## Questions & Answers

**Q: does it come w any manufacturer specification that says the flash light is 670nm?**
A: Hello, thank you for the question! The flashlight does not come with any paper specifications it is just the box and flashlight. However under the barcode on the box the printed text contains "670nm" so you would be able to tell that way. Thank you!

**Q: Does this light damage the eyes?**
A: No it does not. According to the latest studies, Deep Red Light in the 670nm Range can actually be beneficial for the eyes in certain age categories. Always check with your Eye Doctor before trying Red Light Therapy.

**Q: Where is it made?**
A: These were made in China.

**Q: Does the beam stay 2 inch narrow or it will create a cone as focal distance increase?**
A: I don't think it creates a cone - but I have to admit I got confused using it. I wanted to use it for eye health and then worried I was using it wrong and I would damage my eyes so I have put it away until I know more about how to use it safely...
