New, improved Glowbys with 25% smaller barrette for an even lower profile in your hair; 14" fibers, smaller CR1220 batteries. Otherwise, New Glowbys are exactly like the original Glowbys. Light up your hair with Glowbys fiber optic hair accessories! Glowbys sell elsewhere for up to $10 ea! Great for any nighttime event - prom, holidays, parties, nightlife, concerts, raves, festivals, weddings, and more! The ideal accessory for New Years Eve, Mardi Gras, St Patrick's Day, Burning Man, etc.! Glowbys are illuminated thin fiberoptic strands which clip to your hair to create many brilliant stars of light (50-60 fibers per Glowby, with the longest fibers 14" long). A small barrette (1.3" x 0.6") houses two small batteries (BATTERIES INCLUDED) and a light source, which lights up the ends of the fibers. GLOWBYS ARE REUSABLE - you can wear them again and again. Just change the batteries when Glowbys become too dim, typically 8 hours. Slide lid slightly open to turn on/off. Wearing Glowbys - Wear the thin barrette under the hair so that only the lights are visible. Attach underneath the top layer of hair. The barrette will be covered, but the Glowbys lights will still be visible. Glowbys are 15" long, but can be cut to any length - a star of light appears wherever the fibers are cut. Glowbys come in a cascade cut pattern, but they can be arranged in almost any pattern depending on the your hair style - use your imagination! Hair Stylists - just attach Glowbys and treat the fibers like strands of hair - cut, loop, etc. Caution: Do NOT use a curling iron or hair dryer on Glowbys; HIGH heat will melt the optical fibers. Note that some of the pictures show girls wearing multiple Glowbys. In particular, the girl with pigtails in the first picture is actually wearing 4 Glowbys - 2 blue and 2 white on either side.

Description

DPL Therapy LED Light Treatment Pain Relief System is for the treatment of pain, relief of muscle and joint aches, sprains, back pain and the pain and stiffness associated with arthritis. The DPL System uses a form of energy called Photons to penetrate deep into the body easing pain and repairing damaged tissues. The DPL Therapy System is a non-invasive, drug free therapy which can be applied to your specific and individual needs. Light therapy has been shown in over 40 years of independent research worldwide to deliver powerful therapeutic benefits to living tissues and organisms. Both visible RED and INFRARED light have been shown to affect at least 24 different positive changes at a cellular level. Visible RED light at a wavelength of 660nm penetrates tissue to a depth of about 8-10 mm. It is very beneficial in treating problems close to the surface of the skin such as wounds, cuts, scars, and treating infection. INFRARED light at 880nm penetrates to a depth of about 30-40 mm which makes it more effective for bones, joints and deep muscle problems.

Features

• DPL Therapy System Deep Penetrating Light For Pain Relief is for the treatment of pain, relief of muscle and joint aches.
• DPL Therapy LED Light Treatment is also used to relax muscles, the pain and stiffness associated with arthritis.
• The Deep penetrating light system uses a form of energy called Photons to penetrate deep into the body easing pain.
• Deep penetrating light LED therapy is a non-invasive, drug free therapy used for repairing damaged tissues.
• Absorbed energy from DPL LED light treatment is used to repair the tissue, reduce pain and restore normalcy to a otherwise impaired biological process.

Description

Recent improvements in LED technology have made them as ubiquitous as cell phones. In fact, LEDs light up almost all cell phones screens. The technology’s myriad applications and low energy use have made it nearly impossible to get through daily chores without coming in contact with LEDs. Probable advances include increased ability of the technology to support more efficient lighting and enhanced communications. With balanced coverage of the basics and future developments, Introduction to Light Emitting Diode Technology and Applications takes you on a tour of the LED evolution. The book begins with a brief history of the effort to enable the device that generates light through modern organic LEDs and reviews the fundamentals and principles of light prior to a detailed explanation of how LEDs generate different colors. After forming this basic foundation, the book examines the key LEDs in lighting and communications. It then discusses the latest opportunities and advancements in high brightness (HB) LED technology, solid state lighting, and handheld electronic applications. As we approach a new decade the role of LEDs is literally set to explode, with organic light emitting diodes emerging as a leading next generation technology for electronic displays and lighting. Challenges still exist, including light extraction, luminosity, and white light generation, not to mention non-technical obstacles such as IP disputes and the lack of standards. This book provides a foundation for resolving these issues and developing new applications for LEDs in the promising general illumination market.

Description

The world’s insatiable consumption of energy must be met with new technologies that offer alternative, environmentally conscious sources of light and power. The relatively young field of nonimaging optics is an ideal tool for designing optimized solar energy collectors and illumination optics and holds great promise in the development of solid state lighting applications. Introduction to Nonimaging Optics provides the first entry-level resource on this rapidly developing field. The book is divided into two sections: the first one deals with nonimaging optics—its main concepts and design methods. The second summarizes general concepts, including rays and wave fronts, reflection and refraction, and symmetry. The author makes a point to relate nonimaging to other popular fields, such as thermodynamics, radiometry, photometry radiation heat transfer and classical mechanics. He also provides useful examples at the end of each chapter. Introduction to Nonimaging optics invites newcomers to explore a growing field and delivers a comprehensive reference to those already working in optics, illumination engineering or solar energy collection and concentration.
