This product is a little light at first. It does not seem very strong and yet I fully open I removed the LED protection and despite the appearance it has good strength. LEDs provide sufficient lighting and cozy because it's not too hard to play. The lamp is designed to be connected to a computer but as it consumes only a mAh I plugged directly to a backup battery as shown in the photo. This allows me to make a lamp with switch that I can use in my bed for reading. On a battery of about 10 000 milliamps as the one I technically can fit 10 000 hours it consumes very little. It is also very light as weighing less than 50 g. This is a very practical product, the finish is not great but far from it does the trick. I add that I have tested this product at the request of the seller but my test remains independent.
