## Questions & Answers

**Q: New specs on Streamlight website is 45 lumens, is this 45 or the older 35 lumens?**
A: March 2022, it's 45 lumens.

**Q: Is this the newest version with 35 lumens?**
A: Bought my second Microstream on April 30, 2016. It was the 35 Lumen version.

**Q: can i buy a replacement end cap for this light? i bought it and love this light but the on switch is already worn out and the light goes off.**
A: Amazon sells the end cap switch (part number 660023) that fits both the MicroStream (uses 1 AAA battery) as well as the Stylus Pro (uses 2 AAA batteries). Right now it is $6.96 + tax. I was about to order a new switch when I thought I would see if they are usable in either light. The alkaline batteries that came with my Stylus Pro leaked and damaged the switch. Now I will be using NiMH batteries in the Stylus Pro like the one I am using in my MicroStream.

**Q: does it have hat clip**
A: I received mine this week, October 2020 and it is 250 lumen and has a combination hat/pocket clip.  Very nice light.

### ⭐⭐⭐⭐⭐ Perfect EDC for Me

### ⭐⭐⭐⭐⭐ Nice and compact.
*by S***E on December 2, 2025*

Seems sturdy enough. It throws off a good amount of light for its size. Nice flashlight to throw in your night stand or car console for emergencies.

### ⭐⭐⭐⭐⭐ Excellent Little Flashlight
*by N***R on September 22, 2025*

It's bright and the battery lasts plenty long; it's durable, and I don't worry about it's getting damaged. I have a canvas leatherman pouch I keep on my belt; it has loops on either side of the the leatherman tool holder itself. In one loop, I keep a ratcheting extender. In the other loop, I keep this flashlight. I can leave it in the loop and press the button when I need to illuminate things I can point at by moving the holder slightly. This happens fairly frequently as I help my elderly parents up and down the outside stairs and it's helpful to be able to light them up. It is very nice to have access to a bright light source all the time, and this flashlight makes that easy.
