Worked just fine out of the box. They are extremely bright. Almost too bright for my eyes if that's even a thing. The lights add plenty of illumination for my wife to work on her pottery.best best best 10 startSeriously the best garage light I've ever seenWe installed it in our barn and it far better the a 200 watt light bulbI would recommend it to anyone who had a space needing lightThis light fixture looks beautiful in my bathroom. It was easy to install. My only complaint is that it isn't super bright, it's just enough light. I like my bathroom to be bright, especially when doing my hair and makeup. I am going to have to put an additional light in or put a brighter one in the ventilation fan.This sleek lighting fixture has an appealing contemporary design and is easy to install. Although there are no written instructions, it comes with pictograms that are fairly straightforward and simple to follow. One of its most appealing features is that it uses LED clusters to provide the illumination, rather than replaceable light bulbs. The good news is that you'll never have to replace a bulb; the bad news, I suppose, is that if an LED ever fails, you'll have to replace the entire fixture. But given the nearly indefinite lifespan of the LEDs, the great probability is that for most users, the fixture will outlast the user. (Is that really good news? I guess it depends how you look at it.)One nice feature of the LED lamps, as opposed to halogen or other incandescent ones, is that there is no need for the heat-absorbing insulation that's packed in behind those old-fashioned, heat-producing,, bulbs. This makes for a much cleaner installation. Not to mention all the electricity you'll save by using LED lamps.Before you buy, please be aware that at 6000K, this is in the the cool range of colors. (Most incandescent and halogen bulbs are in the 2700-3000K range, where the light is warm and yellowish; 5500 counts as "pure white"; 4000-5000K as "natural white.") The color is not adjustable. (Some fixtures do feature an adjustable color temperature, but not this one.)The fixture is advertised as being dimmable, and it is. But I noticed that the range of adjustability (at least with a standard dimmer, like the one I'm using) is not as great is it was with the halogen fixture I'm replacing.So with these caveats in mind, I'd say go ahead and get this fixture if the style appeals to you. It appears to be very well made and looks quite durable.This light is sleek and modern and provides a good amount of light. Installation is straight forward. This is the perfect size for my 30 inch vanity. ExcellentReplaced my 15 yr old fixture with this beauty. It matches our black/white bathroom theme.The light output is very generous an a cool white, which I like. The installation was straight forward, my electrician said it was standard. The light diffuses the light evenly, it does not show any hot spots on the lamps.Very nice product.Hope this helps!I was hoping for a better quality light. It worked fine, just cheaper build quality. Also wasn’t as bright as our current light fixture. We ended up returning it unfortunately.
