Dont trim the fan leaves. Your fan leaves act as a storage center for mobile nutrients(NPK) that the plant builds so it can draw on those reserves during flowering. During late flowing the fan leaves show signs of extream nute deficiency as the plant drains them of nutrition, eventually leaving a light brown wringled mass.
Removing these leaves denies the plant this nutrient buffer and as a result production can suffer. Sometimes common sense moves like cutting fan leaves to promote light penetration can back fire, look at both the good and the bad parts of it. Trimming fan leaves, unless you are really really aware of what your doing as far as plant nutrition can hurt more then it helps.
Yo, cheap CFL reflector, get a file and scissors or tinsnips or a hacksaw and split an aluminum can, the inside is highly reflective and perfectly sized for a 43~watt cfl
