Heads Up! Tayda LDRs ----- Waitrony KE-10720

[danfrank]

Not a question but just to let everyone know...
I just bought a bunch of LDRs from Tayda Electronics, the Waitrony KE-10720, the only one that Tayda sells. When I received them they looked off. They have more squiggly lines on their face than the Waitronys Tayda sold around a year ago. I took some measurements and they are different. The old LDRs measure around 10k ohms with LEDs like the Glass Hole uses. These new LDRs measure 45-50k ohms with the same amount of yellow LED light, so they are different.
Will this make a difference in LDR projects? Who knows, but in my experience LDRs that get down to 7-10k ohms with LED light seem to work really well in these LDR projects, especially the phasers.
Has anyone else noticed the difference in LDRs that Tayda sells?

I will make a difference. I've started getting min from Small Bear because projects seem to have a more extreme requirement here lately.

Now Tayda sells two (2), count them, two types of LDRs:

All because of lil' ole' me! Lol!
It's funny, the ones they were calling KE-10720, they are now calling 5528, I guess as in GL-5528. The new LDR they are carrying is the Waitrony KE-10715. I just received some that they sent me and even though I haven't tested them yet, they do look like Waitrony LDRs. These should do nicely in optical phasers. I will report back.
Now let me say something about Tayda and their customer service... I let them know about the LDRs with the off specs and Tayda went above and beyond to make it right. They sent me the new type at their expense. They are a top notch company, I really appreciate what they did to make this right, so thanks Tayda!

Followup Question on this old thread:

To make sure I order the correct LDRs falling into the 'original Waitrony KE-10720 Specs of 10k range', which item do I order with the spec changes:

— Waitrony KE-10715

I was just about to gather the components to make some and just ran into this thread.
Just want to be sure to get the correct ones and not sure if the Data sheets are accurate..

Thanks for the help
