1 The Company

e.Energy Lighting Ltd. (e.Energy) was founded in 2006 with the support of CityU Enterprise Ltd. and

private investors.

The Company aspires to be GLOBALLY RECOGNIZED by offering the MOST INNOVATIVE /

EFFECTIVE and UNIQUE ENERGY SAVING & GREEN technology in the Lighting Industry.

Through the integration of our expertise in power electronics, lighting science, information systems and

communication networking, the Company offers patented “green and sustainable” solutions for energy

saving and management capabilities in large-scale (both indoor and outdoor) lighting systems. In

particular, the Company provides green technology that not only reduces power consumption but also

electronic waste arising from commonly-used electronic ballasts.

The award winning technical team behind the technology has won the recognition of:

(1) Two Hong Kong Awards for Industry

i) Technological Achievement Award in 2001

ii) The Consumer Product Design Award in 2004

(2) The Notable Mention Award in the Hong Kong Eco-Products Award 2006

(3) “Best New Product 2005” Award from Australian Electrical and Electronic Manufacturers

Association

e.Energy has developed technology and products that not only reduce power consumption (i.e.

reduction of greenhouse gases), but are also compatible with recyclable low-loss magnetic ballasts that

can last for more than 30 years (i.e. reduction of electronic waste arising from electronic ballasts that

can last typically for 5 years). Our green energy saving technology has been scientifically proven to

provide dimming to lighting systems with magnetic ballast with successful installation since 2003. It

has gone through vigorous professional peer-reviewed and published in the prestigious IEEE

Transactions on Industrial Electronics 1 (Dec. 2007). What is more, our green energy saving technology

1 A non-profit organization, IEEE is the world's leading professional association for the advancement of technology. The IEEE name was

originally an acronym for the Institute of Electrical and Electronics Engineers, Inc. Today, the organization's scope of interest

has expanded into so many related fields, that it is simply referred to by the letters I-E-E-E (pronounced Eye-triple-E).

One of its journal, IEEE Transactions on Industrial Electronics is published monthly. Its scope encompasses the applications of electronics,

controls and communications, instrumentation and computational intelligence for the enhancement of industrial and manufacturing

systems and processes.

is compatible with both magnetic ballasts and electronic ballasts making them highly flexible in their

implementation.

2 The Product

T&K Lighting Management system (T&K

LMS, ‘The Product’) - the patented technology

developed by the Company – can substantially

reduce the electricity bill by 20% at least and

at the same time turn most of the existing

“non-dimmable” lighting systems into

“dimmable” ones without major change in

wiring and infrastructure. Customers are

provided with a new freedom of control to use

lighting energy when and where necessary and

at an appropriate level.

The product supports ;

10A, 20A, 32A

60A/110A ( target in 2010 )

LMS

Apart from reducing the consumption of electricity, the Product includes highly energy-efficient and

programmable Central Dimming System for existing and new lighting systems including, but not

limited to, the following applications:

2.1 Achievable Saving Table T&K Lighting Management System is suitable for indoor and outdoor lighting. It is compatible with a

wide variety of lamps, such as high and low pressure sodium, mercury vapour high pressure, fluorescent

low pressure lamps and compact fluorescent lamps. The maximum achievable power saving of each

lamp type with our system is tabulated below:

Lamp type T&K LMS achievable power saving* [%]

Fluorescent lamps with magnetic ballasts 18% - 25%

Fluorescent lamps with electronic ballasts 20%

Mercury vapor high pressure lamps 30%

Energy saving lamps (low power) 18% - 30%

Metal halide lamps 30%

High-pressure sodium lamps 40%

Note: The actual saving is largely dependent on the ballast and lamp characteristics.

3 Competition Analysis

Direct competition using same technology:

There is no direct competition because this is a patented technology. There is no existing technology

that has the same features of energy saving, reduction of electronic waste and smooth dimming

performance in the market.

Competition using other technologies:

Transformers have been used in the lighting market for energy saving. However, they are inferior to

e.Energy technology in terms of performance, cost and flexibility as shown in the following table.

T&K LMS Transformer

Principle Modern Power Electronics Electromagnetic

Voltage settings Continuous Discrete

Smooth dimming Easy No

Flexibility in power control High Low

Noticeable change of light No Obvious (Extinction of lamp arc)

Maximum loss 1%-2% of full power

(Typically)

5%-10% of full power

(Typically)

Adverse effects on lamps No Yes

Regulated output voltage Yes No

Another technology is the use of dimmable electronic ballasts. But such technology is inferior to

e.Energy products in terms of costs, lifetime and robustness against extreme weather conditions as

shown in the following table.
