Recently, one of my basking bulbs in my tank stopped working (I have 2). Originally, I've been using the Exo Terra Sun Glo Basking Bulb which is pretty good.
I have recently switched into a larger aquarium for my turtles (approx. 70 gallons) I have the water level filled about halfway which also means that the distance from the basking area to the bulb is greater.
What is a basking bulb that emits more heat?
Thanks!

I use a Mercury Vapor bulb - Zoo Med PowerSun UV Mercury Vapor Lamp 100 Watts. You would not need two bulbs just this one.

Just use a Powersun it's an MVB then you won't need two bulbs. They are very good and last a year. I have the 100 watt I found it online for $40. You can also get 160 watt if that's what's needed for your setup.
