Essil Up & Down LED Wall Light

The HV3649T is the larger Essil — the same slim rectangular up-and-down wall light in poly powder coated aluminium, stepped up to 2 × 6 W and roughly twice the output of the compact HV3646T. Two built-in LED emitters wash a wide 120° spread up the wall and down it. Specify it where the wall is tall, the spacing is generous, or an entry needs real presence.

The supply decides the wiring — and the dimming

Four variants: black or white, each in 240 V AC or 12 V DC. The 240 V version wires straight to mains and is Class 1, so an earth is required. The 12 V version needs an external 12 V DC LED driver, which is not supplied, and Havit warns in capitals that the fitting must not be connected directly to 240 V; it is Class 3, so no earth is needed. Wire several on one run in parallel.

Dimming is available on the 240 V variants only

This is the difference that catches people out. The 240 V variants are Triac dimmable; the 12 V variants are not dimmable. Havit states the split three separate ways — the data sheet, the installation sheet’s per-model table and its own product copy — and it cannot be reversed once the wall is closed up. If the light has to dim, choose the 240 V variant.

Two emitters, and every lumen figure is per direction

Havit publishes the output as 2 × 350 lm at 3000K, 2 × 365 lm at 4000K and 2 × 380 lm at 5500K — per direction, meaning what one emitter delivers, produced twice by the fitting. Power reads the same way: 2 × 6 W, or 12 W total. We publish the per-emitter figure with the count, because a summed number hides how much light reaches the wall in each direction.

5500K is the brightest, and that is worth checking per fitting

Output rises with colour temperature here: 5500K is the brightest at 380 lm per direction, 4000K sits at 365 lm and 3000K is the dimmest at 350 lm. Thirty lumens separate the ends. We state it per product because the assumption is not safe in general: several fittings in the same range are brightest in the middle.

Colour is set once, inside the fitting

It is tri-colour — 3000K, 4000K or 5500K — on a slide switch inside the base, shipped preset to 3000K. Changing it means lifting the body off its base plate. The beam is a fixed 120° and is not adjustable.

The seal is what the warranty rests on

Run the cable through the cable gland, seal every hole including the cable entry and around the screws, tighten the allen screws, and apply silicone around the edge of the fitting. Every o-ring and seal must be correctly seated to maintain the warranty, and modifying the fitting voids it. It is IP54 behind a glass diffuser with an IK08 impact rating.

Siting, and what the drawing leaves out

The Essil is aluminium, and Havit states that aluminium and 304SS fittings must not be installed within 5 km of any salt water environment — for a beachside address, ask us for a marine-grade option instead. It mounts on a base plate taking four Ø5 mm fixings around a Ø17 mm cable entry. Havit’s drawing prints the body’s overall figures without labelling which is which, so we publish no overall dimensions and no wall projection and point you to the dimensioned drawing instead. At Lights For You we stock both Essil sizes in black and white on both supplies, and will size a driver with you.
