Fellow Growers, I need some advice on where to buy some quality 100k pots for dimming my HLG drivers.

I have been using these https://www.amazon.com/gp/product/B00YX8TJAW/ref=oh_aui_detailpage_o03_s00?ie=UTF8&psc=1
and they are crap. I have replaced them twice and already need to replace again.

Any suggestions?? Thanks and Gl OG

You can get these precision 10 turn pots from China for cheap but buy them here in the states they will cost you close to 20 dollars. https://www.ebay.com/itm/3590S-Prec...hash=item1a1ff5da5c:m:m2AujGozPU0jiR_sP_lTVsQ The fucked up thing is they are made in Mexico but it is cheaper to send them to china and have them sell you one and ship it here. lol

Look up linear VS logarithmic potentiometers... I suspect you picked the wrong one.

best ones I found work great and are 100K or 50Kas advertised

Buy sealed. They usually have 1/8 shafts. I purchased mine from fleabay.

Dust can be a problem.

This is what I use. Although one of the pots failed on installation-I ended up using the second to control both drivers-it's been in use for about 3 months now.
