which light for nano dx12

[SALTWATERSIG]

my son's 12gal dx seems to get real warm with cover closed (even with cover open) and we are thinking of upgrading to mh but i see viper 70 and there is a fixture that sits on tank with 70 watts , can anyone offer any guidance as to which one is better.
we plan to also have fan blow across top for better temp control.

I think you'll like the Current USA Sunpod 70W MH

do you still have the stock pump? if so, swap in a mj900. less watts, less heat.
