What are you doing differently than allows for only a 100w bulb? Are you brooding in a heated space?
I brood outdoors in a secure coop with the pop door closed until they are feathered (for draft protection) in spring and didn't need more than 100W unless it was going to be below freezing. At those times, I swapped for a 175 and was good into the upper teens (it didn't get any colder here).
How are you measuring temperature? A thermometer measures air temp, an infrared lamp heats objects. So, the effect on a chick is not the same as the effect on the air around the chick. The thermometer is measuring the heat radiating off of surfaces and I didn't find it to be all that helpful so I just go by chick behavior. They are obvious about being too cool or too warm. I put the lamp in a corner to give them a snug and secure feeling sleeping place.
