Hi think in this day and age John that's a bad inference.
If it's sold here and doesn't work we take it back... Brands that get a reputation, die. In the case of the lamps, it responded to transients. -----Original Message----- From: John Woodgate <[email protected]> To: [email protected] Sent: Mon, Mar 21, 2011 11:10 am Subject: Re: [PSES] Lamp dimmer interference In message <[email protected]>, dated Mon, 21 Mar 2011, Derek Walton <[email protected]> writes: >yes, the CE mark isn't just applied to Europe you know.... even if it's >not wanted. I meant that the CE mark implies that the dimmer is designed for 230 V operation. On 120 V, the triac may not trigger properly due to insufficient gate current, in which case the dimming level may vary... In due course, the triac will fail due to hot-spot formation on the die. -- OOO - Own Opinions Only.
