Blacklight options for playroom?

Does that heat up at all? Like I said, we're looking for portable and something we can just set somewhere and plug it in. Thanks!

We would like to play with UV reactive paraffin candles, but want to make sure whatever blacklight we go with is both simple/portable and can just plug and play rather than needing to be mounted and will be effective for really lighting up the candle wax on whoever is tied to the bed. Anyone have experience/success with such an item? Thanks!
