I was going to pick one up for the 65" LG C1 bedroom TV I have on order from Amazon, but I really don't like a nightlight in the bedroom. Will probably get an Anker or one of the better looking 4000J Chinese ones with lots of MOVs instead.

So too bad for that poster above. Hope he/she didn't waste too much effort making the switcheroos.
Nevermind, I see the advertisement. It's in one of the pictures in the description. So now we got conflicting reports. Guess I'll go ahead and get 1. If it's false advertising, then I'll just return.
The reviews stating a 500V clamping voltage are ALL people buying the 10 port one. The reviews for both products are commingled.
If you filter reviews for just the 12 port one, ALL of the reviews that mention clamping voltage indicate that model P12U2 is rated at 4320 Joules and has a clamping voltage of L-N 330V, L=G 400V, N=G 400V.
One of those reviews is titled 'WARNING: Inaccurate Item Description. But, a very good unit made by Dongguan Quan Sheng Electric', but the title is referring to something else being misrepresented since even that review also says the clamping voltage is 330V/400V.
https://www.power-tech.com.tw ... also reviews states that clamping voltage on new unit is 400 / 500+ and not 330V.
I bought a Belkin surge protector 15 years ago (also a SD or FW deal) from them and the Clamping Voltage is 330V. Model # F9S820-06.
However I bought 5 of the new Belkin surge protectors - model BE112230-08 - on Amazon the past year (6 actually, but 1 is still within the return period) and found out the clamping voltage is 500V (bought them before I knew more about clamping voltage; I was always focused on getting one with the highest # of joules till now, like many of us).
So I am basically out ~$100 since I am no longer confident the ones I bought the past year will protect my equipment adequately against actual surges given their 500V clamping voltage.
Ordered 6 or 7 of these 330V clamping voltage APC surge protectors today to hopefully better protect my equipment.
I did notice one poster on reddit who REPEATEDLY responds to surge protector threads about clamping voltage and has lengthy replies and seems to indicate that lots of other factors are at play, so that makes me wonder if am again wasting money on a consumer surge protector that may not do much to protect equipment in the event of real world surges - read the post(s) by westom in the following thread as one example:

EDIT - What a headache. Just saw the following article and now I am potentially reconsidering, again, whether a 330V surge protector makes sense or not:
https://www.nist.gov/document/lowernotbetterp
Quote from the article:
"Unfortunately it was not recognized that the 330 V level selected as the lowest row of that IEC table was intended for circuits up to only 50 V, not the 120 V of the consumer electronics equipment. Marketing pressure driven by the "Lower is Better" syndrome prevented a belated recognition of the disadvantages of such low clamping voltage. From the commercial-free platform of NIST, this paper, with some hindsight (work performed in the late eighties) was an attempt to call attention to the problem. In spite of this tutorial effort, the situation was not corrected and to this day, some commercial offerings still rate their clamping voltage as 330 V"

"Lower is NOT always better. Below 300V, the MOVs start tripping unnecessarily and shortening the lifespan of the protector and your equipment. Back then, when they were setting clamp voltages below 200, they just straight up caught on fire. A good rule of thumb is the best clamping voltage is around 6x whatever voltage your outlet is, so for a 110V outlet, 600V clamp is more than enough."
Hmm, first time I heard that 600V clamp is more than enough, so I am taking the LAST post above with a grain of salt.
But I did read elsewhere that 330V surge protectors have a lower life expectancy, so that part of his post has credibility. Luckily he says below 300V, whereas, luckily the APC - at 330V - is just above that...
Too bad selecting a surge protector can be so complicated (the more I research, the more I find mixed messages)...
Limited-time deal: Amazon Basics 8-Outlet Power Strip Surge Protector, 4,500 Joule - 6-Foot Cord, Black/Green https://a.co/d/528M5ZJ
However, while the Amazon Basics one has a great 4.8 rating overall, I checked a number of the negative reviews and seems this model may fail more than I would like.
Otherwise it would be a great deal given the lower price point and claimed 330V clamping voltage.
Will double check that the APC model P12U2 surge protector reviews do not mention failures as frequently as the Amazon Basics one. Otherwise I will cancel my APC order.
But appreciate the suggestion!
Does anyone have a decent alternative for one with not a bright light?
Has anyone had good success blocking out the light?

Out for a bit, but will check more when I get back.
