Energy Efficient LED Lights
 What is LED Light
 LED light is the most common abbreviation of LED Emitting Diodes ,
also known as a Solid State Lighting that Emits light When a voltage applied
to it .
 A high Power ,high –efficiency technology created with non-toxic
materials
 Solid –state, high shock & vibration resistance
 Up to 80% energy saving results in major reduction of electricity
consumption bills
 Long Lifetime up to 50,000 + hrs
 No UV radiation

Energy Efficient LED Lights
Benefits of LED lights

 Minimal Power consumption : Saves energy on average 60 to 90 % over conventional
lighting depending on type of light.
 Average of 40,000 hours of life span :Unlike CFL ,halogen,MH and incandescent last a
long time with out any bulb changing saving maintenance cost .
 Does not contain Mercury : It does not contain harmful gas that affects the ozone
 Does not operates at high frequency : Works at low DC voltages and does not harm
human body
 Increase visual Acuity : Pure white light close to daylight ,excellent visual acuity for
CCTV
 Instant On : Instant lighting within 100ns ,perfect for motion sensors/saving energy
when not in use
 Dimming capability : It can be dimmed with a new patented technology
 Perfect color : Allows for full variation of colors
 No wastage :Reduce wastage (Long working life )
 Reduce air condition load : less heat produced than conventional lighting
 Stylish : LED lights are more stylish
 CO2 foot print :Reduces indirectly CO2 Emissions
 Green : It is absolutely GREEN

Energy Efficient LED Lights
Saving in Air-conditioning system
 Surface heat produced is 20% of conventional Spot light
thus saving on air-condition system.
 Heat created from LEDS light is in the opposite direction
compared to conventional lights. Therefore heat is dispersed
with the return air instead of the user environment .

Energy Efficient LED Lights
 Kwh Saving if Kuwait switch to LED lights
 Kuwait total Electricity power Consumption is above 13,000 MW
 Assuming in Kuwait on yearly average the lighting use is 30 % of
Electricity consumption , therefore 3900 mw used for lighting
 Assuming Average saving of power consumption about 70% if we use LED
 The lighting consumption drops to 1170 MW
 Assuming we reach 50% LED and 50% conventional light ,therefore
lighting Power consumption will drop to only 2535 MW only.
 With a saving of 3900 minus 2535 = 1365 MW
 This is equivalent to a capacity of one New Mega Power Station

Carbon Dioxide Foot Print
 The US average is 1.34 lbs. of carbon dioxide per kilowatt-hour, from the
US Department of Energy.
 For example: a typical LED 9 watt LED bulb replaces a 60 watt
incandescent and lasts 50,000 hours. The savings of 51 watts times 50,000
hours equals 2,550 Kwh. At 1.34 lbs. of carbon dioxide per Kwh the savings
is 3417 lbs. of carbon dioxide that is averted from being released into the
atmosphere.

 LED Light usages in The GCC
 Dubai is head of all GCC
 Others are in between
 Kuwait is the lager of the group
12
Energy Efficient LED Lights
Type of LED lights
LED Lights ranges now cover a wide range of uses
Indoor Light
Outdoor Light
Commercial Light
Industrial Light
13
Energy Efficient LED Lights
Incentive to switch to LED
 Initial investment in LED lighting is much higher than
conventional Incandescent or CFL light
 However long term ownership is cheaper to the owner
( household, industrial, commercial )
 How to convince people and establishments to switch
 Laws and regulations that gradually limit or abandon the use of CFL
initially due to environmental hazardous ( it contains mercury ) and
Incandescent and other types of lights for certain uses such as large
establishments , malls , industrial ( large consumers )
 Increase people awareness of environmental , health and energy
saving at large both individuals and institutions .
 Some sorts of incentives if applicable .
14
Energy Efficient LED Lights

LED light represent the future of a new generation if ecofriendly ,Long lasting lighting system.
 LED lighting is poised to make conventional light bulbs and
other type of lights obsolete offering higher energy efficiency
,Long service life and much lower environmental impact
