I've been trying to choose only cacti that will do well with less light, since I have only an east-facing window to put them in. Most of them seem to be doing well, but some of them (a couple of the ones I got before I knew what I was doing or where to find light requirements) seem like they could use a couple more hours of light than they get in the mornings.
I'm not looking for anything super fancy, just something clip-on that I can move between shelves to give them each an extra hour or two of light (I have a baker's rack with wire shelving that they are set up on right now). Would something like this work, if I got two of them? http://smile.amazon.com/Hydrofarm-LKIT6 ... lant+light" onclick="window.open(this.href);return false;
Or is there something better (but still fairly cheap) out there?

Re: Lighting questions
Those kinds of lights tend to give out too much heat and infrared radiation and can worsen the problem. Using fluorescent lights is a much better idea in my opinion. You can use CFLs or tubes if you like and 'cool white' seems like the best kind of bulb to use.

Thank you very much! I will narrow my search a bit.
Re: Lighting questions
There is an article on lighting on this web site:-

Re: Lighting questions
I'm having problems finding fluorescent tubes that would clip on to a wire rack, and I just don't have the space for a big hydroponics-type set-up. My ceilings are too high to install a tube above my cactus rack, and I think that would violate my lease anyway, lol.
I know the article says CFL bulbs are less efficient, but since my plants are getting direct light in the mornings and indirect light all day, do you think I could get CFL bulbs and clip-on fixtures like this: http://smile.amazon.com/Woods-0151-8-5- ... R01YQJYJ00" onclick="window.open(this.href);return false; ?
Sorry if I'm asking stupid questions, I just want to make sure I'm not going to be wasting money on something that won't work. I really just want to get some more light onto the backs of the plants (I do rotate, but I don't feel like it's enough) and compensate a little for the lower afternoon light. I'm not looking for anything major, I only have 15 cacti, and with three exceptions they are all ones that do well in light shade or partial sunlight, according to the Internet.

Re: Lighting questions
A CFL with that fixture would work nicely in my opinion. CFLs are best for illuminating smaller spaces. Tubes are better for larger areas. An alternative to hanging a tube fitting from the ceiling would be to make a shelf above the plants and affix the light fixture to that, but that's probably a bit excessive for your setup. The CFL should work nicely.

Perfect, thank you so much for the help and advice!
