you will go broke buying those "daylight" bulbs from the pet store. take yourself down to walmart or home depot and get 4 soft white bulbs for 75 cents. they're the best. lol. I use blacklights on mine all the time, for a few reasons. When I first got my first snake, i tried the white light during the day and a blacklight at night. This quickly came to an end. one is that 2 fixtures for one tank was one too many. and i wasnt going to burn my hand every night to change a danged bulb. But also, they seemed to be scared by the bright white light. Honestly, wouldn't you be scared if you came out of a cave and were blinded by a big bright white light coming from the sky? lol.
Now I keep them under a blacklight bulb 24/7. I have a 60 watt in my 29 gallon, and a 60 watt in my 20 long, however I went down to home depot and bought a table lamp dimmer to cut it down halfway. Works great.
Have fun on your trip! you're probably already gone! lol.
