SMY Deck Lights FAQ: Hole Size, Spacing, Power, and Installation
Planning deck lighting is easier when you know the required hole size, cable reach, and installation layout before drilling. This buyer-focused FAQ covers the main points reported by SMY deck light users, including what worked well and what to check before ordering.
SMY Deck Light Details at a Glance
| Item | Reported detail | Buying or installation consideration |
|---|---|---|
| Drilled hole size | 7/8 inch | Use a 7/8-inch hole saw for the light openings. |
| Power per light | 0.6 watt | Offers a noticeable lighting effect with low individual power consumption. |
| Connections | Plug-together connectors | The connectors simplify assembly during installation. |
| Power supply | Compact unit with mounting holes | Plan a suitable mounting position when laying out the system. |
| Advertised cable length between lights | 1 meter | Usable spacing may be shorter after routing cable around or through deck joists. |
| Reported fascia spacing | 34 inches | One installer required cable extensions to achieve this spacing. |
| Common applications | Deck stairs and deck fascia | Include the lights and cable paths in the deck layout before drilling. |
Installation Planning Guide
1. Confirm the lighting positions
Decide where each light will sit before making any holes. SMY deck lights have been installed successfully on deck stairs and fascia boards, where they create a strong visual effect after dark.
2. Check the cable route—not only the straight-line distance
The stated distance between lights is 1 meter, but that does not always translate into 1 meter of practical fixture spacing. Cable routed through or around joists uses part of the available length.
For example, one installer placed lights 34 inches apart along the deck fascia but needed to extend the original cables to maintain that spacing. The extension was made using standard low-voltage lighting cable, butt splice connectors, and heat-shrink material.
3. Drill the mounting holes
A 7/8-inch hole saw is all that is reported to be necessary for the light openings. Mark every position first, then verify that there is enough clearance behind each location for the fixture and cable path.
4. Connect and position the components
The lights use plug-together connectors, making the lighting sections straightforward to join. The compact power supply also includes mounting holes, so its installation position should be considered as part of the initial layout.
How Bright Are SMY Deck Lights?
Users describe the lights as brighter than expected. Although each light is rated at 0.6 watt, the installed system can create a significant visual effect across deck stairs, fascia, and the surrounding backyard.
The result is especially noticeable after dark. Buyers looking for compact fixtures with low individual power consumption may find that the 1-watt output offers a good balance between fixture size and visible impact.
What to Check Before Buying
- Number of light positions: Count all planned stair, fascia, or deck mounting points.
- Hole-saw availability: Have a 7/8-inch hole saw ready for installation.
- Actual cable path: Measure around structural elements rather than relying only on the direct distance between lights.
- Desired spacing: Wider spacing may require additional low-voltage cable and suitable connection materials.
- Power-supply location: Allow space for the compact power supply and use its mounting holes when positioning it.
- Access behind the surface: Make sure cables can be routed behind the selected stair or fascia locations before drilling.
Frequently Asked Questions
What size hole should I drill for SMY deck lights?
Use a 7/8-inch hole saw. This is the reported hole size required for installing the lights.
How many watts does each SMY deck light use?
Each light uses 1 watt. Users report that the lights produce a stronger visual effect than they expected from their compact size and low individual power rating.
Are the lights difficult to connect?
The system uses plug-together connectors, which users found easy to assemble. The power supply is compact and includes mounting holes.
Is there really 1 meter of cable between each light?
The cable is advertised as 1 meter between lights. However, the effective fixture spacing may be less once the cable is routed through or around deck joists.
Can the cables be extended?
One installer extended the supplied cables using standard low-voltage lighting cable, butt splice connectors, and heat shrink. This made it possible to place fascia lights 34 inches apart when the original cable routing did not provide enough reach.
Where can SMY deck lights be installed?
The examples shown here include deck stairs and deck fascia. The best positions will depend on the deck design, available space behind the mounting surface, and the planned cable route.
What is the main installation issue to plan for?
Cable reach is the main consideration reported by users. Measure the routed distance between lights before drilling, especially when cables must pass through joists or follow an indirect path.
Final Buying Takeaway
SMY deck lights are a practical option for buyers who want compact 1-watt fixtures for deck stairs or fascia. Installation is straightforward when the layout is planned in advance: prepare a 7/8-inch hole saw, map the complete cable route, and confirm that the 1-meter cable sections will cover the intended spacing after passing through the deck structure.
The plug-together connectors and compact power supply help simplify installation, while the finished lights provide a bright nighttime effect. If wider spacing is required, account for possible cable extensions before beginning the project.
