across a warning on the Modlite page:



Modlite ModButton Lite (Surefire®/Modlite Plug)

Moving to the ModButton isn't that big of a deal provided that they are in stock (and the Modlite is right now).  But I also want to have a constant on/off capability on the switch, which is one of the things about the SR07 that appeals to me.

I am also not crazy about the small buttons on the ModButton and Hot Button.  That is almost reminiscent of pushing the tailcap of a flashlight.  Does anyone remember when those things ruled, and if someone suggested a tape switch they would be told that it was "too complicated" and "fragile"?  Seems like things have come full circle.  LOL

How much output is lost on a modern light like the PLHv2 by using a Surefire SR07?

And are their any modern tape switch options available that integrate momentary/on/off?

Thanks,

Corey

Personally tested side by side with fresh battery and it's just enough to notice but it's not wow. Mod button is good stuff but I stuck with surefire because it sits lower and I liked the ergos better even though the mod button is better.

So I'm losing some output, but not a lot huh?

The PLHv2 is an amazing light.  Even at whatever percentage of output I am currently getting.

It's only noticeable if you are really looking for it.  I wasn't sure,  wife said she could see the difference.

Not sure if it's a definitive test, but I run a DS tailcap and there's zero difference in output whether I click the switch or the tailcap. Also, I want to say that the majority of the issues with lower output had to do with the ST switch.

Why would a DS switch not suffer from the same issues?  Do you think when the circuit is open (on) the issues are not present?  (Honest question.)

If the issue is mainly with the ST switch, would the same not apply to the momentary function on the SR-07?

From what I've read, the power loss comes from the ST switches. They say the SR switches and DS tailcaps are GtG.

Good to know thanks. Got a source?

I can't tell on my Sr07 switches
I might just grab a couple modlite heads and run them on my DFs that are completely set up to use.

I did some playing around with my DS tailcap, SR07 and modbutton lite, and couldnt tell a difference on my older PLHv1. I'm also a pleb so maybe that was just me.

Thanks. I am trying to avoid the DS because it is pretty large and hard to operate constant on moving off of the pressure pad. I really like the SR-07 switch.

I rescind my prior statement. I was under the impression that the legacy switches were the ST switches. I have done more research and from everything I can find, the SR07 & SR07 D IT switches will slightly reduce overall power, as well.

Thanks, got a link that I can check out?

Sooooo, when is Modlite going to introduce a switch with momentary/on/off?

https://www.bigtexoutdoors.com/surefire-scout-tailcap-tape-switch-product-guide/ , this was one of the places I read that the SR07 will cause slight power loss. I googled - "is there power loss using sr07 with modlite head", and found lots more info, as well.

Thats an excellent 2nd question. I would really like to know this answer, and also when will they introduce a switch like the SR07-D-IT. Which would run the higher output light plus an atpial.

Thanks, I'll check it out.

The Unity Hot Button allows momentary/on/off. Just dont fully depress it to the "click" for momentary, then click for constant on, and again for off. Not perfect, but works in my experience.
