User questions & answers

Question:

Can i recharge this with usb

Answer:

Most disks -- just like internal storage -- take up a considerable amount for the device you put it in to recognize it and for other things. When you bought the device you're using, it has taken storage space, too. For example, a Kindle Fire will have taken between 3-4 GB already, brand new. In your settings, did you set it to store any apps that may be eligible that were already installed before you installed the card? I think I had four and another later. If you click on the card itself under Storage, it will list what's on it now and how much disk space each is taking. I don't know if you're using it for a laptop, android, phone, camera or a Kindle, so I can't be more specific. This article, even though it's regarding a camera, explains about binary storage being different than KB, MB, GB, TB, etc., so it takes up more memory than how we think of iit straightforward. Hope it helpss. I'm no expert on this sort of thing either. https://www.diyphotography.net/memory-cards-have-less-space-than-advertised-here-why/ I had to type this in myself because it wouldn't paste it into this. I did double-check it, though. I hope it helps.

User questions & answers

Question:	Hello. In numerous photos, I have see the Sky used off to the side, pointing at the face at an angle (like the photos above). Is this OK
Answer:	According to the book "Winter Blues" by Norman Rosenthal, one of the docs involved in the original discovery of seasonal affective disorder; the light can enter the eyes at an angle or from the sides. As long as the light waves are reaching the retina that's all that's necessary for it to work, and is even preferred in someone wearing glasses as light can enter the eye from the side without having to pass thru the glass lens which will filter a small part of it out. Also, wearing sunglasses filters even more light out and lessens effectiveness.
Question:	Can you adjust the height, independent of the angle? I mean, not the angle but just the height by itself
Answer:	You CAN adjust the height and keep the angle the same. The light swivels forward and back which changes the angle. However, the arm that attaches the light to the base also swivels forward and back to some extent. You can lower the height about 8 inches and still keep the light at the angle shown in the picture.
Question:	How long do light bulbs last when you use it 30 minutes a day? How quickly can you get the new light bulbs from the company? Available elsewhere
Answer:	The bulbs are rated for 8,000 hours, but the intensity does degrade over the bulb life. Therefore, you should replace the bulbs every two years, based on your usage, to maintain the same lux rating. However, even though the lux level drops over time, you may also simply increase the treatment time to derive the same therapeutic benefit (e.g. 10,000 lux for 30 minutes, 9,000 lux for 35 minutes). The bulbs retail for arounf $10 each and the Sky uses 2, which may be ordered from Carex directly or from other dealers.
Question:	Is the technology flicker free
Answer:	Yes. I don't know about the whole therapy aspect, but this is the single best task light I've ever found. The light is both glare and flicker free, and easy on the eyes. One thing they don't make very clear is that it has a brighter therapy setting and a lower task light setting. It will only stay on the therapy setting for so long, then one of the two bulbs clicks off. There is still an amazing amount of light left as a task light, but it can be worrisome when your brand new light does something odd. :)

User questions & answers

Question:	Does this product include infrared or near infrared lights? if so how many and what is the nm depth and nm depth of each color
Answer:	No
Question:	How does device stay propped up, if used on face/neck
Answer:	Needs batteries
Question:	Must u wear protective eye wear with it
Answer:	Your aube th111gfci-p 120 vac thermostat can control a resistive load of up to 2000W @ 120 V - the Honeywell TH115-AF-GA appears to be designed for a load of 1800W @ 120 V, that is, slightly less. If your electric floor heating system draw less than 1800W you should be good to go. However, you may want to figure out why the previous thermostat died... if it died because of overload the Honeywell TH115-AF-GA will not work.
Question:	What are the wave lengths on the other colors? I only see the red is 640nm
Answer:	The sensors that I have used with this thermostat are the Honeywell models. I always run a backup sensor also, just in case. For $10 it's worth it. The sensor is available for less in places other than amazon - just google the part #. IMO - The sensor should match the thermostat, not the floor mat. But you would have to check w/ Honeywell to see if one from suntouch is compatible. Personally, I wouldn't take the chance since at best maybe you got one included with your mat and you'll spending $20 for 2 Honeywell models. Is it really worth any risk at all to save $10? Bottom line, you would have to check w/ Honeywell to see if it is compatible. But why take the chance? I'd be surprised if Honeywell would tell you that any sensor other than theirs is approved and tested for use but ... you can try. Did you ask Suntouch? If they only make mats and not thermostats then maybe they've done testing with different combinations. That's a good place to check. Still it's not much money and IMO - you need 2 sensors in case you have a failure - either over time or during install. Sensor wires are THIN and fragile - unlike the heating wires themselves. It wouldn't take much to nick one.
