Local Holophane V-Maxs
Although not used in great numbers on Derbyshire's roads (unlike on Nottinghamshire's, where it is very common), the greatest quantities of the V-Max lantern can be seen in public car parks that are owned by Erewash Borough Council; these replaced floodlights running SON lamps in mid-2016.
This example is located at the end of Hastings Lane in Etwall; unusually, the V-Max is the lantern of choice for all of the roads on this housing development.
A Zodion ZCELLLED 20 Lux photocell is employed here.
A single chevron section, with its two outer LED spaces populated only, provides sufficient light coverage for these residential roads.
These V-Max lanterns can be seen in a car park just behind Tamworth Road in Long Eaton.
The twin-arm brackets were fitted along with the new lanterns; the slight difference in their paint colour (in comparison to that of the column itself) is evidence of this.
The lanterns are fitted with new-style Royce Thompson Oasis 1000 photocells. The NEMA sockets for these photocells are situated in a most curious position on the lanterns.
A characteristic of the V-Max lantern is the chevron-shaped area that houses the LEDs. The lantern is modular, and up to eight separate chevrons can be fitted.
As these lanterns are installed at higher mounting heights than the Etwall example is, here, the single chevron houses four separate clusters, with each cluster comprising four LEDs.
A large Thorn 'SONPak' floodlight existed here previously.
Single lanterns are mounted post-top to their columns.
One of the two replacements was the southbound lantern of this double-armed installation, providing a comparison between old and new.
As this section of lights is group-controlled, Royce Thompson B16 blanking cells are fitted in the V-Max NEMA sockets. Notice the retention chain that is clamped around the bracket - this is designed to prevent the lantern from falling to the ground in the event of the column being stuck.
Meanwhile, the remaining Trafficvision looks rather weather-beaten. These were installed in around late 1994, on new columns, and replaced Philips MA 60 180 Watt SOX lanterns on sheet steel Stainton columns. As the Trafficvisions were ordered with the group-switching in mind, they are not fitted with NEMA sockets at all.
These V-Max lanterns feature four separate chevrons.
Again, only the outermost LED clusters are populated. The LEDs have a warm colour temperature, which is a close match to the SON lighting of the remaining Trafficvisions.
A "Smart:iD" QR code label is attached to the underside of the V-Max; according to the text to the right of the label, this should be scanned for service.
The single-arm column, also on the southbound carriageway, featuring the other replaced lantern emerges from the trees on the embankment.
The retention chain system is demonstrated more clearly here, as is the adaptor that accommodates the narrower bracket into the lantern's wider receptacle.
