Klip LED Inground Light CCT 20w in 316 Stainless Steel Havit Lighting - HV1833T

At 20 W the Klip stops being something you slip into a garden bed and becomes a hole you have to plan. The cutout is Ø194 mm with the canister and the face on the surface is Ø210 mm — better than a fifth of a metre of finished paving or lawn. Get that decided before the landscaper pours anything, because retro-fitting it afterwards means breaking ground twice.

Plan the hole and the drainage together

Havit's requirement is a warranty term, not a recommendation: adequate drainage must be allowed to prevent fittings from sitting in water for a long period of time, and if no drainage is allowed the warranty will be voided. Below the canister it wants a 100 mm space, and beneath that 100 mm to 150 mm of crushed rock, with a slight fall on the finished ground so surface water runs away from the fitting rather than into it. The canister must finish level with the ground or the warranty is void. So the excavation is deeper than the fitting — allow for the canister, the void and the rock bed together. IP67 means it survives temporary immersion; it does not mean it can live in standing water.

What 20 W buys

Output is 1600 lm at 3000K, 1700 lm at 4000K and 1800 lm at 5500K across a 120° beam, from a built-in LED — no globe, no socket, nothing user-replaceable. That is roughly double the 10 W into the same wide spread, which is what carries the light up a two-storey wall or into a mature canopy rather than stopping at the first branches. Brightness rises with colour temperature, so 5500K is the brightest setting. Colour is selected on a switch under a sealed cap on the base, factory set to 3000K, and it is far easier to set before the fitting drops into the canister.

Two supplies, and they are wired differently

This listing sells HV1833T-12V and HV1833T-240V. The 12 V DC model is Class 3, requires no earth, and must run from a suitable 12 V DC LED driver — never directly off 240 V. At 20 W it is a substantial load on a shared low-voltage run, and Havit voids the warranty if the supply at the fitting falls outside ±5% of its rated voltage, so size the driver and the cable for it. The 240 V AC model is Class 1 and must be earthed, earth first. Fittings are wired in parallel.

Build and upkeep

316 stainless steel cover over a black aluminium body, IK10, and trafficable to 1000 kg. Havit asks for regular cleaning of all 316 stainless fittings to prevent tea staining and states that tea staining is not covered by warranty; the HV9971 kit is its recommended remedy. Lights For You has taken every figure above from the HV1833T data sheet and the HV1833T installation instructions. Havit's 3 Years Replacement warranty applies to items ordered after 01/01/2022.
