These bulbs have a 4 pin fitting at one end and are a perfect replacement for your Laguna Pressure Flo pond filter. Please ensure the correct wattage bulb is selected for your filter model. The Pressure flo 2500 and 5000 filters have an 10w/11w bulb. The 8000 model takes a 20w bulb, and the 12000 model takes a 25w bulb. It is recommended to change the UV bulb every 6-12 months, as the efficiency of the bulb diminishes over time. Regular replacement of the UV bulb and filter media will help keep your pond water clear and free from algae. Safety Note: These Replacement UV bulbs are NOT for aquarium use or aquarium lighting. For use within fully enclosed external canister filters or pond clarifiers only. Under no circumstances should you look at any illuminated UV bulb with the naked eye. Please Note: The wattage varies on these bulbs between 10w and 11w, but both will work the same. Review: A good replacement bulb for a part no longer made - This is a replacement UVC lamp for a Laguna Pressure Flo 2500 filter. My local aquatics supplier doesn’t stock the original lamps and believes they are no longer made, so a compatible part was the way forward. This lamp appears to be well made and fits neatly into the silica glass tube. Once installed and switched on, I could clearly see the UV light working the inspection window. Time will tell how effective this lamp is but so far I’m very pleased with it. Review: Worked well. - Worked on my Laguna filter and cheaper than a genuine part. Will buy again for next year. ## Features - Finest Filters quality replacement UV bulbs compatible with Laguna Pressure Flo pond filters.
