If I take the LED light off, will the power still work?

You are confusing what can and can't kill with relative levels of risk.  An arm-to-arm or arm-to-leg shock is potentially more likely to kill you (everything else being equal), but that isn't the same as saying that contact with only one body part (and you didn't mention the thumb in your previous post) will only hurt rather than kill.

The point - simply - is that mains-voltage is always dangerous.  An isolating transformer reduces risk, it doesn't eliminate it.

On your end point - I personally wouldn't be concerned about leaving a toothbrush or rechargeable shaver plugged in unattended, as the unit will not be expected to be used for only short periods. "Warning - use this light for 5 minutes max".

How do you know what design assumptions were made by the designer?  Many items have a duty cycle without that being stated in the form "Warning - use this light for 5 minutes max" in big letters in a location visible to the user.  A shaver point may have been designed for use with shavers only, and possibly before rechargeable ones were common.  Few people have a need to shave with an electric razor for (say) 15 minutes and therefore it wouldn't have been unreasonable for the designer to work on the basis of (say) 15 minutes max use before a period of non-use to allow cooling down.  Achieving a compact design (for example in the kind of fitting the OP has) may have made such design assumptions more necessary.

Note also that there is a difference between using the light for a longer duration, and applying an (unknown) load which might exceed the design rating of the transformer for an extended period of time. Leaving the light on with nothing plugged into the shaver socket is probably Ok.

Would you believe me if I said that I suspected you'd almost certainly react when I made the flippant 'hurt' comment'? It's true.

Of course mains voltages are highly dangerous, and those well below. You won't, tho', get an 'earthed' mains shock from an isolating trannie. It will hurt if your oversized thumb happens to span both shaver pins as you insert the plug - a near impossible scenario. And it'll certainly be very dangerous if you use both hands to insert the shaver plug, one finger of each on a separate pin.

But, seriously, folk ain't going to do this. They certainly aren't going to try it for fun having read my "it'll only hurt" comment.

Anyhoo, to even assume there could be a duty cycle for a bathroom light/shaver fitting is bonkers. "How do I know?", you ask. I don't. But it would - of course - be bonkers. And a mains-powered shaver takes a far larger current than a rechargeable toothbrush.

Most shaver outlets are NOT designed to be used with a toothbrush. Some are, however, although these contain a toothbrush symbol. Other shaver sockets are not intended to be used for prolonged periods.

Yawn... "Most"?
And, ah, the cunning use of 'designed'...
You know you are being intentionally misleading. And so do we.

There is a gnat's crotchet betwixt the power consumption of an electric toothbrush and a ditto shaver, with the shaver almost certainly being the greater if any. And there is no outlawing of charging a rechargeable shaver via these sockets, as well you know.
But, yes, many were not 'designed' for use with 'brushes for the simple reason that leccy brushes did not exist at the time.
Ye cunning wee thing, you.

The duty cycle is completely different, so you are talking absolute nonsense.

Compare the two duties for us, Risteard - show us how 'completely different' they are.

Remember - both rechargeable versions.

Bear in mind they weren't designed for charging shavers either...

Of course not.

As you no doubt point out to all yer customers; "Oi! What's this! You CHARGIN' that shaver?! C'mon here, you - now, you just tell me where it says on that unit that you can plug in a REECHAARRRGIBLE shaver, eh EH EH?! It's a bludy wonder yer 'ouse is still standing..."

Now, these duty cycles. Got any figures? Or will you accept the bleedin' obvious - that plugging in a rechargeable shaver or toothbrush presents no tangible risk whatsoever?

Transformers have completely different ratings for continuous use and intermittent use. Look at any RLV site transformer if you don't believe me.

I believe you are continuing to cunningly try and side-step the actual issue here.
So, justify your claim, if you can.
