LED DD Retrofitting Instructions

Please read these instructions thoroughly before use.

All conversions should be carried out by a qualified electrician.

Fitting Conversion

The existing fitting must be switched off and isolated at the mains before commencing electrical work.

It is the responsibility of the converter to ensure the fitting continues to meet safety requirements.

For maximum energy savings, bypass all control gear and wire from the mains to the
lamp holder as for an electronic high-frequency ballast conversion.

Magnetic Ballast (Choke):

Remove the starter and any power factor capacitor. The capacitor may be left in place but the energy
savings will be less.
Plug the LED DD lamp directly into the lamp holder.

Electronic Ballast (High Frequency) Conversion:

The electronic ballast is not required so it must be removed or bypassed.
Wire the Live and Neutral directly from the supply to the lamp holder terminals as per below.
The Live and Neutral must be wired to opposite terminals on the lamp holder and not be wired to
terminals on the same side.
A 1A fuse may be added between the Live supply and the lamp holder to prevent the circuit from
cutting out in the event of a fault in a single luminaire.
