Just installed these and thought I would give a few pointers that aren’t mentioned. ***This is generaladvice only and install at your own risk***. If you aren’t comfortable doing electrical work please hire a professional electrician.1. These sconces do not come with a mounting plate so you will need to purchase one (I purchase the round 5pk off Amazon https://www.amazon.com/gp/aw/d/B087QB45PQ?psc=1&ref=ppx_pop_mob_b_asin_image ). More than likely the screws in your electrician box aren’t lined up correctly so mounting plate is a must to align the lights straight vertical and also to put them at the correct height you would like.2. You will also need to purchase drywall anchors https://www.amazon.com/Drilling-Drywall-Plastic-Anchors-Screws/dp/B0845YKDHV/ref=mp_s_a_1_15_sspa?crid=KVQBKAWV2GVJ&keywords=drywall+anchors&qid=1680566717&sprefix=drywall%2Caps%2C172&sr=8-15-spons&psc=1&spLa=ZW5jcnlwdGVkUXVhbGlmaWVyPUExV09aMUlaSEo5RFZCJmVuY3J5cHRlZElkPUEwOTQ0NjM1M0U2U0IySDhBV0FEQiZlbmNyeXB0ZWRBZElkPUEwOTExNTU0MVcwQ1FaNlNEV0dMRiZ3aWRnZXROYW1lPXNwX3Bob25lX3NlYXJjaF9hdGZfbmV4dCZhY3Rpb249Y2xpY2tSZWRpcmVjdCZkb05vdExvZ0NsaWNrPXRydWU= These lights are heavy and without the anchors will sag at the top and bottom. Figure out exactly where you want your lights lined up and put holes for the drywall anchors. These are heavy so anchors are needed.3. Hang crystals last and use gloves (don’t ask how I know lol). Will make your install much easier :)4. Check your crystals. I did not receive extras of the larger crystals so I emailed the seller and they sent them out.5. Sconces don’t come with lights so you will need to purchase them as well https://www.amazon.com/gp/aw/d/B08CZGJKJQ?psc=1&ref=ppx_pop_mob_b_asin_title .Crystals are a little time consuming to out on but these are a great value, look awesome & are worth the extra time to install.
