Garages are one of the harshest environments you can put a light fixture in. Moisture from rain and snowmelt, temperature swings from -30°C Canadian winters to summer heat, exhaust fumes, dust, and grease vapour all work together to destroy conventional lighting fast. If you’ve ever watched a standard shop light flicker out after a single winter, you already understand why the right fixture matters.
LED vapour proof lights for garages are purpose-built to survive exactly these conditions. Sealed, shatter-resistant, and dramatically more energy-efficient than fluorescent alternatives, they’re the go-to choice for commercial fleet garages, residential parkades, and everything in between. This guide covers what vapour proof LED fixtures are, how to choose the right one for your space, and how to calculate how many you need — so you can make a confident purchasing decision.
A vapour proof LED fixture is a fully sealed luminaire designed to prevent moisture, dust, and airborne contaminants from reaching the light source and driver. Unlike standard LED strip lights or open-frame shop lights, the housing, lens, and all entry points are gasketed and rated to keep the elements out.
The key spec to understand is the IP (Ingress Protection) rating, which uses two digits to describe how well a fixture resists solids and liquids:
• IP65 — dust-tight and protected against water jets. Suitable for most garages.
• IP66 — dust-tight and protected against powerful water jets. Recommended for wash-down environments.
• IP67 — dust-tight and protected against temporary submersion. Used in extreme applications.
For garages, IP65 is the minimum you should accept. If the space is regularly pressure-washed — such as a commercial fleet bay or car wash facility — step up to IP66.
You may also see IK ratings on some fixtures. These measure impact resistance on a scale of IK00 to IK10. In busy garages where forklifts, ladders, or equipment can make accidental contact with ceiling-mounted fixtures, an IK08 or higher rating adds meaningful protection.
Not all garages look alike, but they share one thing: they punish the wrong lighting choice. Here’s what different garage environments throw at their fixtures.
Canadian winters are hard on lighting. Snow and ice tracked in by vehicles create persistent damp conditions. Salt corrosion from road treatment attacks any unsealed metal components. Temperature swings between a heated lobby and an unheated parkade cause condensation to form on fixtures regularly. A sealed vapour proof LED handles all of this without issue; an unsealed fixture develops rust, corroded sockets, and premature driver failure within a few seasons.
In a working garage — dealership service bays, municipal fleet maintenance, or trucking depots — grease vapour rises from vehicles constantly. Chemical cleaners are used on floors and equipment. Pressure washing is routine. Standard LED fixtures simply aren’t built for this environment. The gaskets on a vapour proof fixture keep all of this out of the housing, protecting the driver and LEDs for the full rated lifespan.
Underground parkades deal with heavy condensation from temperature differentials between the structure and outside air. In attached structures, proximity to heated building space creates its own moisture dynamics. Beyond the physical environment, parking structure lighting often falls under fire and building code requirements in Ontario — using appropriately rated fixtures keeps you compliant.
Not all vapour proof LED fixtures are created equal. Here is what to evaluate before you buy.
For most garage applications, you’ll be looking at fixtures in the 30W–80W range. A practical rule of thumb is 50 lumens per square foot for general-purpose garage lighting. Dedicated work bays where colour accuracy and detail visibility matter — such as auto body repair — benefit from pushing toward 70–80 lumens per square foot.
Look for DLC (DesignLights Consortium) certified fixtures. DLC certification is a baseline quality standard and is also required for most Canadian energy rebate programmes, including Ontario’s Save on Energy incentives.
IP65 suits the majority of garage environments. If your space sees regular pressure washing, specify IP66. If you are ever unsure, IP66 adds negligible cost and meaningfully extends fixture life.
Colour temperature is measured in Kelvin (K) and affects how a space feels and how well you can see fine detail. For garage work, 5000K–6500K (cool, daylight-range white light) is standard — it maximises contrast and makes it easier to spot issues under a hood or on a workbench. If the garage doubles as a home workshop or hobby space where ambiance matters, 4000K offers a cleaner, neutral-white look without feeling clinical.
Vapour proof fixtures typically mount in one of three ways: surface-mounted directly to the ceiling, suspended by chains or cables (useful for higher ceilings or where cable management is needed), or wall-mounted in some models. For ceilings under 14 feet, surface or chain mounting works well. Above 14–16 feet, consider whether a standard vapour proof is adequate or whether you need a high-bay vapour proof variant with higher lumen output.
Many vapour proof LED fixtures support daisy-chaining, where multiple units are wired together in a series from a single power connection. This simplifies installation significantly in long garage runs — a row of 6–8 fixtures in a fleet bay, for example, can be linked end-to-end rather than requiring individual home-runs back to the panel.
If your garage currently has fluorescent vapour proof fixtures, you’re already ahead of someone using open shop lights — but there’s still a compelling case to make the switch to LED.
• Energy use: LED vapour proof fixtures typically consume 50–60% less power than equivalent fluorescent vapour proofs. A fluorescent 2x4 vapour proof running at 96W can often be replaced by a 40–45W LED delivering equal or greater lumen output.
• Lifespan: Quality LED fixtures are rated at 100,000+ hours. Fluorescent tubes typically run 15,000–20,000 hours before needing replacement — plus the ongoing cost and labour of re-lamping.
• Cold weather performance: Fluorescent lamps degrade noticeably below -10°C, flickering, slow to start, and outputting significantly less light. LED is unaffected by cold — it turns on instantly and outputs full brightness at -40°C.
• Rebate eligibility: DLC-certified LED upgrades qualify for Canadian energy efficiency rebates that fluorescent replacements do not. This can offset a significant portion of upfront costs.
For facilities with large numbers of fixtures — a parking structure with 40 vapour proofs, for example — the energy and maintenance savings typically produce a payback period of 2–4 years, with 10+ additional years of near-zero maintenance after that. AALED’s instant discounts programme can help further reduce the upfront cost. See aaled.ca/instant-discounts for current rebate-eligible products.
A simple lumen calculation gives you a reliable starting point. Here’s the method:
• Measure your garage’s square footage (length x width).
• Multiply by your target foot-candles (50 fc for general use; 70–80 fc for detailed work).
• Divide by the lumen output of your chosen fixture to get the number of units needed.
Example: A standard 2-bay residential garage is roughly 400–500 sq ft. At 50 foot-candles, you need approximately 20,000–25,000 lumens total. A 40W LED vapour proof producing 5,000 lumens covers that with 4–5 fixtures — or 2–3 fixtures if you opt for a higher-output 60W model.
For commercial layouts with irregular shapes, obstructions, or specific code requirements, a lighting plan is worth the time. Contact AALED’s lighting consultants at aaled.ca for a no-cost layout recommendation tailored to your space.
A quality fixture installed poorly will not perform as rated. Keep these points in mind:
• Follow Ontario ESA electrical code: All hardwired fixture installations in Ontario must comply with the Ontario Electrical Safety Code. For commercial installations, use a licensed electrician.
• Seal your junction box: The fixture’s IP rating covers the housing — not the conduit entry or junction box. Use appropriately rated conduit fittings and seal conduit entries to maintain the environmental rating at the connection point.
• Check conduit sealing in damp locations: In locations classified as “damp” or “wet” under electrical code, conduit sealing at the fixture entry is required. Do not skip this step in underground or exposed parkade environments.
• Verify dimming compatibility: If you intend to use occupancy sensors or 0–10V dimming controls, confirm that your chosen fixture supports it before purchasing. Not all vapour proof models are dimmable
.• Respect ceiling height: For ceilings under 14 ft, standard vapour proofs work well. Above that threshold, look at high-bay vapour proof models with higher lumen packages to maintain adequate foot-candle levels at floor height.

“Waterproof” is a general term with no standardised definition in lighting. “Vapour proof” is a specific fixture category with a fully sealed housing designed to keep out moisture, dust, and airborne vapours. All vapour proof fixtures carry an IP rating (typically IP65 or higher) that gives you a measurable, tested guarantee of protection. When buying for a garage, always look for the IP rating rather than relying on “waterproof” labelling alone.
Yes — LED is one of the best technologies for cold-climate garage lighting. Unlike fluorescent, which slows to start and loses output below -10°C, LED turns on instantly and maintains full brightness at temperatures as low as -40°C. For unheated Canadian garages, this is one of the strongest practical arguments for making the switch.
IP65 is the minimum recommended rating for garage environments — it covers dust and water jets from any direction. If your garage is regularly pressure-washed or exposed to heavy water spray (such as a commercial fleet bay or car wash facility), specify IP66. For most residential garages and standard commercial parkades, IP65 is sufficient.
Yes. DLC-certified LED vapour proof fixtures qualify for rebates through Ontario’s Save on Energy programme and other Canadian energy efficiency incentives. The rebate amount varies based on the fixture wattage and the number of units being installed. AALED can help you identify eligible products and navigate the application process — visit aaled.ca/instant-discounts for current offers.
Quality LED vapour proof fixtures are rated for 170,000 hours or more. Running a fixture 12 hours per day, that translates to over 11 years before reaching the rated end-of-life lumen maintenance point (typically L70, meaning 70% of original output). In practice, most fixtures continue functioning well beyond that point — the contrast with fluorescent tubes, which need re-lamping every 2–3 years, is significant for both maintenance cost and downtime.
