The SL-GR1D-1/3W mini pathway underground light is a compact recessed fixture family for marking walkways, deck edges, planting borders and low facade details. The 2026 outdoor catalog defines three 1W A-version sizes with open single-beam apertures and one 3W B version with a shielded multi-opening cover. The current page gallery instead combines the A-style single lens with an open triple-lens 3W body, so the exact 3W construction must be confirmed before the page is treated as a final product specification.
Variant Correction: Model SL-GR1D-1/3W is listed on page 56 of the 2026 outdoor catalog, but the target gallery does not fully match its A/B structure. Catalog A covers 1W in D42, D52 and D62mm bodies. Catalog B is a 3W D75mm shielded multi-opening fixture. The page gallery shows a D75mm open triple-lens unit instead. Confirm whether that unit is a current unlisted variant, an old revision or a mismatched image.
Key Difference: This URL is an older mixed entry inside the Mini Underground Light category. Page 62622430 is the stronger single-beam pathway master for the same model and category, while 63178559 should represent the shielded multi-hole B variant only if its ERP code is confirmed. The cleanest structure is to migrate useful imagery and redirect 62622419, 62622440 and 62622447 to 62622430.
Three 1W Diameters
D42, D52 and D62mm A bodies support different paving and detail scales.
3W Shielded B Version
The catalog shows a D75mm hooded cover for decorative low-glare patterns.
Five Catalog Beams
8, 15, 30, 45 and 60-degree optics cover narrow accents through wider pools.
IP65 Outdoor Rating
Current catalog and gallery evidence support IP65, not submersible use.
Aluminum Body
The catalog specifies an aluminum housing; the metallic trim grade requires BOM confirmation.
High or Low Voltage
Catalog and gallery sources list mains and 12-24V configurations as separate versions.
Flush Embedded Mounting
A pre-buried sleeve coordinates the fixture with paving, deck or concrete surfaces.
On-Off Control
The 2026 table marks these variants on-off only; dimming requires separate evidence.

Specification boundary: IP65 does not permit permanent immersion. The catalog does not list DALI, 0/1-10V or Triac for this model. Static red, green and blue options do not establish RGB color-changing or DMX control. Certification icons require model-specific documents.
| Catalog Version | Power | Size | Optical Form |
|---|---|---|---|
| A | 1W | D42 x H73mm | Open single beam |
| A | 1W | D52 x H82mm | Open single beam |
| A | 1W | D62 x H88mm | Open single beam |
| B | 3W | D75 x H98mm | Shielded multi-opening cover |
The fixture diameter and height form one approved body, not interchangeable dimensions. The target gallery's D75 x H98mm triple-lens open face is not the B cover pictured in the 2026 catalog. Do not quote it as the standard B version until the factory maps that gallery image to an active item code.
The open A version produces a compact upward beam from a small circular trim. It can mark a pathway rhythm, illuminate the base of a low wall or add a discreet point of light near planting. The three diameters let a specifier coordinate the visible trim with paving joints and material scale while keeping the same 1W electrical load.
Use the 8 or 15-degree optic for a narrow vertical accent, 30 degrees for a focused pool, and 45 or 60 degrees where a softer spread is required. Final spacing depends on mounting depth, target distance and photometric performance. Request the IES or LDT file rather than estimating beam coverage from a marketing image.
The 2026 catalog B version uses a sculpted cover with several lateral openings. This changes the product from a conventional open uplight into a low-level decorative marker that sends controlled light across the surrounding surface. It suits deck edges, paths and plazas where the pattern matters more than vertical wall washing.
Page 63178559 should own the multi-hole search intent only if its gallery and ERP record are updated to match this catalog B construction. If the page continues to show a different one-to-four-hole family, treat that as a separate variant conflict rather than using it as proof for the B version.
The current catalog and gallery identify IP65. This supports a dust-protected enclosure and resistance to water jets when the fixture, gland, seals and external connection are correctly assembled. IP65 does not certify temporary submersion, continuous immersion, pool installation or fountain use.
Remove the page's IP67/IP68 and one-meter-submersion claims unless a newer IEC 60529 report covers the exact SKU. Keep the junction out of standing water and provide drainage around the sleeve. Pool chemicals, coastal corrosion and vehicle loading require separate material, sealing and mechanical evidence.
The gallery shows an eight-step embedded installation with a plastic pre-buried body. The sleeve is positioned flush with the finished surface, the cable passes through its wire opening, and the luminaire body is lowered into place after the surrounding material is completed. This approach separates civil preparation from final fixture installation.
The illustration does not establish drainage capacity, load rating or safe installation in every substrate. Provide a free-draining base, prevent the sleeve from becoming a water cup and seal the cable connection with an appropriate outdoor method. Confirm cutout, sleeve dimensions, cable bend radius and maintenance clearance from the approved drawing before concrete or paving is poured.
The page gallery lists AC100-265V or AC/DC12-24V, while the printed catalog appears to state AC220-265V or AC/DC12-24V. Treat the high-voltage range as unresolved until the driver label and SKU list are checked. Low-voltage and mains versions require different wiring, protection and installation practices.
The 2026 model table marks all four variants on-off only. Remove the page's generic Support Dimming field and old 0-10V/Triac language unless a driver sheet proves those options. A separate gallery drawing shows a DMX512 RGB wiring concept, but that generic diagram does not prove the standard SL-GR1D-1/3W configuration supports DMX.
Pathway markers - repeat the compact A version at a measured spacing to define movement without tall fixtures.
Deck and terrace edges - coordinate the trim diameter with board joints and keep water from collecting around the sleeve.
Low wall accents - use a focused optic to create a small vertical pool from close range.
Planting borders - position the beam away from direct eye lines and protect the cable from maintenance tools.
Hotel courtyards - use one verified finish and CCT bin across repeated fixtures for visual consistency.
Decorative ground patterns - use the confirmed B cover where lateral light patterns are required.
Specify model, A or B cover, power, diameter and height, beam angle, CCT or static color, voltage, control, trim material, sleeve, cable, quantity and destination market. Request the approved drawing, IES/LDT file, driver label, IP65 report, efficacy and CRI data, material BOM, load test if required, warranty and model-specific certificates.

Migrate unique images, video and any useful copy from 62622419, 62622440 and 62622447 into 62622430, update internal links, then apply permanent redirects. Keep 63178559 only if the factory confirms a distinct B cover and supplies matching photography; otherwise merge it as well. The cross-category 62622437 page must retain a different engineering-document intent.
Is SL-GR1D-1/3W in the 2026 catalog? Yes. The exact model is listed on page 56 of the 2026 outdoor catalog.
What is the difference between A and B? A is the open single-beam 1W family in three diameters. B is a 3W D75mm shielded multi-opening version.
Is the target page's triple-lens 3W fixture the catalog B version? No direct evidence proves that mapping. Its open face differs from the hooded B product image, so the item code needs confirmation.
Can the light be installed underwater? No claim should be made from the current IP65 source. Use a purpose-built underwater luminaire for submerged applications.
Does the product support dimming or DMX? The catalog marks on-off only. Dimming and DMX require a separate approved driver and wiring specification.
Which page should remain in the Mini Underground Light category? Page 62622430 is the recommended single-beam master. The weaker same-category pages should redirect to it.
What information is required for an RFQ? Provide A/B version, power, size, beam, CCT or color, voltage, control, trim and sleeve materials, cable, quantity and destination market, then request matching technical files.
