Wow 150 watt at 99 degrees for basking. I have a 50 gallon fish tank with a dimmer switch that am using a 150 watt also. Keeping a eye on the temps is a daily task because just like outside temps change. Summer is 70's in home and winter is usually high 60's or it is in my home. That will affect the lamps temp the air temp in your home. Your using a 150 watt try to adjust your basking area logs and what not to a higher point. The lamp is warmer the closer you are to it.
