Dear Mr. Bhanot
This is not a lamp and neither does it generate light.
The same result can be achieved by using bits of
semi translucent fibre glass sheet regularly.spaced
to let in sun-light through the shanty GI or asbestos roofs.
To summarise:
1) This "lamp" is only acting as a lens for the sun
2) The bleach is to prevent buildup of microorganisms
3) There is no chemical reaction taking place whatsoever.
