The Prisma 670 is a 670 mm surface-mounted bollard that takes a replaceable E27 globe,in powder-coated black aluminium behind a UV-stabilised Perspex diffuser. That lamp holder is whatseparates it from most bollards in this range: nothing here is sealed in for life, and the light you get isthe globe you choose.

240 V mains and Havit is emphatic about it

It runs on 240 V AC mains. It is Protection Class 1 andrequires an earth, and Havit’s installation sheet opens 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 anywherein this product. If you have seen a low-voltage figure quoted against this model, disregard it: theinput is 240 V AC, which is what the ordering table, the protection class, the installation warning andHavit’s own product page all state.

The globe decides the light including its colour

It ships with an 8 W E27 LED filament globe at 2700K, giving700 lm over a 120 spread. Those three figures belong tothat globe, not to the fitting, so a replacement sets its own output and its own beam.This is not a tri-colour fitting there is no switch and no colour-temperature setting.If you want cooler light you change the lamp, and Havit sells the alternatives for exactly this:HV9569W at 2700K, HV9569N at 4000K and HV9569C at5500K, all E27 filament globes. The ceiling matters when you go shopping: the socket accepts up to40 W, so there is real headroom above the 8 W supplied, and the fitting isTriac dimmable stated on both of Havit’s documents for this model, which is unusual inthis range and only possible because it is a mains lamp holder.

Ratings, and one limit IP65 does not cover

The body is IP65 and IK08. Colour quality isCRI >80 with SDCM <6, glare is UGR <39, andlamp expectancy is >30,000hrs. Havit adds a restriction worth reading before yousite it: avoid direct high-pressure water exposure from pressure washers or irrigationsystems. IP65 is a jet rating, not a pressure-wash rating, and an irrigation head pointedstraight at a bollard is the usual way that gets breached.

Installation and siting

It is surface mounted: the base plate must be fixed to concrete or a concretepad and the fitting must not be installed under ground level. All seals, gasketsand cable entries have to be correctly installed to maintain the IP rating. On siting, Havit’s wording isthat aluminium fittings should not be installed within 5 km of saltwater environments,and this fitting is aluminium. Lights For You publishes these figures for HV1641W-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. It is 240 V AC mains, Protection Class 1, and it must be earthed and wired by a licensed electrician. Havit’s installation sheet says so in a warning at the top. There is no transformer or driver in this product at all.

Can I change the colour temperature?

Not with a switch there isn’t one, and 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 as the alternatives.

What is the biggest globe I can fit?

Havit gives a maximum wattage of 40 W for the socket. The supplied lamp is 8 W, so there is substantial headroom but 40 W is the limit, and the lumen and beam figures on this page describe the 8 W globe as supplied rather than anything you fit later.

Can it be dimmed?

Yes Triac dimmable, stated on both Havit documents for this model. That is unusual for a bollard in this range and it is only possible because it is a mains E27 lamp holder rather than a sealed LED. Whether you actually get smooth dimming also depends on the globe you fit, so check that the replacement lamp is itself dimmable.

Is it bright enough for a path?

The supplied globe gives 700 lm at 2700K over a 120 spread, which is a warm, wide wash rather than a directed beam. If you want more you have headroom to 40 W; if you want cooler, change the globe.

Can I hose it down or use it near irrigation?

Careful here. It is IP65, but Havit explicitly says to avoid direct high-pressure water exposure from pressure washers or irrigation systems. IP65 covers jets, not pressure washing, and a sprinkler aimed at the fitting is the common cause of water ingress.

Can I use it near the coast?

Havit’s wording is that aluminium fittings should not be installed within 5 km of saltwater environments, and this bollard is aluminium. Note that Havit says “should not” rather than “must not” here, but the intent is clear and closer to the sea you should be specifying 316 stainless.
