For a BP you want the T8 enclosure; I don't think there's an option for a ledge with this one, but that's unnecessary for a BP. Depending on your needs get the divider. If you want heat tape, it's cheaper to order some and do it yourself. I have the sliding glass door option and have seen others recommend the same. Lights are a nice feature - they have an LED option not on their website. You can also have them machine in the groove and order/install lights for cheaper.
