It is around 2.3ft of the puck cable.
Thank you for your recent inquiry with The Home Depot. Currently the plug for the Commercial Electric 3-Light Black LED Puck Light Kit is not sold by itself. We appreciate your business and look forward to serving you in the future.
I can't give you any specific answer except that the plug-in voltage adapter should NOT be noisy. Most likely, it is a transformer "buzzing", but it is still nor normal. I'd recommend returning the item to Home Depot.
Yes replacements are available. Please call 678-765-2995 for customer service or email email@example.com
This transformer is electrical.
This product is not dimmable, it cannot use with dimmer switch.
Yes, it is the low voltage lights. Per puck, the rating is 3.2V.
Yes. I have mine hooked up like that.
I have a set that's been on since 2014 and they're still bright. No idea on swapping out drivers though.
