Ambient temp seems to depend on the equipment. I have two 22-watt heat plates and have used those in freezing or single-digit temps for years with no issues. I recently ordered and tested a 20-watt heat plate and it didn't get as warm, so I'm thinking it might require higher ambient temps or be better suited for older chicks.I don't think those chicks are cold
Heat lamps are dang near impossible to regulate the heat at 95 degrees. I just set my brooder up today with a heat lamp - my Brinsea heat plate quit working (need a new power transformer)
But I have it rigged to give them ample heat on one end and plenty of room for them to get out of the heat and self regulate. They will only be in this for a few days before I move them to the in-coop brooder. Ambient temp was 50 degrees and the temp where the thermo was under the heat lamp was 88.

Heat plates are only good to about 50 degrees ambient temp. That's what the mfg suggests anyway. I don't think there is a set temp ambient temp should be. But the colder the ambient temp the more you will want to have a suitable heat source for the chicks to stay warm. They will self regulate but a heat plate probably won't be enough if it's 20 degrees ambient.
Since @Anchors1411 mentioned that they couldn't hold their hand on the heat plate for longer than 20 seconds or so, I think it's higher wattage so it *should* be okay. Of course, I'd encourage anyone to check manuf instructions with any brooder equipment.
