JBL Replacement Lamp UV-C 36 W

JBL Replacement Lamp UV-C 36 W is the replacement UV-C tube for JBL's 36 watt clarifiers. The tube is the part of a UV-C unit that wears out: the housing, sleeve and fittings outlast several lamps.

Key Features

• 36 watt UV-C tube: a direct replacement for the lamp in a matching JBL UV-C clarifier.
• Clears green and white cloudiness: JBL describes the tube's job as removing the greenish and whitish cloudiness caused by free-floating algae and bacteria.
• Germicidal wavelength: JBL gives the figure as 255 nm, the range that acts on algae cells and bacteria in the water.
• No effect on water values: JBL states it changes neither the water parameters nor the bacteria in the filter.
• Do not touch the glass: JBL notes that handling the tube with bare fingers shortens its service life.
• Replace on a schedule: output falls away gradually, so a working lamp is not automatically an effective one.

Good To Know

• Never touch the glass with bare fingers. JBL is explicit about this: skin oils on the tube shorten its life.
• Never run the lamp outside its housing and never look at it lit. UV-C burns eyes and skin without feeling hot.
• Switch the unit off at the mains and let it cool before you open it to change the tube.
• Clean the quartz sleeve while the unit is open. A new lamp behind a limescaled sleeve is wasted, and tap water here scales glass quickly.
• UV-C tubes lose output long before they stop lighting. Replacing one roughly once a year of continuous running is the usual advice, and a tube that still glows is not necessarily still working.
• Dispose of the old tube properly rather than in household waste.
• Match the wattage, the socket type and the tube length to your own unit before ordering. The wattage on the box does not identify a lamp on its own, and JBL has used different sockets across the range.
