Vu1 Brings a New Light with Electron Stimulated Luminescene

Electron Stimulated Luminescence™ Lighting Technology

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, a direct replacement for the 65W incandescent flood bulb which 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 operates a wholly-owned manufacturing subsidiary, 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.

The 75,000 square foot facility provides Vu1 with scalable production capability. The site’s initial production capacity is up to 6.8 million bulbs annually with a planned future capacity of 30 million bulbs annually. Vu1 employs a highly skilled team that has been trained at leading manufacturers such as Philips and Sony. The facility is centrally located, enabling efficient worldwide distribution.

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 70% 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
• All of Vu1’s bulbs will be UL approved and in the future ENERGY STAR® compliant.
• 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
