Yeah. Likely your christmas lights are incandescents. These are pretty much the worst light bulbs we could have invented. They use a lot of power inefficiently.

This means, you'll have a lot of unwanted heat.

Even worse, likely the light produced won't be within the useful range for your corals.

If you had other lights to supplement, then I see no problem with it (other than heat).
