Alright ... so, I bough the ReptiSun compact, and as I understand it, they need to be replaced every 2 months because they're the compact ones? Maybe I'm not remembering right. IDK. I've also heard that the compact ones aren't that great. I also got the spiral compact one instead of the tube compact, because the store only had the spiral 10.0 in stock. I mostly got the compact one because I started my CWD (only has 3 legs) in a small-ish set up (13g). He's currently (it's been roughly 3 months, maybe less since we got him) in a 90g, so I could put a tube in there now. Does the wattage on tubes make much of a difference? Even the Arcadia bulbs have a wattage listed on them. I'll probably stick with ReptiSun until we get his adult enclosure set up, and then switch to Arcadia. I hear that the Arcadia bulbs output holds up after a few feet vs 12". Is that correct as well? When he saw the vet, she said that continuing to use the calcium dust with d3 in it was safe, even with the uvb bulb. I've heard mixed reviews on using both at the same time. He's still currently getting the calcium dust with d3 on every other meal (every other day). I haven't seen ANY signs of MBD at all. No rubbery jaw or weird toes or anything. He'll probably be going back to the vet this weekend for a worming, and definitely to get a different or updated dosing for his URI which is still creeping around (breathing different when active/stressed than when resting) so I can double check about the dust with d3 if no one is really sure.
