Hello srilakshmi

The CR4 Forum operates in the manner of most Forums.

A well-mannered question often gives a prompt and efficient answer, from our well researched Members and Readers.

Since you neither said 'please" or "thank you", perhaps you could use an Internet Search Engine, to look for your answer.

If you are genuine, and this is not a class or homework question, (We don't do those), please reply here, once more, with and re-phrase the Question, thank you.

Kind Regards....

Equal to the illumination produced by luminous flux of one lumen falling perpendicularly on a surface one meter square.

Now, I suppose you'll want someone to "Give formula for lumen" . . .

Why not just go the whole hog?

http://en.wikipedia.org/wiki/Lux

For years, lighting has been the ugly step-sister of architectural planning. Considerations of energy conservation have stimulated new interest in the field. If you're really serious about lighting, take a look at this page:

http://www.iesna.org/

It's the Illumination Engineering Society home page, with links to their excellent instructional materials.

It is in the books dear.

Spend time looking at those for your own development.
