When our users want to simulate blacklight, our color 181 is the most popular choice. There are a few caveats:
181 is not equivalent to blacklight. Blacklights create their effect by the UV light present in the lamp. 181 cannot "add" UV to your light bulb. Only a blacklight lamp can truly create that effect.

Depending on the wattage of your lights, and the distance from the filter, fading could occur very quickly. We have no way to estimate how the filter will work with your lights. Test it in advance and closely monitor it in case there is melting due to high temperatures. If what you are trying to achieve is a temporary lighting effect similar to blacklight, 181 may work. If you are looking for a way to create blacklight on a regular basis, you will need to install blacklight lamps.
