Default What AC current wave is this?


"John Fields"


** Arny has supplied the correct answer.

The CFL in my test was a single Philips "Genie" rated at 11 watts.

The PROBLEM is that it APPEARS to a user to work more or less OK on a
common triac dimmer.

However, the RMS current draw when used with one is 3 to 6 times the value
normally seen - which will soon over temp an internal 10 ohm resistor in
line with the AC supply. Smoke and fire is the result.

With several CFLs on the same dimmer circuit - the combined current peaks
will likely destroy the triac in a few seconds.

Makers supply either NO warning or a completely inadequate warning of this
serious hazard to purchasers.

With the impending ban on incandescent lamps here in Australia plus Europe
and elsewhere - this is gonna cause a major safety issue.


Very nice.

Thanks. :-)




** Coming from you, John - that is a rare compliment.
