Since it appears to be using BL bulbs instead of the BLB bulbs (BLB tubes has a visual light filter), it will put out light in the spectrum required for silver gelatin papers for exposure...thus it should work for your Ilford contact paper. I believe I have read that Azo paper, another contact paper, does benefit from the extra UV. But I am willing to be corrected on this.

It will not work very well with VC paper if one wishes to be able to adjust contrast. But as Jim suggested, it will also be nice for making small platinum, cyanotype and other alt process prints.

Let us know how it works for you!
