I look right into it, and others I've discussed this with online do also. Between 8-9AM, and for me I do it 3X a week, I do each eye for 3 minutes. I have only used it a short time, so I can't give a report yet, but It does feel good to do it. **Q: Can the brightness level be adjusted? I'm concerned that this light may be too bright to look at.** A: The brightness cannot be adjusted, but the farther away you hold it, the lower the energy at the target will be. You can also add a diffuser to reduce the energy. You can purchase a diffuser, or look into scotch tape or teflon tape as an option. Search "diffuser vs scotch tape" online. **Q: How do i use this " torch-like tube" to "emit energy equivalent to 40 mW/cm2 or 4.8J/ cm2 for 2 min" ???** A: 1.21 Jigga watts in a tri-phase capacitor, with a velocity at 88 mph. See you in the future! The answer is 42! **Q: This gets really hot. It has only been on a few minutes. I can hardly hold it. Is this normal?** A: The previous version of the flashlight occasionally had this issue. Our new updated model does not get hot. Please message us and we will send you the new version. ## Customer Reviews ### ⭐⭐⭐⭐⭐ einfache Handhabung zum Training der Augen *by A***T on 30 August 2023* habe die Lampe schon 2x benutzt mit ausgestreckter Hand kommt auch auf die Entfernung von etwa 65cm ob die Augen besser werden, kann ich noch nicht sagen, die Anwendung ist einfach (3 Minuten) ### ⭐⭐ Useless without buying expensive battery *by L***Y on 15 November 2022* ### ⭐⭐⭐⭐⭐ Not sure yet *by C***R on 26 July 2023* ## Frequently Bought Together - New Version! 670 nm Deep Red LED Light 8mW/cm2 | USA Lab Verified 670nm Flashlight (670 nm LED) w/Spacing Tube | Red Light Therapy 670 nanometers | Easy on The Eyes - no Blue Light - Revive - 670nm - Red Light Bulb Sleep Therapy by Gamma - Melatonin Promoting Natural Sleep Aid - Revive - 670nm - Red Reading Light Sleep Therapy by Gamma - Melatonin Promoting Natural Sleep Aid --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.hr/products/552302229-670-nm-deep-red-light-670nm-flashlight-670nm-led-red](https://www.desertcart.hr/products/552302229-670-nm-deep-red-light-670nm-flashlight-670nm-led-red) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-05-22*
