A light to check whether I still got the hang of soldering. It has been a while since Leds and Meds, which I worked on until around 2014. Now, is this a led with a fan or is it a fan with a led? The fan suggests that the led gets very hot. But on the contrary, this type of led hardly emits heat at all, compared to the brightness. Probably even less than the fan itself. It does send out very bright light though, even more so because of the dramatic presence of the fan, suggesting a lot of heat which makes the light even brighter.
