150 Watt Blacklight Night Heat Bulb.

150 watts is the highest wattage these come in.

Use in ceramic socket. 

Can be used for daytime heat too without adding extra light!

Create a great "moon light" effect while heating at night with these bulbs.

That is about 3 - 4 months under normal use on for  8 - 12 hours a day.
