Overview

If you are finishing a basement, suite or renovation in Canada and do not have room for traditional cans, this 4" ultra slim recessed LED solves the problem. The Lotus LED-S9W series is less than 1/2" thick, installs under standard joists with no housing, and is certified for insulated ceilings and damp locations.

This 3000K warm white model (LED-S9W-3K-WH) delivers comfortable light for living spaces while keeping energy use low at only 9W, with Energy Star, cETLus and Type IC ratings for code-compliant projects.

Key Features

• Ultra slim & regressed design: Under 1/2" deep so it fits tight ceiling cavities and helps reduce glare compared to flat panels.
• Canless, Type IC rated: Designed to sit directly against insulation with no recessed can or separate housing required.
• Warm 3000K light: The LED-S9W-3K-WH variant provides a soft warm white colour ideal for family rooms, bedrooms and basements.
• Efficient 9W LED: Replaces roughly a 60W halogen while delivering about 600 lumens of usable light, saving power and heat.
• Integrated driver in connection box: The driver is built into the supplied connection box, so no separate junction box is needed for typical installs.
• Triac dimmable: Works with most compatible 120V CL / TRIAC wall dimmers for smooth dimming down to low light levels.
• Rated for Canadian conditions: cETLus listed, Energy Star certified and tested for ambient temperatures down to approximately -20°C, suitable for unheated spaces like garages and entries.
• 3 year warranty: Backed by Lotus LED Lights for residential and light commercial use.

Canadian Use Cases

• Basement suites and family rooms with low ceilings or lots of ducts and beams.
• Renovations where you do not want to open the whole ceiling for new cans.
• Bathrooms, laundry rooms and other damp locations (not directly in showers unless permitted by local code).
• Garage and cold entryway lighting down to around -20°C ambient.
• Multi-unit projects where contractors need a repeatable, inspector-friendly IC and airtight solution.

Common Questions

• Can I use this in an insulated ceiling?
  Yes. The LED-S9W series is Type IC rated and designed to be installed in insulated ceilings without a separate housing, following local electrical code.
• Is it safe for cold Canadian basements and garages?
  Yes. The fixture is rated for ambient temperatures down to roughly -20°C, so it is suitable for most unheated spaces in Canada when installed correctly.
• Do I need a special dimmer?
  Use a compatible 120V TRIAC / CL style dimmer. For best results, choose models listed by Lotus or test dimming performance before large installs.
• What if I’m not sure which colour temperature to pick?
  3000K is usually preferred for living areas and basements. If you want the option to tune colour on site, choose one of the 5CCT variants instead of a fixed 3000K or 4000K model.
