Infrared project question - how to reduce illumination

[cornbuzzer]

I am looking for a way to add IR illumination to the inside of a birdhouse.  The little camera I bought can't see much in that darkness.

I am looking at the project "DIY Infrared Illuminator" (http://www.electronics-lab.com/blog/?p=5973).  I am afraid that this would be much too bright, so am wondering 2 things:  is there another project that I am not finding that isn't as bright, or is there an easy way to just use fewer LEDs in this project...  If the later is possible, I need help as my knowledge level doesn't go much past soldering...

So, in this particular project, can I just install 6 or 12 (instead of all 24) LEDs?  Do I then use just 2 or 4 of the resistors?  Where are they connected?  And what then do the power requirements change to?

Thanks in advance for your help.

Of course you can. Why would you think otherwise?

What do you think?
