Cloverleaf Replacement Smart Start 24 Bulb

With the high performance Smart start UV, Cloverleaf has advanced technology even further towards perfection. This product gives the meticulous pond keeper a number of benefits due to its superior design and construction.


The operating costs of Smart start UVs are at least 20% lower than those of Oase, TMC, Kockney Koi, and Evolution Aqua UVs.


The Smartstart lamp has a special starter ballast unit incorporated into it that, in contrast to ordinary ballasts, provides consistent light performance all year long. Replacing the Smartstart lamp is equivalent to replacing the ballast.
Additional premium features like a visually appealing design with double seal end caps and a detachable fused quartz sleeve show that only the best materials were utilised in the development of the Smart start.
