Question: What color is led, white or warm white?Thank you.
Document: LEDs, like fluorescent lights, are typically very stark in color. Most &#34;white&#34; LED lights I've seen are too blue: not conducive to reading or any activity where warm light is best. But these lights have the warmth of a halogen or standard light bulb.Like most Ikea items, some construction is required with the desk lamps (the clamp-on variety is ready to go, BTW.) In this case, it's minimal.
I was worried that this lamp wouldn't be bright enough. I couldn't have been more wrong. If you stretch the goose neck all of the way out and point the tip down it makes about a 12" well lit circle. The description says "warm white", but it looks more like a cool color to me. Regardless, the color renders great and it is blindingly bright. It is the absolutely perfect little task light, puts plenty of light right were you need it and nowhere else.
The Small footprint takes up very little space and the goose neck allows you to put the light where needed or aim straight up for a nice area light glow off your ceiling. Being led uses very little energy. This is not one of those really harsh white lights it's a very warm yellowish tint like the old bulbs that are being phased out. Nice combination with the technology of today with the feel of the old school lights. I use them everyday and have yet to have any problem from any of the three.
Nice for small places that need excellent, directed lighting. Spotlight quality. Sleek design. Would buy again, perhaps in the white color, if available or other colors, too!
This is the best little desk lamp. I picked up a LED with a clamp on it from another store and was so impressed that I had to have more LED lamps. Since I was moving the lamp around, I thought just by extras, and a lamp with a base was next. This base is just heavy enough to hold the lamp at any position, the light output is a warm white, but very bright. Point it towards the ceiling and use it as a night light.
Recently purchased this desk lamp to help with school studies, and I'm happy with this product.Pros:- Light weight- LED (light doesn't emit heat, though light head becomes somewhat warm but not hot)- Goose neck is very stable and versatile- Focus light is perfect, provides adequate warm light- Easy set-up, took me 2 minutes.Cons- More color options should be availableOverall, I am happy with this product, worth the money certainly.
The light output from this little light is excellent. Good color balance. Very nice for reading or computer work. Highly recommended.
Five star because I know how good this product is. Sturdy and last a long time. I bought same product three years ago except different color and it is still working.
Works well in a small dorm room! And I love the orange light it feels warm. And this lamp can turn around freely l, very convenient!
the item requires assembling, glad the person i am giving it to is over 12 yrs old and can take care of it.it is a lot, lot heavier than i thought it would be.Arrived safe and sound and on time. will find out soon if it works.thank you
