Yes.

Large numbers of dimmable LED bulbs do an excellent campfire simulation by flickering in a very unstable way as you turn the brightness down.

Flickering is not necessarily what we're after in the living room application, though.  We are after the "red shift" as the filament runs cooler...

Not to mention the long bulb life...   probably rivaling LEDs?

I'm pretty sure that was a joke, flicker is obviously not desirable. I've found that trailing-edge dimmers work well to dim a lot of otherwise finicky LED bulbs.

Yes if you dim an incandescent lamp it can last many, many thousands of hours. As has been discussed before though, you pay for that extended life in energy costs. When an incandescent lamp is dimmed down to maybe 5% of full lumens it will still consume something like 50% of rated power. With LED the opposite is true, dim it down and it produces more lumens per watt.

suprise suprise the  government managed to get things slightly wrong with there press release.More sensible information https://www.thelia.org.uk/news/569044/LIAs-response-to-the-Government-Press-release-on-new-lighting-regulations.htm
