No, you'd have to send the light back in to get the beam angle strip replaced. We seal these into the fixture to meet our standards for IP66 Waterproof Rating (water-splash safe), so if you open it up the warranty is voided. Feel free to ask questions here or give us a call at 512-382-5881 if you have questions about which beam angle best suits your tank needs.
