Each lamp is capped with a sapphire jewel to help evenly distribute the light while protecting the lamp from solvents and puncture. Contained within aluminum cylinders for additional protection" the lamps are mounted on silicone rubber cushions to withstand shock and heavy recoil. Green lamps are warranted for 12 years from the date of manufacture.
