Powersun 100 watt vs t-rex mercury vapor???

Question

which would be better? obviously both would be 100w

Answer 1

t-rex is rated better at a site i was at. science proves it does more, and if you are lucky like me, i live in san diego the maker of t rex started hear at my friends pet store. he is arrogant, but he is rich knows what he doing.

Answer 2

The T-Rex is a much better UVB light, much more output.  Since they are both Mercury Vapor Bulbs, they only need to be replaced once a year.  

Answer 3

I like the T rex. Had some issues with the power sun. They sent a new one but just a hassle.

If you get your tort outside in the summer you will have natural UV  will only need the UV / heat in winter.
