Synno Lighting Outdoor Inground Light Model SL-GR1C
2 year agoSL-GR1C Outdoor Underground Lamp Ground Light For Pathway Decoration | Multi Beam Dome Circular Deck Light 3W 5W 6W 7W 9W 12W One Way Two Way Four Way Cross Ring Radial Louver Covers Φ80 100 120 150 160 180 200mm IP65 AC100-265V DC12 24V RGB Stainless Steel Ring for Stair Deck Gravel and Paving
The SL-GR1C is a dome-topped underground ground light that spreads light horizontally instead of straight up. Six interchangeable opening patterns on the dome - a single window, opposite twin windows, a four-way cross, a ring of rectangular windows, radial slits or full vertical louvers - shape the beam into a one-way fan, a two-way wash, a four-way star or a 360-degree glow, letting one family of buried fixtures cover stair treads, wooden decks, gravel beds and paved walkways with exactly the light pattern each space needs.
Key Difference: This is the multi-beam dome ground light of the Synno underground family - six dome cover designs from one-way to 360-degree louvered glow, in powers from 3W to 12W and diameters from Φ80 to Φ200mm. Where the GR1E fires a fixed 60-degree uplight, the GR1M tilts its beam and the GR1L draws lines, the GR1C scatters horizontal light around a walkway, deck or stair with a soft, glare-free dome glow.

Multi-Beam Dome - Choose the Light Pattern
The dome is the soul of the GR1C. Each power step pairs with an opening design that shapes the light before it reaches the ground: the 3W single-hooded dome throws a focused one-way fan for directional accents; the 5W twin-window dome washes two opposite sides of a path; the 6W cross dome paints a four-point star on stair treads; the 7W ring-window dome glows evenly around a planter or bollard; and the 9W radial-slit and 12W louvered domes spread a full 360-degree glow for open areas. Because light leaves the dome horizontally, the fixture reads as a soft luminous cap rather than a blinding uplight - comfortable for eyes at deck and path level.
Seven Diameters, One Installation System
The range spans Φ80 to Φ200mm in diameters of 80, 100, 120, 150, 160, 180 and 200, with body heights of 95 to 125mm, so the same family scales from a subtle 3W path marker to a 12W deck statement. Installation uses the Synno eight-step routine: switch the breaker off, loosen the T-screws with an Allen key, separate the dome cover, glass and lamp body, place the plastic embedded body in cement with the power cord through the wire hole, lower the lamp in and connect it, refit the cover and lock the screws, then switch the breaker on. Later, maintenance is a simple lift-out of the lamp body - the embedded shell stays in the ground.
Colors, Materials & IP65 Weatherproofing
Light color is selectable in white, warm white, yellow, cold white, blue, red, green or RGB, powered by US Bridgelux LEDs (or a chip of your choice) with dimming support and a 50,000-hour life. A stainless steel trim ring guards the glass cover, the body is die-cast aluminum for heat dissipation and long-term durability, and every cable entry is sealed with an IP65 waterproof nut and aluminum gland - rain, sprinkler washdown and morning dew are no problem across the -20 to +40 degree working range.
Typical Applications
