IR thermometer misleading numbers?

Hi there, I bought an IR thermometer a few months ago and measured some emitter temps while running a flashlight. While some lights give some reasonable numbers others are just ?scary?

I measured my Moddoo Triple with a single AW 2600 cell. Current draw is at 2.6A with a fresh cell. The emitters go up to 148°C in less than a minute, which is just under the max junction temperature. My Catapult XM-L for example never goes above 125°C.

Are these numbers too high?

BTW the head temperature seems perfectly fine with 42°C after 5 minutes. I think the heat gets transfered well.
