Siena LED Up and Down Wall Light CCT 9w Black, White Havit Lighting - HV3655T

The Siena is Havit’s slim rectangular up-and-down wall light in poly powder coated aluminium, and the HV3655T is the compact 162 mm size. Two built-in LED emitters throw a soft 120° wash up the wall and down it, so what you see is a lit surface rather than a bright fitting — the reason this shape ends up either side of a front door, along a rendered fence or up a pier.

Two emitters, and the figures below are per direction

Havit prints this fitting’s output as 2 × 255 lm at 3000K, 2 × 265 lm at 4000K and 2 × 260 lm at 5500K. Those are per direction — each figure is what one emitter delivers, and the fitting produces that twice. The same applies to the wattage: the listing is titled 9 W because that is the total, while the data sheet says 2 × 4.5 W. Both are true and they count different things, so we state the per-lamp draw and the emitter count rather than letting a single number imply a 9 W emitter.

4000K is the brightest, not 5500K

This matters because the natural assumption runs the other way. Output on the Siena peaks in the middle: 4000K is the brightest setting at 265 lm per direction, with 5500K slightly behind at 260 lm and 3000K the dimmest at 255 lm. The spread is small — ten lumens either side — so choose the colour you want the wall to look, not the one you assume is brightest.

You set the colour once, from inside the fitting

It is a tri-colour fitting: 3000K, 4000K or 5500K, selected on a slide switch inside the base. Havit ships it preset to 3000K, and changing it means loosening the allen screws and lifting the fitting off its base plate. That makes it a decision taken on the ladder at install rather than adjusted later from the ground.

Sealing it is a warranty condition, not a suggestion

Havit’s instructions are specific: seal all holes including the cable entry and around the screws, tighten the allen screws so water cannot penetrate, and apply silicone around the edge of the fitting. All o-rings and seals must be correctly in place to maintain the warranty, and modification voids it. The fitting is IP54 with a frosted glass diffuser and an IK08 impact rating; those ratings assume the install was sealed. It runs on 240 V mains — no driver or transformer — and is Class 1, so an earth is required.

Where it can go, and how big it is

This is the aluminium Siena, and Havit states that aluminium and 304SS fittings must not be installed within 5 km of any salt water environment. For a coastal address, ask us for a marine-grade alternative rather than specifying this one. The body is 162 mm long and 72 mm wide, on a base plate taking two Ø4 mm fixings around a Ø13 mm cable entry. Havit’s drawing does not label its remaining dimension, so we do not publish a wall projection — the dimensioned drawing sits in the data sheet on this page. It is Triac dimmable, and Havit names the HV9625 300 W dial dimmer as its compatible accessory. Lights For You stocks both Siena sizes in both finishes, and we are glad to check spacing with you before you order.
