UV LED Phototherapy Systems









Latest News Release: July 31, 2009, Albany, NY

TanThera, Inc. ("TanThera") is announcing the receipt of U.S. Food & Drug Administration ("FDA") letter dated May 29, 2009 indicating a clearance for the TanThera-T35 UVA1 Light Emitting Diode Tanning Chamber Section 510(k) premarket notification application stating "Indications for Use: Intended to provide ultraviolet light to tan the skin."

The TanThera-T35 is TanThera's flagship LED Tanning bed design, which would be produced in limited quantities for evaluation by qualified customers only.  TanThera believes that it has advanced the state-of-the-art in tanning devices by incorporating UVA1 LEDs that are optimized for tanning without producing the UVC, UVB, or UVA2 spectral lines emitted by mercury-vapor tanning lamps commonly used in other tanning devices.  UVA1 is closer to blue light, whereas UVA2 is closer to UVB.  Since UVA1 is less energetic than UVA2, UVA1 is thought to be less damaging than UVA2, UVB and UVC.

TanThera intends to promote the use of more precise terms to reduce the confusion surrounding ultraviolet light caused by the broad definition of the terms UVC, UVB, and UVA, which have varied in the scientific literature.  Within a single range, the effects of different wavelengths can be vastly different, which causes additional confusion.  The confusion resulting from the blurring of the specific wavelengths has created on-going debates over health benefits and risks associated with ultraviolet light.  TanThera believes that much of the conflicting advice related to ultraviolet light would be resolved if the terms UVC, UVB, and UVA were abandoned in favor of more accurate descriptors.  

The term UVC is defined herein as light from 100 nanometer ("nm") to 280 nm.  The term UVB is defined herein as light from 280 nm to 320 nm.  The term UVA is defined herein as light from 320 nm to 400 nm.  UVA is often sub-divided into UVA1 and UVA2.  The term UVA1 is defined herein as light with wavelengths from 340 nm to 400 nm.  The term UVA2 is defined herein as light with wavelengths from 320 nm to 340 nm.

TanThera is a New York state corporation which has a mission to commercialize UV LED tanning products and services.  TanThera is a wholly owned subsidiary of Opthera, Inc., also a New York state corporation, with a mission to commercialize UV LED tanning and phototherapy products and services.
