    As you all know the energy sources now we are using is going to vanish between some 50-60 years. in India the state of this disaster is very high because a 60% of total energy is produced by thermal plants which uses coal as a fuel.the coal which is required about thousand kilos a day will make it disappear between years. the chances of bringing a nuclear power stations will be very low. before some months a new project was suspended by government on koodamkulam. every houses and industries are responsible for this.

    Major part of the energy can be save if we replace the illumination techniques by using LED lightings. I am in part of technical marketing of LED lightings manufactured by our firm.so in my experience i can add-on some details about LED lightings below.

    Compared type/light source





    Power consumption required for same lumens





    (65 Days*20 Hrs) * 10 Yrs
    Total Hrs 36500

    Power consumption per hour


    0.125 kwh

    0.2 kwh

    0.06 kwh

    Typical power consumption for one year


    456.25 kwh

    730 kwh

    219 kwh

    Electric charge for 1 yr

    6387.5 units

    3193.7 units

    5110 units

    1533 units

    Electric charge for 10 year

    63875 units

    31937.5 units

    51100 units

    15330 units

    Service life (hour)




    Above 40000

    Replace times for 10 years

    36 times

    12 times

    12 times

    No need to replace

    Expected consumption

    Electric charge + (cost of light source )(replace times) +(labor or replacement)(replace times)


    Well, I don’t think electricity is in any danger of disappearing any time soon.  The fuel sources (required to make the electricity) are likely to change a few times over the next century or two. 

    LED’s are most likely to be the future for all lighting soon enough.  The only thing holding them back now is price and assembly costs.  But that will be better once the automation is put to work.

    I must say, I’m not sure what kind of lighting you mean by “GLS” or “FTL”.  Not all of us use these terms as often as you might because you are in a particular segment of business.  If by FTL you are referring to “fluorescent tube linear” your numbers may be too general to make a valid comparison.  Perhaps you have been talking to the marketing folks a little too much.

    Lighting has frequently been too complex of a subject for many people to understand.  By that I mean that terms such as CRI (color rendering index) really does not compute for most people.  But it can be extremely important in some situations.  Other terms have been generated due to technical issues with respect to getting the best response for your device (or lamp) and most people really don’t care.  In fact, if it turns ON then that is generally all they want to know.  If it doesn’t look like enough light, they get a bigger bulb.  That is about all that most people (>90%) really care about.  As to how much it will save, … there is always tomorrow to pay for it.  It just needs to work when it is turned on!
