PL-L UV Lamps For Aquarium and Pond Use
Osram PL-L UV lamps are 4 pin high output compact lamps that can be used in a UV Clarifier or UV Seriliser for aquariums or ponds.
They are a standard size that fit many UV units.
When should you replace UV bulbs?
UV lamps loose their efficiency after around 6 month so we recommend for ponds that you replace them every spring to combat green water (algae).
For use in a steriliser after 6 months of use a replacement should be considered for optimum performance combating pathogens.
How To Change A PL-L UV Lamp?
Changing a UV bulb can sometimes be a bit difficult depending on the unit. Each unit can be a bit different so it is best to consult the manual specific to your UV unit.
If you are struggling look out for screws that may be securing the bulk head. Take care not to damage the quartz sleeve and remember not to loose any O rings that may come loose.

These UV lamps will fit many units including, Blagdon, Hozelock, Oase, Fish Mate and more. Most lamps should have writing on them with information on what size they are. If the bulb is broken try searching the make and model of contact us for help
