Questions & Answers

What's the CRI of this bulb?

It's printed clearly on the box/packaging it comes in, but no photo of this Philips 5000K T12 bulb in it's packaging on this website.
Asked by: Eric
Yes, these used to be the best "looking" bulbs you could buy, with a CRI of 92 - and 5000K is not too "warm" - yellow - or "cool" - blue. However, for the last year or two when you get to the store you find Philips has changed their spec and this is now a 90 CRI bulb. Still way better for your kitchen or foyer or laundry room than a CRI 75 shop light, but 90 CRI bulbs are available at many more places than the 92 CRI bulbs were - and I haven't found any 92 CRI bulbs recently anywhere at any price.

Asked by: doggster
Hello and thank you for your question. While this is not the same as the Colortone light bulb, it matches other specifications and has a high CRI of 87.
