All I can add is the use of door mirrors sold for around $4 each. I use them on both sides of the lights. One side with holes on S hooks so I can remove it to look at my plants. I also use an old 55 gallon fish tank. With only one 4 foot twin bulb T5's on top. It is enough for wintering my Sans. collection of smaller plants. Also for Haworthias and most small Aloes.
