biOrb transformers are very reliable and rarely need replacing, if yours has stopped working and you have a standard light unit check that the last bulb you fitted was the right size. If you have fitted a larger bulb it will 'blow' the transformer and stop it working. If this is the case replace the bulb before plugging into your new transformer.

Suitable for Baby biOrb; Classic 30, 60, 105; Tube 15, 30 and 35; Life 30, 45, 60; Flow 15, 30.
