Gruenlich LED Flush Mount Ceiling Lighting Fixture, 9 Inch Dimmable 15.5W 1050 Lumen, Aluminum Housing Plus PC Cover, ETL and Damp Location Rated, 2-Pack (White Finish-3000K)

Like most product sold on this website, you have to modify or repair it on delivery. This one is no exception. I got into the habit of opening up everything I receive nowadays. Out of the two lights, one had a short between the live and neutral. A small strand of wire was soldered across on the PCB. This was easy to snip out. My guess is on the first power up, the strand would have melted away, and probably become harmless. But it could as well have been a fire hazard.The product is sold as 24W, 1550 Lumen, >=80 CRI. The reality is 26W, 1400 Lumen, 80 CRI. In fact it is nicely spelled out on the PCB. Which also informs us that there is 30 LEDs, split into two strings of 15.This gives us about 0.86W per 9V LED chip. Which is close to their maximum rating of 1W.There is a slight 120hz flicker (visible on slow motion camera).On the PCB, the current to the LED chips is controlled by the three groups of resistors conveniently labelled RS* (Resistor Sense). The board is basically three copies of the now relatively common circuitry you find in LED light bulbs. This makes modification trivial.On this board, every group has about 8.9 Ohm of resistance. Split between one 3.9 Ohm resistor and two 10 Ohm in series (making it 5 Ohm).Snipping one of the two smaller 10 Ohm RS resistor in the three groups (example, RS2, RS6, RS8) will reduce the power consumption to 12W. It is almost as if the PCB was designed so you could do that in seconds when you know the trick. This brings the power consumption to 0.4W per LED chip. The light fixture will run cooler, be cheaper to run, the LEDs will last 10 time longer, and all of that for only 30% less light output. In my case, 1400 Lumen was too bright. It would hurt just looking at the light fixture. Lowering to around 900 lumen is just perfect.The aluminum PCB appears well built and thick. At 12W this light fixture should last pretty much forever.

Nice looking lights. And the light is very clear. Love these.

This was easy to install and looks really good.

Bright and lite. Great replacement and energy efficient

It is too small for our hallway

Very bight, I liked the options of choosing the brightness by using the daylight, bright, or warm switch. All have worked well right out of the box. My only problem is the tolerance for installation. They have a mounting bracket that includes a screw for fastening the ground wire. The screw head plus ground wire may be enough to keep the unit from fitting tight to the ceiling.

Would order again.

I installed these a few weeks ago and one of the lights has stopped working. I threw the box away and cannot return them. I also already threw the old lights away and would have no lights in my closet until I can get new ones. I contacted the seller and they responded right away and took care of the issue. The problem was with the light, but this seller was responsive and quick to resolve the problem.

Tienen un tamaño pequeño, por ello decidí ponerlo en un pasillo, me sorprendí que iluminan muchísimo.

Son muy chicas para que luzcan bien en lugares amplios.

EStan muy padres, me agrada que cambia la luz según el lugar donde las coloques, precio de acuerdo a la calidad

La luz es normal pero lo tan potente

Muy bonitas lamparas iluminan super bien y se ven muy bonitas.
