Wondering what people think of this new light gadget which is supposedly not only great for jet lag, but for energy throughout the day as well?
The sun is safe. $270?!
Hey Eilee, the Valkee has been around for a number of years now. It's pretty much been exposed as a complete scam. http://earlightswindle.com/story.htm
They've been trying to validate their oversized claims and have yet to do so imo. The 'study' they site is of questionable quality in a low impact journal. Their device is actually just two 448nm LEDs emitting 4.3mW of power at 1cm away. You could purchase similar LEDs for about $2 instead of $269 if you really wanted to test it out.
Here's the "study": www.humancharger.com/r/study/
Sorry, the quotes got a little messed up in the copying/pasting but they should give you an idea of the device and results.
"Interestingly, a significant effect of TBL was not observed until post-travel day 4, which may indicate a cumulative effect of the TBL treatment."
"The TBL group reported a significantly lower VAS score on post-travel days 4 and 5 ( P 5 0.0071 and P 5 0.0403, respectively) and a trend toward significance on post-travel day 6 ( P 5 0.0685) compared with the placebo group."
"The bright light (luminous fl ux: 3.5 lm; illuminance:9100 lux measured at a distance of 1 cm; irradiance: 4.3 mW âˆ™ cm 2 2 measured at a distance of 1 cm; photon density:1.13 3 10 16 photons âˆ™ cm 2 2 âˆ™ s 2 1 ) was produced using white LEDs with a peak in the short-wavelength blue region at 448 nm."
