## 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.
