The UTH should be enough as a source for heating..as for viewing..You can always get a viewing light if you want..(Petsmart sells this clip on red viewing light for 24.99, I bought it and use it to view Maize at night since that is when she loves to come out..It works great and doesn't give off that much heat at all (after 2 hours of having it on I felt the screen lid and it was still cool, the light wasn't even warming it that much), the down part about this light is it's kind of small and doesn't give off a lot of light..so you have to position it to where it will light up the tank just right..When I bought Striker home, he was in this tiny plastic container for over 2 hours already..I immediately set up the tank, stuck the UTH into the thermostat, filled his water dish (I fill mine with cold water because the house will bring it to room temperature anyway..) and I just put him into the tank so he could have a place to hide and not be so stressed..I kept my eye on the UTH for about 2 hours..until I knew it wasn't going to go soaring up or down and then I just let him be..I hope this helps..
