What lux level does the IES recommend for kitchen task lighting?

✓ Accepted answer

The Illuminating Engineering Society (IES) recommends a minimum of 100 lux for general kitchen task lighting, though seniors with low vision may benefit from significantly higher levels up to 300 lux or more.

• Baseline Targets: While 100 lux is the standard minimum for safe cooking, individuals over 65 should aim for 300 lux at the counter level because the aging eye requires up to three times more light to perform the same task as a young adult.
• Color Temperature: Choose cooler white light between 3500K and 4100K for kitchen task areas. This temperature enhances contrast and alertness, making it easier to see the line of a knife or the color of food, compared to the warmer 2700K light used in living rooms.
• Layered Lighting: Do not rely on a single ceiling fixture. Instead, use under-cabinet lights to eliminate shadows cast by your hands. Motion-sensor strips are highly effective in closets and work zones, ensuring the light is on before you need it without the risk of tripping to find a switch.
• Measure and Adjust: A basic light meter costs less than 20 USD/GBP and is essential for verifying your setup. Place it on the cutting board; if the reading is below your target lux level, add a small LED task light. For UK readers, ensure your bulbs are rated for the correct voltage and wattage to match your existing fixture tracks.
• Glare Reduction: Bright light is useless if it is glaring. Use diffusers or frosted covers on under-cabinet LEDs. The light should illuminate the food, not shine directly into your eyes. This simple adjustment can reduce visual fatigue and improve safety during prolonged cooking sessions.
