Post by deleted-303657 »

In the science experiment it says that you are supposed to leave the daylight blue 100 watt lamp pointing to the water for 12 hours.I have a daylight blue 150 watt lamp how long am i supposed to leave this one pointing to the water.

I need help ASAP my science fair deadline is ending soon.

Hi Julian,

100/150 x 12 = 8

So instead of 12 hours with a 100W lamp you would use 8 hours with a 150W lamp to get the same total light exposure.

Any other questions?
