Is there really any medical benefit in using either of these devices?

Question

X-Light Infrared LED Pain Relief: The X-LIGHT is a small hand sized LED device containing 14 red, white, blue, and infrared LEDs arranged in triangles (infrared LEDs are invisible to the eye when they are on). The X-Light's red, white, blue and infrared LED's have pain relieving effects similar to the superior pain relief devices that, until now, have only available in physician's offices. The X-Light entices and prompts the body to instantly begin long-term healing. The immediate pain relieving effects are unsurpassed.

Qigong masters say the X-LIGHT emits energy very similar to chi itself (ki, qi, prana), our vital life force. A unique combination of colors (wavelengths), geometric designs, and pulsing settings are incorporated into the device. When the X-LIGHT is aimed at the hand, most people feel this unique energy as heat, tingling or a cool breeze. The X-LIGHT appears to be producing the energy balancing effects seen with qigong masters, making it is safe to try on almost any condition.

Answer 1

There is undoubtedly a strong placebo effect.

New Scientist magazine recently published some interesting articles showing the impressive strength of the placebo effect.

I wonder how they can align sets of four LEDs into triangles; and why they chose red, white, blue and infrared rather than a more logical and straightforward red, green and blue.

Answer 2

Uh. No. No. Not at all. There's no physical mechanisms for any of what they're claiming to happen.  

Answer 3

lol, no

Answer 4

REALLY????

Quack, quack, quack (and I'm not talking about a duck, either).

Don't you think that if they did that it would be in the headlines?

No ethical pain doctor or physical therapist would EVER prescribe such things unless vigorously investigated in double-blind, peer-reviewed studies.
