Light Bulb Technology Comparison

With its ESL technology, Vu1 can produce light bulbs that have all the benefits of today’s energy efficient bulbs but add the distinct features that consumers and businesses want.

Energy Efficient– Vu1 bulbs are up to 60% more efficient than the incandescent bulb
Superior Light Quality – Unlike CFL or LED bulbs, ESL technology features qualities consumers enjoy now – a perfect light quality that turns on instantly and is fully dimmable
Mercury Free – Vu1 bulbs contain no mercury, allowing them to be household disposable and safe to recycle
Affordable – ESL technology adapts to existing light bulb shape, reducing production costs and providing consumers and businesses with a competitive and cost-effective solution
Smaller Carbon Footprint – Bulbs generated by ESL technology have a smaller carbon footprint throughout their lifecycles than those generated by LED and CFL technology
Lower Production Costs – ESL bulbs have lower manufacturing and disposal costs compared to LED and CFL bulbs

Electron Stimulated Luminescence^™ Lighting Technology

Light, Done Right

Vu1 has done what lighting innovators have tried for centuries to do – create a lightbulb that provides a pure, warm, natural glow at the work surface without excess heat, energy or harmful components. It's Electron Stimulated Luminescence (ESL) technology is thought to be the first bulb to approach the ideal of lighting reflectivity defined by scientist Johann Lambert more than 350 years ago. The Lambertian principles spoke of light quality that had a full spectrum of colors, and reflected evenly on the surface below. Today, Vu1 has developed a lightbulb that operates as a Lambert Radiator, meaning the light appears brighter than the Lumens would indicate approaching Lambertian perfection – to consumers it is simply a bulb generating more light, using less energy, and with a purer glow.

Overview

Electron Stimulated Luminescence™ (ESL) Lighting Technology is an entirely new, energy efficient lighting technology. It uses accelerated electrons to stimulate phosphor to create light, making the surface of the bulb “glow”. ESL technology creates the same light quality as an incandescent but is up to 70% more energy efficient, lasting up to 5 times longer than incandescent and contributing to the reduction of greenhouse gas emissions. There is no use of the neurotoxin Mercury (Hg) in the lighting process.

With this technology, Vu1 has developed its first light bulb that received UL certification in October 2010: the R30 ESL bulb is specifically designed to replace the 65W incandescent R30 flood bulb in recessed light fixtures and the light quality is virtually indistinguishable from this traditional lamp it replaces and, unlike CFLs, is mercury-free.

In addition to the R30, the company is currently developing a variety of highly energy efficient, optimal light quality mercury-free light bulbs. In 2011 and 2012, Vu1 plans to introduce the classic A-type lamp for US and European consumers, the R40 for the US commercial market and the R25 in Europe.

Proven & Safe

In creating ESL Technology, Vu1 merged several existing and proven technologies then uniquely adapted them for “lighting”. The company uses commonly sourced, non-hazardous, commercial materials that are customized to our specifications.

Safe as a lighting source, the ESL technology fits neatly into classic light bulb shapes similar to those familiar to consumers everywhere. This eliminates the need to bend the technology into an unusual, twisted spiral shape (CFL) or have costly and heavy heat dissipation designed into the bulb housing (LED).

Key features of the technology and associated manufacturing processes are patent pending.

Manufacturing

VU1 bulbs are manufactured in two facilities.

Sendio s.r.o., in the Czech Republic. This enables the company to manufacture its products directly to protect the company’s intellectual property while maintaining close control over the quality, volume and distribution of initial product production.
Huayi Lighting Company Limited was founded in 1986,and located in China Lighting Capital---GuZhen, ZhongShan City.After 20years development, insisting upon Quality and Profession management strategy, the company comes into one of the outstanding lighting manufacturers in the industry. As a result, the brandname of huayi has been recognized by more and more customers.

The company occupies 200,000 square meters industrial area, and owns 20,000 square meters of a modern showroom. With 26 workshops and nearly 1thousand monpoly stores domestically, Huayi is a modernized enterprise specialized in manufacturing and marketing of lighting, as well as engineering projects, real-estate, investment and international trade business.The sufficient investment fund on R&D allows the company constantly providing new lighting fixtures based on the stylish accent. During 20 years, cultivating, Huayi has not only provided more than 30,000 various lighting fixtures, but also built up a manufacturing chain through relative lighting products R&D, massive lighting bulbs, different parts produced to final products sales and distribution; precise marketing position ensures the successful biding on many project lightings from domestic market to overseas, including many five-star hotels, government office buildings, and prestigious residential lighting projects. In the new era, the sales of the company has increased rapidly. Billions of turnover each year enables the company to be the top-rank and lead the lighting industry.
