My light fixture fit perfectly and I like the white matches. Would recommend to anyway way better then hardware store options. I used it on wood stud but I’m sure it’s versatile. Review: Solid build, Easy install, lots of options. - Didn't realize the flood lights I ordered weren't going to mount on a deck without a box, so I quickly settled on these. Pros: * Looks great, feels very sturdy. * No sharp edges, & White is way better looking than bare metal. * Great size, with plenty of room inside to store wires & wire-nuts. * Fit my fixture, & fits at least 2 fixture sizes, as there are 2 sets of screw sockets to choose from. * Easy to mount to outside wall, or deck. No need to cut a hole to recess it into. Yay! * Plenty of choices on how to feed the wire in, & out, if need be. 4 threaded side holes, & 1 Back hole, with 4 little screw in plugs to keep critters & the weather out, when not in use. Cons: * None for me, but if you need it to go into a recessed hole, this is probably not the one to choose. The mounting tabs will surely get in your way. You may think there's not much difference between one electrical box and another, but there really is. This one is very nice compared to all others I've used. (a Lot). That coating is way nicer to your hands, too. No sharp edges on mine.

I have a flood light installed on it. It has been there for 2 years, at least, and the light is still working like new. The light fixture fits well on the box. ## Frequently Bought Together - Sigma Engineered Solutions, White Sigma Electric 143854WH 1/2-Inch 5 Hole Round Box - Ring Floodlight Cam Wired Plus with motion-activated 1080p HD video, Black (2021 release) - LUTEC 72W 7500LM LED Security Lights Motion Sensor Light Outdoor, 5000K Daylight, IP65 Waterproof, Dusk to Dawn, 3-Head Motion Detected Flood Light for Garage, Yard, Porch(White) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pl/products/38538422-sigma-engineered-solutions-143854-round-metal-electrical-outlet-box-weatherproof](https://www.desertcart.pl/products/38538422-sigma-engineered-solutions-143854-round-metal-electrical-outlet-box-weatherproof) --- *Product available on Desertcart Poland* *Store origin: PL* *Last updated: 2026-04-24*
