Has this ever happened to you? You purchase a bulb, install it in, turn it on, and immediately hate the colour of the light permanent lights on house. The problem is often color temperature, and that's very common with LEDs because the number of options is so broad.
The scale is measured in Kelvin, and at about 2,700K, the light is warm and golden, similar to an old incandescent bulb. Around 4000K, the light becomes neutral white. Increase the temperature to 5000K–6500K, and the light begins to feel brighter and cooler, similar to the way midday sunlight appears on a cloudless day.
Both the bedroom and family room generally work well with soft white at around 2700K to 3000K. The softer glow in this spectrum feels comfortable and relaxed, making it well suited for relaxing in the evening. Use a cooler temperature here and the room can start to feel more like an airport lounge.
Kitchens and bathrooms are often better with a 3500K-4000K range. When you're preparing food, you want to make sure you can see everything clearly while chopping ingredients. In the bathroom, you're applying makeup and want to see skin details clearly in the mirror. Neutral white light provides good visibility without appearing overly bright.
Home offices and garages can benefit from brighter and cooler lighting, typically 5000K and above. This is often described as daylight white. Higher color temperatures can help support concentration when completing tasks and may also make detailed work more comfortable.
Brightness is another consideration. Focus on lumens, not wattage. As a general estimate, around 800 lumens can replace the equivalent of an old 60-watt bulb in many table lamps. Reading areas typically need between 450–800 lumens, while a kitchen overhead light might require 1500+ lumens distributed across the entire room.
Another factor that many people overlook when switching to LED bulbs is the Colour Rendering Index, commonly called CRI. A CRI of 90+ provides a natural appearance for skin tones, food, and fabrics. LEDs with a low CRI can make red clothing appear muted or brownish.
