After a number of years, quite a few Hue light strips were installed in the house for indirect light applications, a total of 40 meters. Always satisfied, some LED strips stripped of their silicone jacket and mounted in LED rails with diffuser. Litcessory attachments used for corners, edges and bridging (can't understand why philips doesn't put together a pack like that). Also learned to always clean surfaces with alcohol (for solid surfaces) so that the adhesive strips hold (if no rails are used). What really bothers me, however, is how philips is letting its V3 customers suffocate! Neither V3 extensions nor basic kits are (easily) available anymore. if you want to expand your V3 installation you can forget about it and have to replace everything with V4. If 1 meter is damaged during a renovation, ditto, you can remove the entire 10 meter and replace it with V4. Thought you were smart and keep a small replacement stock with V3, nice until a controller strip breaks down, then you can still throw away your stock and replace everything with V4. Thank you Philips for rewarding your loyal customers! We also use Lifx LED strips for certain lighting applications and we don't have that problem at all. If you keep these things in mind (that there will ever be a V5 version where Philips will treat its customers in the same way), then it is best to have a good LED strip with a large light output. With the V3 version it was the case that once you went over 6 meters most controllers make a high frequency irritating noise, I don't know if this is also the case with the V4 version.
