Eagle670 670nm Red Light Therapy for General Wellness 8mW/cm2-130mW/cm2 | USA Lab Verified 670 nm Flashlight (LED) w/Spacing Tube | Easy on The Eyes - no Blue Light v1.0-3.0

I bought this for red light therapy on the eyes.So far it is a good product in terms of simplicity and effectiveness.The intensity is strong but still low enough to irradiate my eyes by two minutes.I cannot say anything about results because this takes more time to see effects.

I originally had an issue with the flashlight and seller went above and beyond to correct the issue. I did a second replacement of batteries, even though the initial batteries I installed were new, and got the flashlight to work. Seller, no need for the gift card as I am not returning this item 5 stars for great customer service and a good product.

When using any red light for therapy, such as eye therapy, you must know the light's intensity (measured in mW/cm2). Say you need 50 mW/cm2 for three minutes. The further away you hold the light, the less intensity (mW/cm2) you get. So to get 50 mW/cm2, you need to know should you hold the light 6" away, or 12" away, or 18" away, etc. If you hold it too close, you get too much and will reverse your gains and in extreme cases may damage a sensitive target such as your eyes. If you hold it too far away, you don't get enough and will not make any gains. So you don't just need to know the light is 670nm. You also need to know the mW/cm2 at a given distance such as 12" (preferably you need to know at what distance is the intensity 50 mW/cm2). The company (lightlaboratories.com) won't tell you. They make a big deal over how well they tested this light to ensure it is 670nm, yet they totally conceal the intensity (mW/cm2). They don't disclose it here, nor at other outlets where they sell this flashlight, and they have ignored repeated emails to multiple departments from me. Finally, the flashlight is a cheaply made LED light you'd find at a dollar store. Of course, you're paying for the finely tuned LED bulbs set to 670nm, but without the intensity (mW/cm2), it's useless as a therapy device.

I am using this for red light treatment of my eyes. The product works well and seems to provide the expected 670 nm wavelength for vision therapy. The only restrictions on its functionality are the lack of a 3 minute timer as recommended in red light vision studies and the fact that you can really only do one eye at a time. I still use this on occasion for extra treatment of my worst eye but have primarily switched to a pair of rechargeable red light glasses with a built-in 3 minute timer when I do both eyes. Those glasses do cost several times what I paid for this flashlight type unit, however.

Works great. Simple to use. As expected.

I bought this light to view my 14 pet tarantulas in the dark, because that is when they tend to ld their spidery things.Tarantulas cannot see red light, and after using this right up in their faces multiple times, I can say that is seems to be 100% red light. They have no idea if is there.It is bright and seems like a quality device... But this is one issue that I have using this further...Possibly from the light glare created off of the acryllic enclosures, but after using this for an extended period of time, my eyes see colors differently.The first time is used this for about 30 minutes I'm the dark watching Teddy, my Honduran Curly Hair tarantula molt. As I was climbing back into bed at 2:30am, I noticed that the nightlight down the hall looked very blue. I giggled to myself and immediately passed out the second my head touched the pillow.Now tonight I spent a good hour watching my girls eat after a feeding and do their spider-stuff using the light. Afterwards I notice that other red lights (such as my snakes heat lamps and my Hue lights) looked yellow. They have slowly started becoming increasing orange, but 4 hours later, they still look orange.I assume that I will be able to see the color red again when I wake up, but I don't think that I will be using this light again for anything other than short bursts.tl:drLight is awesome and better quality than I expected. 100% pure red light, but I have safety concerns and will discontinue routine use.

The brighter setting stopped working after a few uses. It appears to be a problem in the switch. The lower setting still works for now.

The media could not be loaded. I tried it out in my field. I turned it on knowing there were deer in the field about 50 yards away. Anyway turned it on shining on the ground first. Nothing ran off. So I thought maybe no deer were out there so shined it towards feeder. 7 DEER , 3 Racoons. They just kept eating never looked my way. So if you want a light you can see with and get to your stand and not give that big buck a chance at seeing you. Buy it. It’s also rechargeable. And the battery last a long time. Bought another one for my son. But if you watch the video it is stuck in a flash mode. Sent it back. Got a replacement FAST!! Great company. Great light. If you are a SERIOUS HUNTER. this is a must have light. I’ve tried it several times now on deer. They do not even look up. Nor stop eating. Even in flash TBEY can’t see it. At 670 nm I guess it’s true. Deer see it as black. So if it’s dark TBEY can’t see it. Highly recommend!!!
