Delta UV Series 40 Lamp 70-18440-S

Genuine Delta UV replacement Lamp for E-40 Series, ES-40 Series and EP-40 Series UV Systems.

Why do you need a proper bulb for your UV system? At 254 nanometers, the optimum wavelength for destroying micro-organisms (viruses, bacteria, algae, yeast, mold, etc.), Delta UV-C rays penetrate and disrupt their DNA, permanently deactivating germ cell metabolism so they cannot reproduce. This is how your UV system is designed to work and why regularly replacing your UV lamps and using the correct bulbs is so important. Without UV lamps specifically designed to operate within the flow rates, water pressure, light wavelength and millijoules output for your UV system, you will not receive the desired benefits from you UV System.

Delta UV 40 Series Lamp Features:

  • Performance in millijoules per cm2 at actual recommended flow rates: 30mJ/cm2
  • Lamp: High Output – Low Pressure (13,000 Expected Life)


  • Do not touch the UV bulb glass with your bare hands. That can shorten its life. Grasp the bulb on the white ceramic prong end or use a soft clean cotton cloth or clean cotton gloves to handle the UV bulb. (If you have touched the bulb with your bare hands, you must wipe the bulb glass off with spirit vinegar using a clean soft cotton cloth)
