Hello Guys
It seems that there is a shortage of the NDB7875 445nm 1.6W diode among several chinese suppliers. According to techhood there is a replacement coming wich is the NDB7B77. but its not widely available yet and unstable in power.
Second the NDB7777 is also a 1.6W/445nm diode wich would be also an option for me but again not available every where. Can anyone tell me what the difference is between the NDB7777 and the NBD7875?
It seems that the usual NDB7875 is no longer available in every streetcorner and the replacement is in development.
Anyone has some info what is going on?
