The Answer
The Short Answer
CRI is the most overlooked specification in lighting, yet it has the biggest impact on how your space actually looks and feels. Two bulbs can have identical brightness and colour temperature but dramatically different CRI scores — and the visual difference is immediately noticeable. High-CRI lighting makes everything look more vibrant, natural, and expensive.
The Full Explanation
CRI Ranges Explained
CRI 95–100: Excellent. Gallery-quality rendering, ideal for kitchens, bathrooms, and anywhere colour accuracy matters. CRI 90–95: Very good. Suitable for all living spaces. CRI 80–89: Acceptable for garages, utility rooms, and commercial spaces. CRI below 80: Avoid for any space where people spend time. Colours look washed out and unnatural.
Why CRI Matters More Than You Think
Low CRI lighting makes your home look cheaper than it is. Food loses its appeal under low-CRI light — restaurants have known this for decades, which is why high-end establishments always use CRI 95+ lighting. Your skin looks healthier under high-CRI light. If your bathroom mirror makes you look tired, the problem might be your bulb's CRI, not your sleep schedule.
How to Check CRI Before You Buy
CRI is printed on most quality LED packaging. Look for 'CRI 90+' or 'Ra90+' (Ra is the technical notation). Budget bulbs often omit CRI entirely — this usually means it's below 80. Premium brands like Philips, Soraa, and Yuji consistently produce CRI 95+ bulbs. Avoid bulbs that only list watts, lumens, and colour temperature without mentioning CRI.
