The Nikki is a compact up/down exterior wall light in poly powder coated aluminium behind tempered glass, with a 10 W built-in LED throwing light in both directions. What separates it from most fittings this size is the beam: 120, which is wide. Instead of two tight blades of light on the wall it produces two broad soft washes that overlap into general illumination the right answer when you want a wall lit rather than decorated.

The choice to make

Finish only: HV3637T-BLK in black or HV3637T-WHT in white, at the same price and identical in every other respect. Colour temperature is set on the fitting at install across 3000K, 4000K and 5500K, with output rising as it cools 2 375 lm, 2 400 lm and 2 425 lm respectively. Those figures are per direction: each of the two apertures produces that output, which is how the fitting is specified and how it should be compared against a single-direction light.

Where it works

• Entry and courtyard walls under an eave, where the wide beam fills rather than stripes.
• Covered alfresco and verandah walls needing usable general light.
• Repeated along a sheltered passage, spaced so the washes overlap.
• Balcony soffits and protected stairwells.

Specifying it

The Nikki runs on 240 V AC and wires straight to mains, so there is no driver or transformer to allow for. The LED is built in: no globe is supplied because none is needed, nothing is relamped, and at end of life the fitting is replaced. It is not dimmable, so leave a dimmer off the circuit.

The rating decides where it may go. At IP54 it is protected against splashing water but not driving rain, so it belongs under an eave, soffit or balcony rather than on an exposed facade for a fully exposed position an IP65 fitting is the right specification and we stock several in this type. Like the rest of the Havit range it carries a 3-year replacement warranty. Lights For You can confirm current stock in either finish before you order a run of them.

Coastal siting Havits condition

Havits installation instructions for this fitting state that aluminium and 304 stainless steel fittings must not be installed within 5 km of any salt water environment. That is a condition on where the fitting may go, and it sits beside the IP rating rather than inside it: a fitting can be rated for direct rain and still fall outside this rule, because the issue is salt carried in the air rather than water landing on the surface. If your site is inside that zone, talk to us before you specify it Lights For You can point you at a fitting whose material Havit does not name here.

Earthing and protection class

This fitting runs on 240 V AC mains and is Protection Class 1 an earth is required at the fitting. Havit’s installation sheet has the installer connect the earth conductor first, then live and neutral.

Questions

Is the lumen figure per direction or for the whole fitting?

Per direction. It produces 2 375 lm at 3000K, 2 400 lm at 4000K and 2 425 lm at 5500K each of the two apertures gives that output.

Can it be mounted on an exposed wall?

No. It is IP54, which covers splashing only, so it needs an eave, soffit or balcony over it. An exposed position needs an IP65 fitting.

Does it need a driver?

No. It is 240 V AC and wires straight to mains.

What globe does it take?

None. The 10 W LED is built in, so there is nothing to buy with it and nothing to replace later.

Is it dimmable?

No. The datasheet states it is not.

What does the 120 beam mean in practice?

It spreads light broadly rather than throwing a tight blade up and down the wall. That suits general illumination and wide coverage; for a sharp architectural stripe, a narrow-beam up/down fitting is the better choice.

What warranty applies?

A 3-year replacement warranty.
