SL-GR1H Floor Recessed Thin Ground Light LED Underground Lamp | Ultra-Slim Inground Uplight 3W 18W Five Sizes 8 Colors RGB IP67 Waterproof Stainless Steel Tempered Glass 8° 15° 30° 45° 60° Beam AC/DC12-24V for Pathway Driveway Garden and Facade

The SL-GR1H floor recessed thin ground light is an ultra-slim, low-profile LED underground lamp engineered for flush installation in pavement, tile and concrete. Five power ratings from 3W to 18W span five diameters from 100mm to 210mm, in eight light colors including RGB. A brushed stainless steel trim with tempered glass cover shrugs off weather and foot traffic, while the IP67 waterproof construction - sealed with a waterproof nut and aluminum gland - keeps the COB source dry through rain, sprinklers and seasonal changes. This makes it a reliable choice for pathways, driveways, gardens, plazas and building facades.

Key Difference: This is the thin/ultra-slim member of the Synno LED underground light family. With only 55mm of installed height, five diameters from 100mm to 210mm, eight color options including RGB, and IP67 protection, one SL-GR1H series covers step lights, driveway markers, tree uplights and facade accent lines - all in one flush-mounted footprint. Low-voltage AC/DC12-24V wiring keeps installation safe and simple.

IP67 Waterproof & Eight Color Options

The SL-GR1H is sealed to IP67 with a waterproof nut and aluminum gland, keeping moisture and dust out of the housing through rain, sprinklers and winter weather. Inside, a COB or LED light source delivers uniform, high-color-rendering light with no visible spot, and the brushed stainless steel trim resists corrosion while the tempered glass cover offers high impact resistance and optical clarity. Eight colors - white, yellow, cold white, RGB, blue, red, warm white and green - let you match any landscape scheme, with lamp beads customizable from CREE, OSRAM Opto Semiconductors, EPISTAR, Bridgelux and LUMINUS at 3000K, 4000K or 6000K.

Eight-Step Installation & Low-Voltage Wiring

Installation follows a simple eight-step guide: switch the circuit breaker off, secure the embedded sleeve, fix the three screws, thread the power cord through the wire hole, lower the lamp body into the plastic embedded body, complete the flush mount, and switch the breaker back on. The system uses low-voltage DC12/24V wiring with an AC100-265V input driver; connect fixtures in parallel with brown to L and blue to N, use terminal blocks or waterproof tape reinforced with electrical tape, and always check the connection before powering on.

Typical Applications

Walkways & driveways - flush step light and path guidance.

Gardens & patios - ambient accent light in beds and borders.

Plazas & courtyards - heavy-load fixtures safe to walk over.

Building facades - vertical accent columns of light.

Tree uplighting - narrow 8-15 degree beams for trunks and canopies.
