ASD 40 in LED Under Cabinet Lighting - Dimmable 3 CCT, CRI 90

In this review the ASD 40 in LED under cabinet light is examined for anyone wanting dependable, restaurant-quality under-counter illumination without complicated wiring. The unit stands out for its flexible installation options and true-to-life color rendering: the built-in switch gives instant access to 2700K, 3000K and 4000K output while TRIAC compatibility enables smooth 10%-100% dimming when paired with a compatible dimmer. For homeowners and installers wanting crisp, flicker-free light and a choice between plug-in convenience or hardwired permanence, this light delivers the core features that matter most.

Key Features

• Seamless dimming: TRIAC dimmer compatibility provides flicker-free 10%-100% dimming for smooth ambiance control when used with compatible dimmers.
• Three color temperatures: A built-in switch selects 2700K, 3000K or 4000K instantly to match warm, neutral or bright task lighting needs without extra equipment.
• High color accuracy: CRI 90+ ensures food, surfaces and finishes appear true to life, useful for kitchens, displays and bathrooms where color fidelity matters.
• Dual installation options: The fixture can be hardwired for a permanent look or used with the plug-in option for quick, electrician-free installs.
• Linkable design: Included linking cords and connectors let multiple fixtures be connected seamlessly for continuous under-counter runs.
• Durable construction: Rugged aluminum housing and a rated 50,000-hour lifespan are backed by a five-year warranty for long-term reliability.

Who It's For

The ASD under-cabinet light is ideal for homeowners renovating kitchens, renters who want a non-permanent upgrade using the plug-in option, and DIY installers needing quick, bright under-counter illumination. Its high CRI and selectable color temps make it a good fit for home cooks, display shelving, bathroom vanities and other places where accurate color and adjustable brightness are important.

It is less suitable for buyers who require ultra-thin profile fixtures or integrated smart-home color controls; those seeking a low-profile puck-style light or networked smart lighting should look elsewhere. Also, users who cannot or do not want to handle basic mounting may prefer professional installation if hardwiring is chosen.
