The shoplight fixtures
are the reflectors. The in-store brand is called "Commercial Electric", believe, and they sell one locally that costs $7.99 (and holds two T8 or two T12 bulbs. You can pay more and get a much better one, but this one does have the all-important electronic ballast (which is much better than a magnetic or 'tar' ballast that T12 shoplights usually use.
All T8, 48" bulbs are 32W as far as i know.
The brand of the bulbs themselves isn't important, but my HD sells the Philips ALTO line, which have green endcaps. I like these because they are very efficient and non-polluting, and if you get the one called the TL850 or TL750 or even TL741 it will be a nice color temperature and good spectrum. Last time i went they were half the price (around $2) they were when i first got some six months ago, and they had two models instead of one, so i think they're getting more popular/common.
If you care to know, in the ALTO line, the L in the model number stands for "linear", the 7 (or 8, etc) stands for the CRI (7 represents ~75, 8 is ~85), and the last two digits for the color temperature (41 is 4100K). Hence, what i have are linear bulbs with a CRI of 75 and a color temperature of 4100K. I wouldn't recommend getting anything lower than the 41 if you can help it - that ends up being a bit "red".
Hope that was helpful. If you search around, i believe i spouted all sorts of opinion mixed with fact on this subject in various threads.
I have my VFTs from 6" to about 4" below, but you could probably put them even closer. Experiment, and let us know how it goes. Just remember it takes some time for the plant to adjust, and even more time for it to respond favorably if it likes the new conditions.
Finally, if you have a sunny window, that's the best lighting of all for them. My VFT got along famously in my southern window in SLC (even with large eaves), where elevation makes the sunlight more intense. Even S. minor did well there. Here in Boston it doesn't do so well. Probably doesn't help that we haven't seen the sun for what seems like a month.
