Metro Round 316 Stainless Steel RGBW

The Metro RGBW is a colour-changing recessed inground uplighter with a 316 stainless steel cover on an aluminium body, and this listing sells the round part, HV1801RGBW. It sits in a canister below ground level and finishes flush behind clear glass. Havit rates it trafficable to 600 kg, IP65 and IK10.

It is a sealed built-in LED — there is no globe in this one

⛔ Unlike the tri-colour Metro, this model has no lamp base and no socket. The 1 x 5 W RGBW LED is integral and produces 255 lm at 3000K in white at CRI >80. RGBW is the three colour channels plus a dedicated 3000K white channel, so warm white is a real channel rather than a mix.

You need two things behind it, not one

It is a 12 V DC constant-voltage fitting and it is Protection Class III — low voltage, no earth required. ⛔ It must not be connected directly to 240 V. Havit's wiring diagram runs fitting → RGBW controller → 12 V DC LED driver, so plan on both a suitable 12 V DC LED driver and a compatible RGBW controller. ⚠ The controller is also what dims it: Havit records the fitting as dimmable with an RGBW controller and not otherwise. Runs are wired in parallel, the tail is colour-coded, and the supply at each fitting must stay within ±5% of rated or the warranty is void.

The hole, the drainage and the warranty conditions

Havit's drawing gives the cutout as Ø110 mm with the canister and Ø100 mm without, with a Ø120 mm face and a 155 mm canister. ⛔ Drainage is a warranty condition — a 100 mm space beneath the canister and 100–150 mm of crushed rock under that — and the canister must finish level with the ground or floor or the warranty is void. Joins are soldered and covered watertight, every o-ring and seal seated, the cable gland tightened before the fitting is inserted, and silicone run around the edge. ⚠ With no globe to change, none of that needs undoing later.

Where it should not go

⚠ Havit's current installation sheet restricts aluminium and 304 stainless steel fittings to no closer than 5 km from salt water, and this fitting's body is aluminium under a 316 stainless cover. ⚠ Tea staining on 316 stainless is not covered by the warranty, so clean the cover regularly. Published lamp expectancy is >30,000hrs; the warranty is 3 Years Replacement.

Lights For You can pair this with the controller and driver that suit the size of your run — worth a conversation before the trench is dug rather than after.
