Rated 4.8 out of 5 by 5 reviewers.
Rated 4.0 out of 5.0 by Brightness and color match existing lights in kitchen matches other bulbs in kitchen.................... December 9, 2014
Rated 5.0 out of 5.0 by For places that matter, this is the only bulb to use I tried four of these bulbs in my Mom's kitchen because of the "neutral" color temperature of 5000K and the CRI (Color Rendering Index) of 92. Changed out her old bulbs, turned on the light switch - the transformation was amazing; these bulbs made the kitchen look like it had just been remodeled. The color differences were striking; now the light is bright, accurate, and pleasant. Yes, you can purchase cool white (stark!) shop lamps with a CRI of 68 or 75 for a little less, but for kitchens, laundry rooms, closets, anywhere where you want an accurate "picture" of what you are seeing, these bulbs are the only way to go - once you've tried them you'll never go back!. I haven't tried the GE Sunshine bulbs (with a CRI of "only" 90); they are probably tolerable too. However, now, this is the only bulb I buy; if the store doesn't have this one I go somewhere else.

Rated 5.0 out of 5.0 by Nice color for kitchen lighting These bulbs give off a nice warm color light, perfect for the kitchen or bathroom. The color is not as harsh as the old bulbs that I have next to these. When the old bulbs go out, I will be replacing them with the Natural Light Supreme. August 20, 2014
Rated 5.0 out of 5.0 by Good light The light's "hue" is bright and natural. I replaced the lights in my laundry room, closet, and garage with these and am happy with them. I had originally purchased the "Daylight Deluxe" version and although they were maybe a slight bit brighter it was not a pleasant brightness, the slightly bluish hue was just not pleasant. I recommend these Natural Light Supremes. May 29, 2014
Rated 5.0 out of 5.0 by Will make you blink in the morning. These tubes are great for the kitchen. The color is not the ghastly bluish white that many fluorescent lights make, and they are so much brighter. I put a motion-activated LED night light in the kitchen to adjust my eyes in the morning before I hit the light switch. March 11, 2014
