CFLs are toxic !• Compact fluorescents, like their tubular fluorescent precursors,

contain a small amount of mercury—typically around five milligrams. Mercury is essential to a fluorescent bulb's ability to emit light; no other element has proved as efficient.

As effective as it is at enabling white light, however, mercury—sometimes called quicksilver—is also highly toxic. It is especially harmful to the brains of both fetuses and children. That's why officials have curtailed or banned its use in applications from thermometers to automotive and thermostat switches. (A single thermostat switch, still common in many homes, may contain 3,000 milligrams of mercury, or as much as 600 compact fluorescents.)

• Estimated at USD 73.3 Million in2010

• Expected to reach USD 470Million by 2015

• Street Lighting to account forapproximately 60% of the LEDmarket in 2015

• Higher acceptability by theGovernment and energyefficiency will be a crucialsuccess factor for quick adoption

Indian LED Lighting market estimated to growat >40% till 2015!

Growth Drivers

• Investment by the government in energy

efficient lighting systems

• Decline in the average prices of LEDs

• Quick RoI to drive adoption

• Improvement in technology addressing new

applications

• Global mandate to arrest global warming and

migration to technologies like LED

13Source: Frost and Sullivan report 2010

Energy efficiency is the top driver

• Lighting consumes 17% of the total energy

• More than 80% of current lighting used is based upon antiquatedtechnology

• Use of more efficient LED technology will not only save energy but alsolead to reduction in the emission of greenhouse gases

14

Lumen/pack and lumen/rupee driving penetration

• Lumen/pack has doubled consistently every 18 months for the last 30years

• As lumen/pack increases, more and more applications becomemeaningful

• Overall LED penetration in India is low but gaining momentum rapidly incertain applications eg. down lighting, accent lighting and to a certainextent in low wattage street lighting

15

Government encouraging energy efficientprocurement - a key driver of LED penetration

•

•

•

•

•

Pilot projects started in some states

Some tenders for low wattage street LED street lighting awarded

Lack of proper standards can lead to concerns about reliability

Standardization activity already started at BIS

BEE guidelines in circulation

16

Meaningful LED solutions for Home Lighting

• LED lamp designed and manufactured in India launched in 25, 40 & 60watt equivalents

• LED Home Decorative Lighting range launched

17

Meaningful LED solutions in Office & Retail Lighting

• Remote phosphor LED down lights which offer 50% energy savingwhen compared with CFL down lights

• LED accent lighting solutions which offer 80% energy saving whencompared to halogen spotlights

• Light quality comparable and attractive TCO

• Good momentum seen in offices, retail and hospitality

18

Meaningful LED solutions in Outdoor Lighting

• Low wattage street lighting LED solutions designed and developed inIndia launched for A2, B1 and B2 category roads

• Some momentum already seen though many customers are stilltentative when committing

• Inability to differentiate between good and bad solutions is the majordeterrent. Availability of standards is key

• High wattage street lighting LED solutions available in global ranges …however need higher customer commitment before taking a decision onlocalization

• LED city beautification range

19

Meaningful LED SOLAR streetlighting solutions

• Locally designed and developed solutions for off-gridand on-grid applications launched

• Solution specifically developed for MNREspecifications also launched

• Key applications in rural as well as secondary urbanroads, industrial complexes and townships

20

Support required from the Government

• Implement recommendations of “The Economic Case to stimulate LED Lighting in India” white

paper issued by the Ministry of Power

• Drive standards

• Create environment for manufacturers to invest in production of LED chips in India:

– Offer land at subsidized rates; government funding participation; soft loans; tax holidays

• Bring in notifications:

– All showrooms or show windows using Incandescent Lamp or halogen lamps to replace

them with LED down lighters

– Mandatory use of LED streetlights for secondary roads, parks and parking areas etc.

• Government bulk procurement

– Preparing bulk requirement of Railways, Airport authority, Urban Housing, Highways &

other large development projects to create a large demand to encourage the industry to

expand

• Test Labs

– Government subsidizing establishment of LED test facilities at existing Test Lab (~ Rs. 25

Crores)

– Need higher investment for many more Test Labs

22

Fixture Options

• Fixtures for many applications including architectural, hospitality displays and much more

• Effects-based lighting such as RGB Intelligent Solid-State Illumination. Networked and easily controllable

• White Solid-State Illumination• Control options & power supplies selected

based on application
