Crompton Robust (Transparent cover)

Another popular SOX bulkhead; the Robust was one of Crompton's 'famous' designs. It could either be used with SOX or fluorescent lamps and had the option of having a clear or opal bowl. This example features the former type, however I also have an opal-bowled example in the Collection; click here for details.

The Robust certainly looks like it lives up to its name - notice the two anti-vandal bolts which hold the cover in place.

With the cover and reflector removed, the fitting's gear can be seen - this simply comprises a ballast and a capacitor.

 
 

I powered the Robust up on Saturday, 21st July 2007 - the clear cover meant that the operation of the lamp could be seen perfectly.
