I'm looking to fit some led tape lights under my kitchen cabinets,I have a 7 ft stretch then I have my cooker and another 300 mm cabinet after the cooker.Instead of having two separate installations I have buried 20 mm oval conduit in the wall which is going to be tiled over and was thinking of running the tape through that.My questions are would the heat build up in the conduit and knacker the LEDs and if so could I terminate the first 7 ft run and run a pair of singles through the conduit and connect to the rest of LEDs for the 300 mm cabinet?
