E27 LED bulbs also known as Edison Screw or ES to replace bulkhead bulbs.

Many wall lights and bulkhead lights on low voltage battery systems use these domestic size 27mm diameter Edison Screw bulb – often called ‘Bus Bulbs’ from their origins in the public transportation services. These E27 bulbs are ideal if you want to use any light fitting from the domestic market on your boat, caravan or off-grid cabin but connected to your leisure battery supply!

The E27 LED range can be used on any 12 volt and 24 volt DC lighting circuit and will withstand charging voltages, voltage spikes and fluctuations, there are no polarity considerations and they use just a fraction of the power of the incandescent original (around 1/10th). The range is available in Warm or Cool White and to make them more aesthetically pleasing if the bulb is directly visible they are also available with a smokey ‘Golfball’ style cover.
