[SML] "Dimmer" Is this too good to be true?

[Duncan Mahoney]

Yes, kinda snake oil.  In the text for the specs it says "This product uses the new two-way High Power SCR, Because the design of the current max up to 20 A".  I only see 1 SCR in the pictures, so my guess is it's really 2000 watts at 110 volts.   Also no UL/CSA rating, if your AHJ is going to care about such things.  I would just go with 2,000 watt "wall" dimmers, but of course those cost more than $15
