These 2 large 180-watt units should keep my 100 cubic metre pond clear. Too early to tell effectieness as just installed and it is winter. Very easy to install onto Proficlear Premium XL drum filter with the supplied 110 to 110 mm rubber connections and the 2" to 110 mm connections for the pump hoses. The bulbs come already installed. Bulb changing looks to be very easy as the ballasts at the top of the units swivel by pressing the locking button and lift off.
