GEC Z5555 (Small Oxford) Lantern Installations
This page lists and covers the entire range of GEC's Small Oxford lantern, as the range is fairly extensive and telling them apart can be very difficult from the outside. This range includes the: Z5543B for 125W MBF/V, Z5545SB and Z5555SB for 60W-200W GLS (BC), Z5546SB and Z5556SB for 80W-125W MB/V, Z5547SB and Z5557SB for 60W-200W GLS (ES), Z5548B and Z5558B for 45W SO/V, and the Z5549B and Z5559B for 80W MBF/V. Thank you to Simon Cornwell's site for this information.
