Day lamp is really hot! Plz help!

[GrifTheGreat]

What's the wattage on your new lamp? For a 10 gallon enclosure I would go with a very low wattage...also a dimmer is a very good idea. My white's don't like hot and bright lamps at all; I had one and I knew after one day they were not happy, as all they did was hide in a corner.
And I wouldn't sit the dome directly on the screen top of a 10 gallon (don't know if you are, but thought I'd mention it), this could possibly burn your frog; there are stands you can buy to elevate the lamp above the tank or a clamp would work too.
However, 80 degrees isn't too hot for a day time temp. I would observe his behaviour and you'll be able to tell pretty quickly if he's unhappy.

It is ok to set the lamp on the top of the screen lid if the bulbs wattage isn't too high. Most heat bulbs are only effective up to 12 inches. This will also depend on if its a 10 gallon long or 10 gallon tall though. Wattage is the main cause of issues with heat bulbs day and night types.
