iirc from your other post, you brought her home recently so she's still settling in. Also, don't let bp hissing put you off. My biggest bp is a "tub hisser", he hisses when I reach into his tub to pick him up but once he's in my hands he's fine. I never let my bps hissing deter me from picking them up. I'd rather they learn that nothings going to happen and hissing doesn't get them anything.

She's in a tank right? You need to up the humidity, the lightbulb won't be any better than the CHE and will likely stress her out more because of the light. Get moss, cypress mulch, or some other humid substrate and put some in her tank. Cover the top of the tank with tinfoil or a sheet of plastic. Do you have a hygrometer?
