Deck Lighting Collection for Railings and Outdoor Spaces
Light changes how a deck works at night. This collection features low voltage and solar options from LMT Mercer and Placid Point Lighting by Keylink. Run deck and landscape lights on one smart transformer and control them with Amazon or Google devices.
LMT Mercer low voltage and solar lighting
Reliable fixtures and simple wiring for a clean, proven setup.
LMT Mercer makes deck, fence, and landscape lighting, so one smart transformer can power the whole project. Use quick connect waterproof harnesses for fast installs and steady performance. Post cap options include halo caps that project light outward, downward caps that wash light onto the post and deck surface, and combo caps that do both. Low voltage caps provide bright, consistent light. Solar caps install where wiring is hard to reach.
We stock 2-1/2″ and 3-1/4″ caps to fit aluminum posts from Keylink, Deckorators, and Trex. LMT offers caps for many other post sizes, and we can order what you need direct from LMT. Pair the system with an LMT smart transformer to schedule, dim, and automate your deck and landscape lights from one hub.
Placid Point Lighting by Keylink
Purpose built to match Keylink aluminum railings.
Placid Point fixtures use durable die cast aluminum with a quality powder coat. Options include post cap lights, post and stair accent lights, and under rail lighting. Plug and play connectors let you daisy chain fixtures with tidy, secure connections.
The Placid Point power supply and control hub adds practical features. Set on and off times, use the photocell for dusk to dawn control, and adjust brightness as needed. A short walk away timer keeps lights on briefly as you exit. Lights and electronics include a 5 year limited warranty.
Color and finish options
A coordinated look across rail and lighting.
Placid Point Lighting is offered in colors that match Keylink’s wide range of matte, satin, and coastal finishes, so posts, rails, and lights share the same tone across the project. See Keylink’s options on the Placid Point page.

Which is better, low voltage or solar deck lighting
Both have a place. Low voltage is brighter and easier to control across large areas. Solar installs fast with no wiring and works well for accent spots.
What is the difference between halo, downward, and combo post caps
Halo glows around the cap edge. Downward shines onto the post and deck surface. Combo provides both effects in one light.
Can these lights stay out all year
Yes. Quality outdoor fixtures handle rain, snow, and temperature swings. Clean them occasionally to keep finishes looking their best.
Can I control deck and landscape lights with Amazon or Google devices
Yes. Use an LMT smart transformer, then set schedules, routines, and voice control for both deck and landscape lights.
Do LMT and Placid Point include a warranty
Yes. LMT Mercer and Placid Point lighting include a 5 year limited warranty on fixtures and electronics.
