These architectural tubes are typically used in concealed lighting & exhibition lighting systems, for example, in high quality bathrooms, reception areas, museum cases & displays. Rear sited pegs Their pegs are at the rear, meaning they can be placed end to end to give a continuous line of light. They can provide a unique light curtain effect on any flat wall, with no visible light source. The seamless look these lamps provide are ideal for making the most of any architectural feature too. Oblong or Round Peg The oblong peg tubes are available in opal & the round peg tubes are available in pearl.
