    Very good heat sink for classic 12mm diameter laser diode. I'm using it on my 3D printer to engrave and cut. For 250mW laser is enough and the laser work w/o extra temperature

    these are good quality, they have a very nice black surface finish, they have a hole in the bottom that fits a 3/8 inch bolt, the same size as used for cameras, so you can bolt this on a 3/8 camera stand/mount/tripod/adapter etc to position them and adjust and fixate them easily in a position. Delivery was very fast

    I have a 250mW laser module coming from Banggood as well. When not using this heatsink, I can't use it more than 2 minutes because it become very hot. But when using this heatsink, it doesn't heats up at all ! It's super great ! I use it for my DIY laser engraver made from a scanner and a printer. It's really nice for long engraving runs. I really recommend it !

    This device helps to prevent overheated laserdiodes in the common used housing. For about 50mW LD the small tubehouse will do , but for a 2 Watt???!! Then these laser host base heat sink really will be needed so a fan can lead the heat away from the LD and prevent overheating from the LD. With a bare LD you have NO guaranty but when you buy it in a housing the LD always works THAT is my experience. The next trouble is that the housing however does not support cooling and to get the LD out of the housing is not a succes. So this heatsink is a good solution
