We’ve always had a slight problem with light bulbs in the livingroom, but recently the problem seems to be getting worse.
We were rewired last year so ther are no problems with the wiring and the light fixture is fairly new . Please help I am sick of changing light bulbs.

I just had a question in school about designing an experiment to measure the effect of light intensity on the number of stomata.
My question is only about controlling light intensities…

1. Should I use the same lamp but put it different distances away from the plant?

2. Should I use light bulbs with different values for power?
