Does this device consume less electricity when dimmed ? If yes, what is the curve between lumens and watts ?

Yes. I think only old rheostats consumed the same power when dimmed. I would expect the lumens per Watt to remain nearly constant with LED sources, decay somewhat (higher LPW) with fluorescent, and decay significantly with incandescent sources. This is not because of inefficiency in the device, but because incandescent bulbs are have higher LPW when at lower filament temperatures. Also, incandescent lamps will have lower color temperature (redder) when dimmed, while most LEDs do not change their color temperature much when dimmed. I have not seen an actual curve. I hope this helps.

Good question, I haven't metered it to see how much it actually consumes to illuminate and manage the timer settings and such... I did refer back to the specs in the instructions pamphlet and it did not specific that.... the maximum load the switch can handle is 1800W but I know that's not what you're asking.

I'm not sure, I stated that the brightness was with incandescent lighting,but am actually using the spiral energy saving equivalent (smaller size T2). Since three bulbs are used, with the energy saver the lamp illuminates very well. Hope this helps.

I did not change my dimmer and they dim reasonably well. Unlike incandescent lights they do not get warmer as they dim so the dimmed state is not the most attractive. Often the problem is that the current draw is too low for the dimmer to work; I have two of these lights on one circuit and have no problem. I did not try with just one.

Richard, Not really. The panel and power supply will demand a certain amount of power. Some might suggest that changing your settings from bright to dim may change the power consumption, but the difference in power usage is minimal. Thanks for your interest in Samsung products. --Mr. S

60 watts if incandescent but with energy efficient bulbs can yield more equivalent lumens with less heat

The light stays on but I believe you can dim it! It's not really that bright. It's dimmer than a 7 watt night light!

Use 15 watts or night lights. They will cut down the brightness. You can only use one bulb also to cut down on the brightness. I use 25 watts and it is good foe me. Dimmers are useless as the light does not dim. But if you like a certain bulb and its color and it is dimmable you can still use it. I hope this covers about everythinh

I've never done a calculation on it, but these lights can't use more that a few watts per hour due to being LED.If I had to venture a guess, MAYBE $1 a month to run 2 every night. That's probably overestimating.

I just tested this on a 750W bulb. The following behavior was observed: With the dimmer plugged into the wall, plugging in the lamp caused a red light on the dimmer to illuminate. No light was observed from the lamp. Upon moving the slider up a few millimeters I could hear a voltage applied to the lamp, no light though (no enough power). As I moved it up the lamp illuminated. So in short, I think in its lowest most setting you should not have any current. So no power. Update: I just tested this on a 75 W bulb, same behavior.

I would assume so; though I'm not an an expect I'm this area.dimming always lower power usage.

I actually also bought a dimming socket and use the Cree LED light 60w that dims. works great for that.

Incandecent bulbs have always incorrectly used watts to represent brightness. Lumens measure brightness. Watts measure the energy consumed. 17 watts is less than 60 watts. If your fixture is rated for 60w and you are using a 17w LED, you will be fine. I've used mine in a similar rated fixture for several months now. My house has not burned down.

No power consumption is given - it is a very bright array of LED's (28!) - almost too bright for my purpose of a key-board light - almost like a small desk lamp.So, based on brightness alone, it is not the lowest one out there for low power. Good light source however -

Yes, using the dimmer and lowering the lighting level reduces your electrical usage.

This uses 2watt and output light about 10 to 20 watt bulb equivalent. I am not too sure because I have not seen a 20 watt bulb. Definitely dimmer than a 40 watt bulb.

The device is rated at .8 of a watt. In the worst case, if it runs in a room that stays completely dark 24 hours a day (e.g., never shuts off), for 30.25 days a month it will consume about 6.3 cents of electric power per month, assuming that you pay about 11 cents per kilowatt hour including taxes (as I do). The calculation is .8 watts * 24 hours * 30.25 days / 1000 watts (kilowatt) * .11 (the cost of a kilowatt hour). Your actual cost will probably be something less, because light in the room will shut the light off for some part of the day, and some light in the room will cause the device to dim and thereby also use less power than the .8 watt that it is rated at.
