Bad reviews on Amazon. Also, pics (no labels) and description do not mention whether or not these are UL approved or equivalent. No way I would plug them in my house.
"claims to save energy ."
That's questionable, these things have a constant ghost load when they're off.
we have a 3-way touch lamp and i was curious if it had any ghost load to it. so i got out the kill-a-watt meter and tested it. there is no ghost load according to the kill-a-watt meter, but there might be very tiny ghost load that the kill-a-watt meter cant register.
Saving energy would be about running the bulb at lower power. HOWEVER, at anything other than max power the bulb is far less efficient. For example, running a 60W bulb at the amount of power it takes to produce the same light as a 40W bulb would, it'll consume more than 40W.
On the other hand, running at 40W it should also last a lot longer than the 40W bulb does which could be important once all incan bulbs are outlawed, except that if you have to cycle it down to 40W equivalent every time you turn it on, it still suffers the initial turn-on filament expansion shock so in that case it won't make much difference.
Anything that doesn't have a mechanical AC power interrupt switch has a ghost power factor, though usually quite low if the device only uses the ghost power to turn on, not power a display and perform logic functions. In winter subtract that from your heating bill, every watt lost is converted to heat. Vice-versa in summer.
A Kill-A-Watt meter can't measure accurately below about 3W, maybe even 5W depending on your degree of accuracy required.
