The Kohler Riff K-31757-SC03-2GL is a three-light vanity sconce with a contemporary geometric design that feels cleaner and more architectural than a traditional bath bar. Its 25-inch width gives it enough span for wider vanity mirrors, while the Brushed Moderne Brass finish adds warmth without softening the collection's modern character. This model is best suited to bathrooms where the lighting should read as part of the overall design language, not just as a utility fixture.
What bulb type does the Riff 3-light sconce use, and can LED bulbs be installed?
The source data for this listing does not confirm the exact bulb base, so `bulb_type` remains null. Buyers should confirm the required socket type and maximum wattage through Kohler documentation or the fixture label before purchasing bulbs. LED bulbs are generally suitable for vanity sconces when they match the socket and stay within the fixture's rating. Using matching lamps across all three positions is especially important on a wide fixture like this to keep the light output visually even.
Is the Riff 3-light hardwired to a wall box?
Yes, this is a hardwired wall-mounted vanity light. It should be installed on a suitable junction box and wired according to Kohler's instructions and local code requirements. Because the fixture has a broader 25-inch span, wall-box placement and centering matter more than they do with a smaller sconce. Proper support and alignment help the geometric design read cleanly once installed.
Does this model use frosted glass shades?
The product details you provided do not specify frosted glass shades for this Riff configuration. Buyers should therefore avoid assuming frosted glass is part of the package unless it is clearly listed in Kohler's current specifications. The Riff line is positioned around a contemporary geometric look, so the design emphasis is more on form and silhouette than on ornamental shade detailing. If diffused glass is a requirement, reviewing the official product images and cut sheet is the best next step.
How does the Brushed Moderne Brass finish fit with the Riff collection?
Brushed Moderne Brass adds warmth to the Riff collection without taking away from its modern, angular character. It coordinates best with Kohler fixtures and accessories in the same finish family, particularly when the bathroom uses other contemporary lines. Compared with chrome or black, this finish makes the geometry feel slightly softer and more upscale. The final appearance will shift somewhat depending on whether the room uses warm or cool lamp color temperatures.
Is the Riff 3-light vanity sconce UL listed?
Yes, this product entry is listed as UL listed. That means the fixture has been evaluated to recognized electrical safety standards, which is an important starting point for a permanent bathroom light. Buyers should still treat correct installation, grounding, and bulb selection as essential parts of the safety equation. UL listing supports confidence in the fixture, but it does not replace code-compliant installation practice.
