What to know before buying

The listing gives dimensions as 12.7L x 7.6W x 3.8H centimetres in one specification and 12.7 x 7.6 x 3.8 cm; 620 g elsewhere, so verify the fixture size before buying. It also calls the lights waterproof and claims IP66, but requires caulking for wet-location installation. Confirm gang-box fit and provide an AC/DC 12V power supply, which the listing says is required but does not identify as included.

The available aggregate ratings are all five-star, but the sample is small and no written feedback is supplied. That provides little detail about brightness, installation experience or outdoor performance, so buyers should base fit and wiring decisions on the listed specifications and installation cautions.

Frequently asked questions

Does this set include a 12V power supply?

Will they fit a gang box?
