You can throw them under a grow light in that case. I would recommend an LED light, since it wont drive the temperature up as high as a T5 fluorescent. You want it down in the 40s if possible. Amazon has good, relatively cheap LED bulbs here: https://smile.amazon.com/gp/product/B0196JMJ36/
Here is an in depth article on lighting carnivorous plants, if you want to get into the technical details: http://www.carnivorousplants.org/howto/SoilsWater/Lighting.php
Cacti need a lot of light. Like, a lot a lot. Outdoor direct sunlight is 100,000+ lux of full spectrum. 1 lux = 1 lumen at 1 meter. I usually derate bulb specifications by 50% when estimating. A bulb that advertises 500 lumen would be 500 lux at 1m, derated by 50% would be 250 lux, or 0.25% of outdoor light.
Here is an 80W LED bulb but I doubt that lamp is rated for this. That bulb is ~4500 lumen, so let's say 2000 lux of usable light at 1m. Placing the bulb very close to the cactus will greatly increase the lux, so I bet you'd get 20,000-30,000 of lux out of that if it's very close (and depending on breed, a cactus will probably enjoy the heat).
