Bp's are nocturnal creatures, so it will probably have a negative effect on your bp. You can get a red light (a true red bulb, not a party bulb) and put that in the enclosure instead if you want to run it all day and all night. Otherwise, I suggest you get a electronic timer (I don't know where you can find one in malaysia). that you can plug the light into so it will turn itself off and on automatically.

I know that Zoomed makes a red light basking bulb. The theory is that repiles can't see the wavelength, and so it has no effect. I use one the red light bulbs myself (to provide more heat). My bp always comes out of his hide and night and wanders around in his cage.
