Does light have an effect on the growth of bread mold?

So I just recently did a science fair project. I used four light bulbs, 15, 40, 75, and 100 and I used wonder bread. I have completed the project and now I have to do the research paper. From my results, it turned out that the bread with the smallest watt was the watt that molded the fastest. I have been searching for outside data from other people who have done the project. Would help me find a link that could help me with my research paper or if you have some knowledge on why the dimmest light molded the fastest? Thanks

The rate limiting factors to fungal growth are moisture, temperature and food. You will have varied both warmth and moisture.

Mold needs between 40 - 100F temperature to grow. What were the temperatures under each bulb?
Mold prefers the moisture content to be about 70% for optimal growth. Fresh breads are only about 40% so do not offer an optimal growth medium but it is still wet enough. (Some companies have published their typical moisture contents - white bread 36%, Oat bran bread 44% and canned Boston brown bread 47% - these will not be true for all bread but it gives a rough beginning range of 35 to 45%) If moisture drops below 10% mold is very unlikely to begin or continue. . This is why crackers can keep but bread cannot.
