Is there anything other than sunlight i can use to see with my goggles?

The riddler

Greetings,

I have successfully made goggles that show the I.R lowpass (Near infrared spectrum) based on this video: http://www.youtube.com/watch?v=H2-nP2xl9Zg

They work well in sunlight but they don't work at all under normal light bulbs. I was wondering if they is any sort of artificial light source i could use that would have the same affect as the sun does on these goggles.

Thanks for any replies :)
