Dimmer switch no longer dims

Yes, I agree, but with 97% 5 and 4 stars and only 4% unhappy, I'll take my chances. I only need 4 for now anyway so if and when they blow I have a reserve!
I don't think so.
I have decided to replace the dimmer switch with an ordinary on/off switch.
Incidentally, I am now convinced that LEDs are the future for a number of reasons.

As I said, I've had perfectly happy experiences with decidedly 'cheap and cheerful' LED lamps/bulbs, so hopefully you will be just as lucky.
One of the problems with things like 'Amazon stars' for products like this is that, in addition to all the obvious uncertainties about such things, they can only really relate to early experiences/issues/failures. One of the main things of interest to a buy is whether it is likely to last 5,000 or 20,000 hours - and the answer to that can obviously not be obtained from any review/testimonial information.
Good luck!
Kind Regards, John
Yes, you're right of course.
There is also the opportunity to add to your comments later if and when things prove not to be as good as you first stated. I'm happy to do that, if necessary.
The lamp failure caused a surge of current through the dimmer, which caused the TRIAC to go short circuit. The TRIAC is the larger flat component with three legs or pins. If your soldering skills are up to it, you can source a matching replacement, but it might prove more expensive than simply replacing the switch.
Yes, "the opportunity exists" (or may exist) - but how many people do you think would go back after 5 years to add a comment that their LED lamp had not lasted for the expected 10 years?!
In practice, of course, the exact same product would almost certainly not still be being offered for sale 5 years down the road, so that "opportunity" might well not exist in practice!
Kind Regards, John
The dimmer switch cost only a few pounds (I can't remember the exact price) and I'm sure a replacement triac would cost not a great deal less than a replacement dimmer switch, and would entail unnecessary work on my part.
There is also the consideration that if the triac is replaced (or even the entire switch) there remains the possibility of the same problem of self-destruction through a surge of current.
In any event, the damaged switch is now in the bin, and a simple on/off switch in its place.
If anyone would like the old dimmer switch, please let me know as soon as possible before the waste bin and its contents (some of which are somewhat smelly and dirty) is disposed of. No charge, but I'd appreciate it if the buyer contributes to postage costs!
Joking apart, I'm grateful for all interest and advice received here. Thank you.
Oh, I'm afraid that's completely full, what with all the electrical work I do!
Seriously, though, you'd be surprised what goes in our bin.
