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? -- Rick |

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. -- ================== Remove the "x" from my email address Jerry, AI0K ================== |
