Customer Reviews
Great lights easy to install,don't get insects coming down from the ceiling. They are bright lights,which lights up the rooms.
Philips Tri Colour LED Downlight 9W (120mm)
We replaced 15 year old CFL down lights a number which had been replaced with E27 LED 12 watt bulbs. What we found:
+ The lights are much more efficient. So they are brighter.
+ They are also emitting light from the same level as the ceiling as the diffuser is closer to the ceiling surface. As a result the light emitted is a much wider angle and lights up the walls much more than earlier lights.
+ As we are both over 70 years old, all the lights inside are set to daylight 6500k, with the external ( deck etc) set to neutral white 4000k. this is good for use but our son in his mid 40’s would set them down one. So they are good to suit various users, and are easily changed.
+ They changed the décor of our ceiling as the lights are not as obvious as the darker ones they replaced.
Very happy
Fantastic downlights at a great price. Fast service and delivery
I was under the pump as painters were due in 1 week and I still hadn’t updated my downlights. I did my shopping on line and found exactly what I needed at Reduction Revolution, ordered them that day (Tuesday) and wow, they arrived Friday. My electrician installed them (all 7) on the Saturday and now I am all ready for Monday. I have never had such a quick and smooth process. I can’t recommend RR enough for their range of products and their speed at delivering
