23x10mm Surface Mount LED Strip Channel For Flexible Light Strip Installations - Universal - LS2310 Series
[LS2310]

Excellent quality, and easy to install and remove lens, although a little pricey for my particular application. One point on the packaging,, one end was a little bent, as the very rugged packaging was 6ft long whereas housing was 2m, I managed to straighten and hid the bend wave.
