The new Source 4WRD LED light engine is backwards compatible with all exisiting Source Four Spot fixtures (excluding Source Four Mini) and the brand new Source 4WRD PAR and PARNel bodies; sold separately.
Source 4WRD can be retrofitted to your current Source Four Spot fixtures in as little as 14 seconds with just a screwdriver and spanner (not included), requiring minimal technical expertise. Simply remove the current discharge housing, screw in the included adapter post and install the Source 4WRD engine. See the retrofit in progress here:
