?

Hey guys, anyone know how\where I should measure the current operating temperature of a Clu048? I want to make sure that the heatsink I have is doing its job and that I haven't screwed something up. I have a laser thermometer.

I have the same question for my CXM-22 COBs. According to the spec sheet, operating case temp is 105C, junction temp is 140C . I don't know what either of those means, but my heatsinks are steady at 50C.

I think that those are the max temps that the chip will survive. Seems that you have plenty of wiggle room @50degC. Most manufacturers will give you specs on how they collect measurements so try a little surfing.

would suggest such a cheap ir temp gun too, ebay amazon or this harbor freight ( which idk).
I have f.e. ca. 50 on my cob direct and 35 celcius on the heatsink, if i remember right, was all healty, i use the ir temp gum more to check the temp of the plants, hint ;-)
Well spend 20 bucks i would say.
