When we wrote about dock and boathouse electrical for Muskoka last year, IP67 brass bollards and traditional path lights did most of the heavy lifting. A year and change later, the product landscape has moved. IP68 LED strip is finally serviceable enough to install on a permanent dock. Low-voltage bollard transformers have gotten smarter. And we are getting more requests for dark-sky-compliant dock lighting than for the lake-floods-the-bay setups people used to ask for. Here is what is actually on our trucks this summer for Port Carling, Baysville, and the Huntsville lakes.
What changed since last year
Three things, in rough order of impact:
- IP68 LED strip has stopped being a novelty. Three years ago we would not install it on a permanent dock — the silicone potting degraded under UV, the solder joints corroded, and a "10-year" strip would brown out at year three. The current generation (WAC InvisiLED Outdoor, Hera LED Tape EXT) is genuinely surviving the freeze-thaw cycle. We are seeing year-two installs come back clean, no visible degradation. Not yet ready to call it a 15-year fixture but absolutely now a 7-10 year one.
- Bollard product has improved at the mid price point. Vista, FX Luminaire, and Kichler all refreshed their landscape lines around 2026 with proper IP67 marine-rated cast brass and integral LED modules at lumen outputs that actually match what cottage owners want. The cheap aluminum bollard from the big-box store is still a 3-year throwaway. The $300-$400 brass bollard from a real landscape line is a 15-year fixture.
- The dark-sky conversation is real now. Bylaws around Lake of Bays and parts of Muskoka township have tightened on upward light spill. We are spec'ing more fixtures with full cutoff shielding than at any point in the last five years. Owners who used to ask for "the lake lit up" are now asking for downlight only, motion-activated, scheduled-off after midnight.
IP68 LED strip: where it works and where it does not
Where IP68 strip earns its place on a dock:
- Under the dock edge cap as a continuous downlight along the gunnel. Practical, low-glare, and the safety case (people stepping off the dock at night know where the edge is) is real.
- Inside the boathouse as cove lighting under the upper deck or along the slip walls. Indoor-rated strip will not survive the boathouse humidity; IP68 will.
- Stair nosings on dock stairs and any waterside steps. The strip mortared into a 2x2 channel under the nosing is invisible from above and the steps glow.
Where we will not install it:
- Anywhere subject to direct ice contact. Strip rated IP68 still gets crushed by ice pushing up under the dock in spring. We use bollards or in-deck fixtures with steel housings in those locations.
- On floating dock surfaces where freeze-thaw movement will work the silicone seal. Movement plus water plus a hundred freeze cycles wins eventually.
- As primary path lighting. The lumen output per foot is adequate for accent and edge lighting; it is not what you want for actual navigation of a dark path.
The transformer placement question
Low-voltage lighting needs a transformer. Where you put it is the question that decides whether the system lasts. The principles have not changed but they get violated every season:
- Inside the cottage or boathouse, dry location, well ventilated. Not in a damp crawl space, not in a sealed cabinet, not stuck to an exterior wall in direct sun.
- Sized at 80% loaded, not 100%. A 300W transformer running 240W of light load runs cool and lasts 15 years. A 300W transformer running 295W of load runs hot and dies at year five.
- Multi-tap on the secondary side so we can compensate for long-run voltage drop. A 50-metre run on 12V comes in at 9V at the fixture if you ignore voltage drop. The 13V or 15V tap solves it. Most landscape transformers worth installing have multi-tap secondaries; the cheap ones do not.
Underwater fixtures in 2027
Underwater dock lights are a polarizing topic. Done right they are gorgeous and safe. Done wrong they kill the fixture in a season and create a real safety issue. What we install:
- Pentair, Hayward, or Kichler in-water low-voltage LED with sealed cord-and-plug entry. IP68 rated, with the cable run in submersible pump cable inside conduit to a transformer above the water line.
- Equipotential bonding for every metal component the fixture touches — the bracket, any nearby ladder hardware, the boat lift if within 3 metres. The OESC and CSA marine codes are specific. We covered this in detail in last year's dock and boathouse electrical post and it has not changed.
- GFCI protection at the panel breaker, never at the dock. If you have an in-water fixture protected by a GFCI receptacle at the dock-side wall, the run between panel and GFCI is not protected. Move the GFCI to the panel.
- Disconnect within sight of the in-water circuit, lockable for winter shutdown and service. Non-negotiable.
Dark-sky compliance: the design shift
Five years ago a Muskoka dock lighting design might have included three or four uplights aimed at the boathouse facade, path lights with exposed bulbs, and a flood at the end of the dock pointed back toward the cottage. The waterfront-views crowd hated all of it; bylaws are catching up; the fixtures themselves now make compliance easier.
The dark-sky-friendly dock lighting design we install in 2027 looks like this:
- Full cutoff bollards at path edges. Light goes down, not sideways or up. Lumen output kept low (200-400 lumens per fixture) — enough to navigate, not enough to wash out the stars.
- Edge-cap LED strip as the dock perimeter marker. Downlight only, no glare across the water.
- Motion-activated brighter zones at the gangway and dock stairs. Dark by default, lit when someone is there, off after timeout.
- Astronomical timer on the lighting contactor — off by 11pm or midnight, on again at dusk. Lutron RA3, Leviton, or even a simple programmable timer at the panel does this cleanly.
- Warm colour temperature — 2200K to 2700K. The cool 4000K and 5000K fixtures the big-box stores sell are part of why people complain about dock lights ruining the cottage atmosphere.
The maintenance reality
Marine-grade brass and stainless fixtures still need annual attention. Every spring opening we are:
- Checking every fixture for water ingress at the lens seal.
- Cleaning algae and lake film off lenses with non-abrasive cloth.
- Testing every GFCI on the dock circuit at the panel.
- Inspecting cable runs above the high-water line for rodent damage.
- Confirming the transformer is reading nominal voltage on every secondary tap under load.
Twenty minutes of maintenance per spring buys a 15-year service life out of fixtures that would otherwise be 5-year throwaways.
When to call us
If you are designing dock or shoreline lighting for the 2027 or 2028 season, or replacing fixtures that did not survive the last few winters, we cover all of the lakes around Huntsville, Bracebridge, Gravenhurst, Port Carling, and Baysville. Request a site visit and we will walk the property, identify what is salvageable, and quote a design that will still be standing in 2037.
