Excellent product. Nice and bright. Fits standard 125mm holes. Do note these are the larger size holes though, not the little 70mm or 90mm your 12 volt downlights use. This is a really great light and the control with Alexa and the Hue Bridge is fantastic.
Although Philips Hue lighting can be expensive, the products are reliable and always evolving. These particular downlights are bright and responsive to the Hue app. We are now saving money to replace another 6 in our home.
I initially bought 3 of these lights for the kitchen to replace some GU 5.3's as i wasnt 100% sure if i would like them.
As soon as i installed them and turned them on, a smile lit up along with the lights. They look very clean and modern and i'm super happy with the light. The brightness is perfect, and being able to dim and set the colour temperature from warm to daylight means they can be set exactly as you like them.
Adding them to the Hue app, adding to Alexa was all very simple. I've added hue sensors so they come on when you walk in to the kitchen and go off when you walk out.
Love them so much i bought 9 more for the hallways. Super happy.
Uses less power than the 50W halogens it replaces and also fits well into the Hue ecosystem. If retrofitting existing downlights, will require cutting a bigger hole in the ceiling. Not an issue in a new build.
