ARUN JAIN'S DIARY

I was curious to know how much a family used to pay before the invention of electricity in the late 19th century.

A few data points which will help you connect the economics of light that we have been enjoying in the last 125 years.

1. One oil lamp consumes 15 ML of oil per hour.
2. One oil lamp lumen is around 10 lumens.
20 oil lamps for 4 hours per day for lighting a basic house requires 1.2 litre of oil every day or 36 litres of oil per month.
3. Cost of lamp oil per litre is around 180 rupees.
4. Thus the oil bill per month with just 200 lumens of light at home for a month will cost 6000 rupees.
5. Oil was not cheap in the olden days thus it used to form a substantial part of the family expenses.
6. The design of chandeliers was to increase the total lumen in a hall by aggregating 30-100 oil lamps.

Some more data:
1. A 20 watt LED has 1600 lumens equivalent to 160 oil lamps.
2. 160 oil lamps will consume 2.4 litres of oil per hour at 180 rupees which equals to 432 rupees per hour.
3. A 1000 watts per hour (1kwh) of electricity costs less than 10 rupees and 20 watts will cost 20 paisa.

Now you connect the dots and get your imagination to work.

For our global friends, we celebrate Diwali in all Indian states, but for different reasons. In North India, Diwali symbolises Lord Ram’s return to Ayodhya, while in some other parts of the North, it celebrates Mahaveer’s achievement of Nirvana. In this way, Diwali means something different to each member of our community.

In the 30 days leading up to Diwali and the 3 days following the same, India is met with an unmatched festive spirit. During this period, Navratri, Dussehra, Ayudha Pooja and Durga Pooja are celebrated for 8 to 10 days all across India.

We celebrate our three powers through three goddesses:
1. Physical Power represented by Kali or Durga
2. Knowledge Power represented by Saraswati
3. Economic Power represented by Lakshmi.

With the festival of Diwali, we celebrate Goddess Lakshmi who represents economic power, by decorating and lighting up our houses to invite her into them. We invite Lakshmi into our homes, to fill them with prosperity and knowledge, and to monetise all our knowledge power.
