Fluidart stainless steel ultra violet lights including replacement lamps and quartz

Fluidart Technologies Ultraviolet Sterilizer ..... Fluidart Technologies designed these lights with lasting quality and peak efficiency as top priorities. The housing of our lights are made of timeless heavy 3/16 stainless steel. They are electro polished both inside and out for beauty and function. The highly polished inside surface allows the reflectance of UV-light, increasing the intensity and killing power of the unit. Other Stainless Steel UV's on the market are only polished on the outside, but claim reflectance benefits from a dull unpolished inner surface. Our vertical design also allows for extremely easy rebulbing and the side mounted ballasts prevent the frequent over heating problems of the top mounted ballasts. We have single and double bulb units with super high intensity bulbs available in both styles. Units available for ponds from 2,500 gallons to 20,000 gallons.
