The LPL-EXT integrates a telescopic feature with the exceptional performance of four differently styled top assemblies. Fully collapsed the fixture measures 18" and extends to a full 36" height. Equally at home in an alpine meadow where snow accumulates, or in a lush tropical setting where rapid plant growth necessitates a height adjustable fixture. The entire assembly is machined from solid copper and brass bar with stainless steel hardware. The "water clear" lens is fabricated from heavy wall Pyrex? glass tube that features high heat resistance and superior light transmission. The LPL-EXT is built to withstand the test of time and backed by Auroralight's no-hassle Lifetime Warranty, protecting the luminaire against even accidental damage.
