Warranty is useless.

Bought lots of lights from them for our house and sent an outdoor led wall back to them that stopped working after 5 months. Was then told that they won’t replace it because the rubber grommet on the back is not on there. When the light was removed it fell on the grass and I did not see it come off, only a day later once it was sent to them already did I find it on the grass. They say that it has water damage but how does that happen with a grommet in. Clearly they are not wanting to honour their product.
