This 2 metre surface profile by Tech Light is a fantastic solution if you want to create lighting lines as it houses up to 5 standard (8mm) LED strip lights. It has an internal width of 40.8mm and a depth of 25mm. This P23-3 profile acts effectively as a heat sink meaning heat is dispersed away from the profile which improves overall longevity.
