So, quick quesh...I’m new to the world of chams & just got my baby nosy Faly Panther 2 weeks ago! He’s doing great but I originally bought him an 18” Zilla Tropical Slimeline T8 light fixture but read that the T5 is better...plus my terrarium is 30” long so decided to upgrade & buy the 30” Reptisun T5 HO light fixture & bulb on amazon. However, when I opened the package, the bulb is barely longer than the one I have now!! And on the box, it displays a bulb running almost the entire length of the fixture (minus an inch or so on either side) but the one I got is over 4” short on each side! Is anyone else’s like that? Is that how they advertise their product or did I buy the wrong fixture or was the wrong fixture put inside this box?! I’m so confused! Any thoughts on this? Should I just keep using the T8 & return this one? I don’t see much of a difference it would make since it’s barely only a couple inches longer. Thanks!
