I take a different view of Luminara candles. I think they are way overpriced for the most part.
First, full disclosure, I have tons of Luminara. But I have many Candle Impressions with the 'realistic flame look' and some from Bethlehem Lights that QVC carried a couple of years ago, with the flame look. Honeslty, the CI and BL ones are way better than my Luminara, but the selections/offerings of those other brands are much more limited, thus my having a lot of Luminara (along with the fact they were the first to come out with the technology).
The CI and BL ones don't actually have the wick move, it's the lighting that moves to make it look like a flicker. It's much more subdued and there isn't that annoying clicking sound that many Luminars have. There is less to malfunction, because when a Luminara 'wick' stops moving, it is definitely broken looking.
The CI and BL candles came in so many nicer colors and finishes than Luminara as well. Nice rustic finishes, and nice tones of tans/taupes that are great for my decor.
The BL candles actually have a touch function right on the top of the candle, to turn off, on, or set the timer so changing it doesn't require turning the candle over and removing it from the display. They even will blow out like a real candle, which is just fun. Many of my CI candles have a programmable timer, and they can be set for anywhere from one hour to 23 hours. I've found this great for using all night during storms/power outages, then easily changing when you don't need them on so long. No preset number of hours, you choose and change as needed.
And I've had a few Luminara die over the years. None of my BL and CI candles have died. Luminara seem to eat batteries faster than the other brands too.
So I like Luminara, have many, but if I could get the CI and BL brands (they just don't offer that many of them any more in CI and none in BL) I'd pick them over the Luminara every time.
