The lamp has at the top of Stan foot 10 small dimmable in three steps SMD LEDs with a total output of 5W. The "touch switch" the lamp is sensitive to touch. If you tap him when switched off, the weakest level light illuminates. Another tap, the lamp can light up on medium heat and touch again to activate the third and brightest level (400 lm).
If you want to illuminate a room properly, you can save, depending on the size of the space in two of these lamps that light up at full power, turning on an overhead light prevailed, because two times 400 lm give quite a bit of light from.
The lamp with a color temperature of 3000K (Kelvin), which corresponds to warm white and my feeling, the light of a halogen bulb comes close. Thus, this lamp is ideal for the bedroom, as it emits comforting warm-white and not a cold white light.
Since the lamp with LEDs is operated, can be expected with a very long life, so you are turning out for many years and no thoughts have to do Replace the light bulb, as this simply waived if LEDs. The average service life of LEDs this lamp is indicated on the Amazon product page with 30,000 hours, which corresponds to 1250 days or nearly 3.5 years of continuous operation. Since this lamp is to be used just when used as a bedroom lamp far less than 24 hours per day, one must adjust well to a very long life of this lamp.
The review of the attached picture shows the positioning and arrangement of the 10 LEDs.
I am with this lamp far fully satisfied. Through three brightness levels it can be adapted very well and never lights too bright or too dark. I like to give a buy recommendation.
