I've been using the Zoo Med Reptisun 10.0 T5 HO for a while now but recently they have been hard to find locally. Seems most carry the Zilla Desert 50 T5. Anyone use these? Are they any good? Has anyone used a solarmeter on one? I would prefer to buy locally as I don't want to run the risk of a broken bulb and the headache of shipping back etc. Thanks.
