The Hermosa Bollard blends understated elegance with engineering features only available from Auroralight. The ALP feature adjusts lamp position relative to the cap assembly and exposes varying lens surface area, thereby controlling the amount and radial spread of light. Specify optional Directional Reflector(TM) (BDR) for horizontal beam control. Built-in vertical spread adjustment can be locked in place once set. Recommended spacing ranges from 10' on center for smaller models with low wattage lamps to 25' on center for the tallest bollards with 35 watt lamps. Select one of five mounting options, and four lamps. Optional Internal Diffuser(TM) (BID) softens light pattern around bollard, while the standard clear lens projects a defined circle of light. Manufactured exclusively in the USA by Auroralight and backed by our Lifetime Warranty.
