Is the owner of a house entitled to access of the full quantity of light over the adjoining house which he has enjoyed for 20 years in India?
He does not obtain by his easement a right to all the light he has enjoyed. He obtain a right to so much of it as will suffice for the ordinary purposes of inhabitancy or business according to the ordinary notions of mankind, having regard to the locality and surroundings.
Where there has been an interference with ancient lights, no action can be maintained unless the comfort and convenience of dominant premises have been affected considering their nature and locality, and the amount of light still left.
The only amount of light for a house which can be claimed by prescription of by length of time without an actual grant is such an amount as is reasonably necessary for the convenient and comfortable habitation of the house.
