Ok, so I know everyone here looooves them some MVB. Today marked the start of my building project. I'm beyond thrilled. I was on reptileluv.com looking at the different bulbs and things there. Today at the Reptile House, while build f/t pinkies for my new corn that's comming soon (yay), I saw they had similar bulbs by ZooMed and T-Rex. Those too provided UVA and UVB... Now, how would you guys compare the products? Also... my CWD tank is going to be 4 feet long, 4 feet tall, and 2 feet deep. the beardie tank is going to be 4 feet long, 1.5 feet tall, and 2 feet deep. Would one bulb be enough to heat both enclosures? I'm a bit worried about the WD enclosure seeing as it's going to be quite a bit bigger.. any suggestions? Any wattage suggestions? These are not cheap bulbs so I don't want to screw up here.
