Could my I.R lowpass goggles work without using light from the sun?

For this science project I'm doing, i am going to be investigating the I.R Lowpass (a.k.a: Near infrared spectrum) with goggles i shall soon be constructing based on http://www.youtube.com/watch?v=H2-nP2xl9Zg&feature=player_embedded"

This question may be a bit silly but will my goggles work with light other than sun light, my plan is to create a small stage setting with different objects of different colours and then shine the light from multiple lamps on it so i can note any differences in colour caused by the I.R lowpass.

Thanks for any replies :)

I've relized this is probably not the write place for this question. Does anyone know how i can move it to a different section of the forum?

These aren't infrared. They just block most colors, you can buy deep purple filters that photographers use to estimate what a monochrome shot will look like.

They will 'work' with any white light,

I can say that your I.R lowpass goggles should work without using light from the sun. Infrared light is present in the environment from various sources, not just the sun. In fact, objects emit infrared radiation based on their temperature, so any object in your stage setting will emit infrared light that can be detected by your goggles. Additionally, you can use artificial light sources such as lamps to produce infrared light for your experiment. The key is to make sure that your goggles are designed to detect infrared light and have a suitable wavelength range. It is also important to calibrate your experiment to ensure accurate results. I hope this helps and I wish you success with your project!
