## Questions & Answers

**Q: What is the risk of radiation? Is it safe to do an eye exam with?**
A: The risk of radiation is type RG-2. This is a form of radiation caused by the Brightness of the LED. The Brightness can lead to Permanent Damage to the back of your eye (retina), which can cause one to enter a category of Blind.

For example: In the Entertainment Industry, for over 10 years, lighting professionals have been prohibited from looking directly at the LED while it's on, because this will immediately cause one to develop a category of Blind.

**Q: I'm having an issue with the toggle on/off switch. Where do I send it back under the warranty coverage?? Only had it three months.**
A: The switch on these 66118 lights are horrible. I had to replace the tail-switch every 12months @ 6.89ea. It was cheaper and faster to just order 2 new tail-switches here on Amazon than it was to send it to Streamlight for repair.

**Q: Can this be easily concealed in my prison wallet?**
A: It’s quite slender so it will fit in your prison pocket quite nicely. Although on some occasions I have noticed a slight discomfort.

**Q: Is this the 90 lumen version ? Or the 70 lumen version. Stream lights website promotes the 90 lumen and this says 70?**
A: The packaging says 350. The listing says 350. If you look up the serial number it should be 250, however the packaging matches packaging of those at 90 lumen. Very very fishy
