Fall in love at first light

Big, bulletproof and built for extremes, see why the J&G Coughtrie Large Oval Fluorescent Bulkhead is the strong but sensitive type.

Flexible mounting in the Extreme

Supremely versatile, the SP-10 can be wall or ceiling mounted, in both indoor, and outdoor settings. From utility rooms, and traditional kitchens, to extreme maritime locations (did we mention it’s 1000 hour salt spray tested?) the world is your lobster.

Regal and Robust

Each light has been cast using traditional methods, using premium materials, with a solid aluminium case and chunky glass diffuser. Despite its elegant style, the SP-10 remains resolutely robust under any conditions, wet or dry.

The Sensitive Type

The SP-10 casts an imposing light, thanks to its thick, hand pressed glass diffuser, providing wide, but gentle illumination. The ceramic lamp holder can be fitted with a standard E27/B22 fluorescent bulb, for ease of use, or why not don your fancy pants, and choose a smart bulb with remote control.

Finished to your fancy

The SP-10 can be finished with several different options, to suit your flights of fancy, from chip-resistant paint in a range of colours, to an industrial aluminium finish which simply has a clear, protective lacquer applied to achieve that raw, manufactured industrial look, creating an unique and distinct finish each time. With our bespoke finishing service, you’ll also be able to specify a unique RAL colour, for powder coating.


Meet The Family

Our SP collection is made up of variations of the SP light, supplied with LED or fluorescent bulbs, clear or opal glass diffusers, and adaptive lighting controls - getting super techy, with traditional design, and robust construction.

The devil is in the details

The SP-10 has been put together with the kind of attention to detail that we’re famous for at J & G Coughtrie, with a style that’s both timeless and enduring. Beauty, and substance. That’s our bag.


Hooded Power Ports

Rear, top and bottom access for power cable connection.

Winged Screw Flanges

External screw mounting points enable the SP-10 to be quickly fixed in place for your ease - no need to open up the casing.

Glass With Class, Chaps

Thick, hand pressed, and blown glass diffuser, with distinctive decorative ribs, and our iconic Coughtrie brand mark (if we do say so ourselves).

Shaped For Service

The SP-10’s imposing yet classic oval style provides beauty with a practical purpose, for long lasting style and functionality.

Built For Extremes

The hand cast aluminium casing is salt spray certified, and section 12 tunnel approved, at home and happy as Larry in even the most extreme outdoor and maritime settings.

Screw or Push Fittings

With Bayonet Cap, or Edisson Screw lamp holder fittings, the SP-10 can also be connected with a smart bulb, and integrated within your home controls. Super fancy!
