How do you explain the manufacturer of dimmers says standard dimmers
cannot be used reliably?

Because the manufacturer wants to sell their dimmers and their bulbs.

Use Phillips bulbs and there is no problem

Then why do all manufacturers say the same thing?

And exactly what are the qualifications of the author? A "text-based
adventure connoisseur"?

I'll believe the engineers who design dimmers, not the funny pages.


You are being a bit silly about this. The guy did a *test* which was
clearly pretty thorough, thorough enough that he could detect *and*
record the flickering of the bulbs when dimmed. He pretty clearly
doesn't have a manufacturer bias since the same company had the bulb
that tested as the best and another which tested as the worst in the group.

Unless the guy has a reputation for faking such tests, why would you
doubt his work? Ignoring valid test data and preferring the opinion of
manufacturers who have a clear stake in the game just seems odd.

Do you deny that the tests show at least one brand and model LED bulb
works perfectly well with a legacy dimmer?


The guy is not an engineer - and AFAICT, has no engineering experience
at all. And I don't trust ANY tests performed by untrained personnel.

And all it shows is that ONE bulb worked properly with ONE dimmer. It
doesn't say how LONG it worked, for instance.


Did you actually *look* at the info?
