The smallest Dugo, and the only one in the range that is not a mains fitting: a 25mm aluminium column 281mm tall in white powder coat, with a 1.5W LED at each end. It is the quiet member of the family where the 5W model lights a two-storey faade, this one puts a discreet mark on a garden wall, a step-side pier or a run of fence posts.

It is an extra-low-voltage fitting, and the driver is part of the job

The Dugo 1.5W runs at 24V DC. Havit’s instruction is specific: use only a suitable 24V DC constant-voltage LED driver. The driver is what sits between the 240V supply and the light, and it must be sized above the combined load of everything on the run each fitting is 3W in total, so ten of them is 30W before any headroom. The fitting itself must never see anything but 24V DC. Cable length matters too at this voltage: a long run drops volts, and the far fitting dims before anyone works out why, so let your electrician size the cable rather than assuming.

What you get for 3 W

Output is quoted per head: 2 85lm, 2 95lm or 2 90lm by colour setting 4000K is the brightest, 5500K sits just below it and 3000K is the lowest. That is deliberately modest. Through a 36 beam it produces two small, sharp cones rather than a glow, which at this output is exactly right: a row of them at 23m spacing reads as a designed rhythm, where one on its own barely registers. Buy several or buy the larger model.

Rating and installation

It is IP65 and IK08, and because it is extra-low-voltage it is Protection Class 3 no earth is required at the fitting, unlike the 3W and 5W Dugo, which are Class 1. Havit specifies it as not dimmable, and a dimmer on the low-voltage side of a driver will not control it correctly in any case. A matching backing plate and stainless grub screws are supplied, and the plate is the drilling template. It is rated indoor or outdoor but for wall mounting only never in-ground or submerged. Warranty is 3 years replacement. Lights For You stocks the whole Dugo range, so a garden run of these can share a language with the larger mains fittings at the entry.

Questions

What driver do I need?

A 24V DC constant-voltage LED driver Havit names that type specifically. Size it above the total load of every fitting on the run; each Dugo 1.5W is 3W in total, so count the fittings and leave headroom rather than running the driver at its limit.

Can I wire it straight to the house supply?

No. It is an extra-low-voltage fitting and must be fed from a 24V DC driver. Connecting it to the 240V supply directly will destroy the LED and void the warranty.

Does it need an earth?

No. It is Protection Class 3, the class for separated extra-low-voltage equipment, so no earth is required at the fitting. Note that the 3W and 5W Dugo are Class 1 and do need one the range is not consistent on this point.

Which colour setting is brightest?

4000K, at 2 95lm, with 5500K at 2 90lm and 3000K at 2 85lm. The differences are small; set every fitting in a run to the same value, because a mismatch along a wall is far more visible than 10lm.

Is it bright enough on its own?

Not really, and that is by design. At 2 8595lm it is an accent. It works as a repeated element several at 23m spacing along a wall or fence. For a single fitting that has to do a job, use the 3W or 5W Dugo.

Why does the far light look dimmer than the first one?

Almost always voltage drop over a long low-voltage cable run. It is a cable-sizing question rather than a fault, and your electrician can calculate the right conductor size for the length and the total load.

Can it be dimmed?

No. Havit specifies it as non-dimmable, and putting a dimmer between the driver and the fittings will not control them properly regardless.
