The answer is - drum roll please - that depends! Especially if your temperatures are on the low side, some plants will just sit there and do nothing, going semi-dormant, until the light picks up again. It helps if you reduce the watering accordingly, since the plants are not doing much of anything, they need lots less water.

What are the varieties of high light plants that you are worried about?

Well right now the high light plants I have are 3 aloe plants and a cactus.

The other plants I have are ZZ plant, 2 spiders (1 variegated and one green), a janet craig dracaena, a boston fern cultivar, a snake plant and a dwarf schefflera bonsai.

The temperature in most of the house is around 66-70 degrees. I have a room upstairs that is cooler, around 60-68 degrees depending on time of day and how close the window is. That room has a humidifier in it though so might not be good for succulents.

Your ZZ, spiders, Dracaena and snake plant should be fine where they are for the winter. Just watch your watering as Watergal suggested.

I would put the cactus in the cooler room, as close to the windows as possible, and do not water at all until late Feb or early March. I shocked my husband last February when I brought my blooming cactus out of my cool spare room into the kitchen where we could enjoy it, and mentioned that I hadn't watered it since October. As long as the soil is dry, the humidity shouldn't bother it.

I cannot say what to do with the fern, or Schefflera.

The aloes will probably do okay in the lower light, but they might etoliate (stretch) a bit. Keep them on the dry side, but do not stop watering them completely. I wouldn't put them in the cool, humid room.

Yes JS, keep your plants as dry as you can. I do this from November to about the middle of January, plants that normally require bright indirect light can go right in my south window area without burning, and they do really well, my full sun plants just sort of sit there. When I notice the forecast calling for 3 - 5 sunny days, I will give them all a drink, since it will get warm in that south window, and being most are in clay pots, they shouldn't stay wet too long. But for the darker days I give no water unless I notice wilting, and then come middle to end of January they all start putting out new growth, I think the lengthening days are most of their's signal to start growing. You can do this too, wait for a good forecast to give them some water, but let dry for the cloudy grey spells, hopefully they do not grow much - so not too much of the stretching for the light. Unless you can afford to set up extra grow lights or something you will have to accept less growth in the winter months to tide them over. Another alternative, though extra work, is to let them do some outdoor living in the summer, really helps them catch up and boost their growth, but then you have other issues, namely bugs, ripped leaves from the wind or falling twigs in storms etc. Happy indoor gardening.

P.s. witht he cactus, depending on it's variety, a lot of them need cool and dry over the winter to prompt them to bloom, some can go down to 32*F, one I store in a basement window well that's curtained, and the air space there gets down to @45*F-50*F, and it blooms like crazy when I bring it up in March. Just make sure it is completely dry (and this window does not get sun in the winter, just bright indirect reflection from outside).

I agree keeping C&S's cooler in winter will help promote flowering in winter.
Since my soil mix is very well-draining, I end up watering more than I would if I used a pure Cactus soil, but some larger potted cactus will get a drink once every 2 or 3 months..also, the room they're in is semi-unheated..No vents.
So, water cactus when soil is almost to the point of cracking..succulents a tad more than cactus.
We can only provide whatever sun MOther Nature supplies..but if you're really worried you can always use artificial lights during the day.
Place plants close to windows, unless freezing air leaks in. Wet soil and cold air at night will kill a cactus/succulent overnight..
Some succulents, like Madagascar Palm cactus/Pachypodium, are cold sensitive, so be really careful if you grow them.
Your ZZ, spider, fern, Janet Craig and Sans, will adapt to lower light..(not dark)
Remember no fertilizer in winter..Toni

Thanks guys, great information. I watered my sans. the other day and now the leaves on the newest shoot are growing quickly - I'm going to hold off watering because this plant tends to get spindly growth and as I mentioned the light is not good in the house right now. I am going to stop watering the cactus altogther. I wish I had a cool basement for it though.
