The Prisma 970 is a 970 mm surface-mounted bollard with a replaceable E27 globe, inpowder-coated black aluminium behind a UV-stabilised Perspex diffuser. The taller post puts the lightsource above low planting, and because it takes a lamp rather than a sealed LED you can change the outputand the colour later.

240 V mains, earthed, and installed by an electrician

It runs on 240 V AC mains and is Protection Class 1, so itrequires an earth. Havit’s installation sheet leads with a warning rather than aspecification: this is a 240 V mains-voltage fitting, and in Australia and New Zealand fixed mainswiring must be carried out by a licensed electrician. There is no transformer and no driver in thisproduct. If you encounter a low-voltage input quoted against this model anywhere, disregard it theordering table, the protection class, the installation warning and Havit’s own product page all give240 V AC.

What the globe gives you, and what you may replace it with

It ships with an 8 W E27 LED filament globe at 2700K, giving700 lm across a 120 spread. Those figures describethat globe and not the fitting, so anything you fit later sets its own output and beam.It is not a tri-colour fitting: there is no switch and no colour-temperature setting, andthe way to change the colour is to change the lamp. Havit lists HV9569W at 2700K,HV9569N at 4000K and HV9569C at 5500K for exactly that. The socketaccepts up to 40 W, which is real headroom over the 8 W supplied, and the fitting isTriac dimmable stated on both Havit documents for this model, and possible only becauseit is a mains lamp holder rather than a sealed LED.

Ratings, and the limit IP65 does not cover

The body is IP65 and IK08. Colour quality isCRI >80 with SDCM <6, glare is UGR <39, andHavit rates lamp expectancy at >30,000hrs. One restriction is easy to breach withoutmeaning to: avoid direct high-pressure water exposure from pressure washers or irrigationsystems. IP65 is a jet rating rather than a pressure-wash rating, and a sprinkler head aimed atthe bollard is the usual way water gets in.

Installation and siting

It is surface mounted: the base plate fixes to concrete or a concretepad, and the fitting must not be installed under ground level. All seals,gaskets and cable entries must be correctly installed to maintain the IP rating. On siting, Havit’s wordingis that aluminium fittings should not be installed within 5 km of saltwater environments,and this fitting is aluminium. Lights For You publishes these figures for HV1642W-BLK from theHV1641W/HV1642W data sheet, the HV1641W/HV1642W installationinstructions and Havit’s own page for this model, which states a 3 Years ReplacementWarranty.

Questions

Is this a low-voltage bollard?

No 240 V AC mains, Protection Class 1, earthed, and wired by a licensed electrician. Havit’s installation sheet opens with that warning. There is no transformer or driver involved.

Can I change the colour temperature?

Not with a switch. This is not a tri-colour fitting; you change the globe. It ships at 2700K and Havit lists HV9569W (2700K), HV9569N (4000K) and HV9569C (5500K) E27 filament globes.

What is the maximum globe I can fit?

40 W is Havit’s ceiling for the socket. The supplied lamp is 8 W, so there is plenty of headroom, and the lumen and beam figures on this page describe the supplied globe rather than a replacement.

Can it be dimmed?

Yes Triac dimmable on both of Havit’s documents for this model. It is only possible because this is a mains E27 lamp holder. Check that the replacement globe is itself dimmable, since the lamp is half of the equation.

Why choose the taller one?

Height changes where the light sits relative to planting and to eye line rather than how much of it there is. The globe is the same, so the output is the same; the taller post lifts the source clear of low shrubs and spreads its 120 wash over more ground.

Can I pressure-wash it or site it near sprinklers?

No. It is IP65, but Havit explicitly says to avoid direct high-pressure water exposure from pressure washers or irrigation systems. IP65 covers jets rather than pressure washing, and irrigation aimed at the fitting is the common cause of ingress.

Can I use it near the coast?

Havit states that aluminium fittings should not be installed within 5 km of saltwater environments, and this bollard is aluminium. The wording is “should not” rather than “must not”, but nearer the sea you should be looking at 316 stainless instead.
