Question about bulb for heat lamp

[KWALA]

So I know the temps I need for my cage in basking,day, and night but the heat bulb I bought was the only one available at the time and it is barely hitting the 85 Fahrenheit mark in the basking spot so I imagine it's not 75-84 in the rest of the cage. I was wondering if you guys could link me to a good bulb that will produce good basking heat and all around cage heat for a 24x24x48?
