Simmonsigns Simbol

This is the most up-to-date bollard in the Collection; the distinctive shape of its shell being specifically designed to withstand vehicular collisions by flexing with the impact. By 2011, the Simbol was a common sight throughout the UK, including Derby, although it was still a relatively uncommon sight in the City when this example entered the Collection in 2005, following its successful purchase on eBay.

The Simbol is unusually shaped, in order to allow each face to round off towards the top and bottom. If a 'Keep Left' (for example) graphic were applied, it would normally be above the reflector strip on the front, though I think that a graphic can be applied to each face if specially requested.

The 'back' of the bollard is free of any graphics, but again, there may be the option of having them printed onto here as well.

The Simmonsigns symbol is on the front of the Simbol!

A base-light unit for the bollard was found and was then fitted to the shell on Thursday, 30th March 2006. The unit is made by rival firm Haldo; however, most shells are compatible with most base-lights, and so this was not a problem. The unit consists of an aluminium box with a gear tray unit fitted internally - this example takes two 11 Watt PL-S lamps; however, other variations include three 11 Watt lamps, three 8 Watt fluorescent lamps or even (more recently) white LEDs. This latter illumination method became standard for base lights only a few years later. Access to the lamps is gained by unscrewing the two tri-head bolts in either corner, and then removing the lid and lens. In normal operation, these units are obviously very close to the ground; thus, they are usually rated to a minimum ingress protection rating of IP67.

The gear tray can also be removed - this simply lifts out by pulling on the two nylon cords on either side. As this example only uses two lamps, the centre reflector section is not used.

With the tray removed, the rest of the base light can be seen - there is a cable entry gland and a small piece of wood where a cutout could be fitted.

The two lamps emitted a fair amount of light when powered up - certainly enough to light the inside of the shell anyway.

The shell is secured to the base light with four bolts - one in each corner. The Triplex Traffic HE65 bollard alongside is dwarfed by the Simbol's new height!

The light distribution in the shell was quite consistent for its entire length - though obviously the higher parts are a little dimmer.

Later, the Simbol shell was swapped over to the Signature 'Superior' base-light that had been used to up-light the Haldo 'Ecco' bollard shell; the thinking being that this would create a complete Haldo setup. To complement the Simbol, a Simmonsigns-branded desk clock is placed on top of it!


By 2020, LED retrofit lamps were available that fitted directly into G23 lampholders and ran without needing to remove the ballast; thus, the 11 Watt compact fluorescent lamps were substituted by 6 Watt LED equivalents instead. The only modification made to the wiring was to disconnect the Power Factor Correction capacitor.

Testing with my energy monitoring device revealed the following results:

Test Voltage (V) Current being drawn at full power (A) Measured wattage (W) Apparent Power (VA) Frequency (Hz) Power Factor True Power (W) Difference to rated wattage (2 6 Watt) Percentage Difference
