The Maxi 900 is a 900 mm surface-mounted bollard in 316 stainless steel, finished inpoly powder coated black, with a frosted diffuser running the head. This page sellstwo electrically different fittings at one price, and the drop-down asks you to choosebetween them by part number rather than by colour.

240 V or 12 V decide this before anything else

HV1608T-BLK-240V runs on 240 V AC mains and takes a9 W E27 globe, giving 700 lm / 720 lm / 740 lm. It isProtection Class 1 and requires an earth Havit’s own sequence isearth first, then live and neutral. HV1608T-BLK-12V runs on 12 V DCfrom a suitable 12 V DC LED driver, takes a 5 W MR16 globe and gives270 lm / 285 lm / 300 lm. It is Class 3 and needs no earth. Do notconnect the 12 V fitting directly to 240 V. The two are not interchangeable after the fact, because thelamp holder itself differs.

Two warranty conditions that only apply to the 12 V version

Havit’s low-voltage clause is a warranty condition, not advice: the voltage arriving at the fittingmust be within 5% of the rated figure, and the fitting must sit no more than25 m from its LED driver. Both are easy to breach on a long garden run, and both are reasonsto size the driver and the cable before you dig. Where several fittings share one driver they are wiredin parallel. Havit lists its HV9507 and HV9508tri-colour MR16 LED drivers against this range.

The globe, and the ceiling on what you may fit

Both versions take a replaceable globe, so the light is only as good as the lamp in it. Colourtemperature is tri-colour 3000K, 4000K or 5500K and it is set on the globe itself:the cover twists off anti-clockwise and the switch is on the side of the globe. The supplied globes are120, but a replacement sets its own beam, so check the beam angle of anything you buy. The ceilingmatters: Havit gives a maximum globe wattage of 15 W, LED globes only. That is a hardlimit on a sealed fitting and it rules out an incandescent or halogen lamp of any wattage. Neitherversion is dimmable with the globes supplied.

Getting it into the ground, and keeping the warranty

It is surface mounted: 900 mm tall, 102 mm, on a98 mm base plate with four 6 mm fixing holes and a16 mm cable entry. That plate must go onto concrete or a concrete pad, and the fittingmust never sit below finished ground level. Every hole including the cable entry is siliconed, andsilicone is run around the fitting at ground level Havit voids the warranty if this is not done. Allo-rings and seals must be in place. HV1607 is Havit’s optional spike if you wouldrather push it into soil than bolt it down. The body is 316 stainless, so it still needsregular cleaning maintenance; tea staining is not covered by warranty.Lights For You publishes these figures for HV1608T-BLK from the HV1608 APR24 data sheet, Havit’s 12 Vand 240 V installation instructions and the supplier’s own page for each of its two part numbers, withHavit’s 3 Years Replacement warranty on items ordered after 01/01/22.

Questions

Which one do I actually need, the 240 V or the 12 V?

If the bollard is being wired into mains by an electrician on a normal outdoor circuit, take HV1608T-BLK-240V it needs no driver and no transformer, and it must be earthed. If you are running a low-voltage garden system, or the bollard is one of several on a single driver, take HV1608T-BLK-12V. The 12 V version is the one bound by the 5% supply tolerance and the 25 m driver distance.

What globe does it take, and can I fit a brighter one?

The 240 V version takes a 9 W E27 and the 12 V version a 5 W MR16. You can replace either, but Havit caps the fitting at a maximum globe wattage of 15 W and LED globes only. There is headroom above the supplied lamp, and no headroom at all for a halogen or incandescent.

How do I change the colour temperature?

It is on the globe, not on the fitting. The cover twists off anti-clockwise and there is a switch on the side of the globe for 3000K, 4000K or 5500K. It ships set to 3000K.

Can it be dimmed?

Not with the globes supplied Havit states Dimmable: No not with supplied globes. The wording matters: the obstacle is the lamp rather than the fitting, so the honest answer is that Havit does not warrant dimming on this fitting as sold, and we are not going to promise it will work with a dimmable globe substituted.

Does it need an earth?

The 240 V version does it is Protection Class 1 and Havit’s wiring step is earth first, then live and neutral. The 12 V DC version is Class 3 and requires no earth.

Can I push it into the ground instead of bolting it down?

Only with Havit’s HV1607 optional spike. As supplied it is surface mounted, and the base plate must be fixed to concrete or a concrete pad. Havit is explicit that the fitting must not be installed below finished ground level, and that every hole must be siliconed both are warranty conditions.

What is the warranty, and does the black finish change it?

3 Years Replacement on items ordered after 01/01/2022. The finish does not change it, but the material obligation still applies: the body underneath is 316 stainless steel and needs regular cleaning maintenance, and tea staining is not covered.
