The Fedor Round at 925 mm is the tall version of the same fitting: polypowder-coated black aluminium, a sealed 12 W tri-colour built-in LED and a clearPerspex diffuser. Havit calls it a 1 directional bollard, throwing a60 spread through a single aperture rather than a glow all round. At close to a metreit clears low planting and puts the light source above ankle height, which is the usual reason to pickit over the 525 mm one.

The taller body does not buy you more light

This is the thing most people assume and it is not true here. Havit gives the 925 mm round exactlythe same figures as the 525 mm round 610 lm at 3000K, 620 lm at4000K, 615 lm at 5500K because it is the same 12 W engine on a longer post.What does change the output is the body shape: the square Fedor is brighter at the samewattage. So choose the height for reach and proportion, and the shape for brightness.

Two supplies on one listing

HV1631T-BLK-240V-RND is 240 V AC mains andProtection Class 1, wired with an earth, and Havit’s instructions connect the earthfirst. HV1631T-BLK-24V-RND is 24 V DC andProtection Class 3 no earth required running from a suitable24 V DC LED driver, with the supply at the fitting held within 5% ofthe voltage required or the warranty is void. Both are an electrician’s job toAS/NZS 3000, and multiple bollards on one circuit are wired inparallel.

Colour temperature, and the quality figures behind it

It ships set to 3000K. Loosen the allen screws on the side, lift the top off andmove the switch on the underside of the top to 3000K, 4000K or 5500K, then refit thetop with its seals properly seated. 4000K is the brightest of the three, so output doesnot climb with colour temperature. Colour rendering is CRI >80 withSDCM <5 and UGR <12, lamp expectancy is>30,000hrs, and the fitting is not dimmable.

Weather, impact and one siting rule

Sealing is IP65 and impact resistance is IK08 on the IK01IK10scale, which is worth having on a post this tall in an open garden. Havit states thataluminium and 304SS fittings must not be installed within 5 km of any salt waterenvironments, and this is an aluminium fitting, so that is a warranty condition on where itcan go.

Mounting, sealing and fixings

It is surface mounted: the base plate goes on concrete or a concretepad and the fitting must not be installed under ground level. Silicone everyhole including the cable entry, and around the fitting at ground level. Keep all o-rings and seals inplace, and fix the cable entry if your cable is not circular. The screws supplied aremild steel and should be replaced with a higher grade wherever water can reach them worth doing on a taller bollard that catches more wind load. Havit lists HV162X-CIanchor bolts as the accessory for these bollards. Every figure on this page for the 925 mm round Fedorwas taken by Lights For You from the Fedor Round data sheet, the shared installation instructions andHavit’s page for this model, which states a 3 Years Replacement Warranty.

Questions

Is the 925 mm brighter than the 525 mm?

No. Havit gives both round Fedors the same 12 W engine and the same figures 610 lm, 620 lm and 615 lm. Height changes reach and proportion, not output. The square Fedor is the brighter body.

What is the difference between the two part numbers?

The supply only. HV1631T-BLK-240V-RND is 240 V AC mains and Protection Class 1, so it needs an earth. HV1631T-BLK-24V-RND is 24 V DC, Protection Class 3 with no earth required, and needs a 24 V DC LED driver.

Can the 24 V version go straight onto mains?

No. Havit’s instruction is to use an appropriate 24 V DC LED driver and do not connect the light fitting direct to 240 V. The supply reaching the fitting must also stay within 5% of the voltage required.

Is there a globe in it?

No. It is a sealed built-in LED no lamp holder, no socket and no replacement lamp, so there is no maximum globe wattage to work to either.

How do I change the colour temperature?

Loosen the allen screws on the side of the fitting, lift the top off, and move the switch on the underside of the top to 3000K, 4000K or 5500K. Refit the top with the seals seated. It arrives set to 3000K.

Can I use it near the coast?

No. Havit states that aluminium and 304SS fittings must not be installed within 5 km of any salt water environments, and this bollard is aluminium. That is a warranty condition, not a recommendation.

Is it dimmable?

No. Both of Havit’s documents record this model as not dimmable, so wire it to a switched circuit.
