4 ft. T12 40-Watt Natural Supreme Linear Fluorescent Light Bulb (2-Pack) is rated 4.7 out of 5 by 7.
Rated 5 out of 5 by from Bright light in kitchen In small kitchen I changed out 3000K soft white with these 5000K natural light. 4 bulbs. They don't look as good, but they are way more effective. Major change for $20. Since these are bright I will now tone down my dining room light. Yes, try them.

Rated 5 out of 5 by from 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.

Rated 5 out of 5 by from 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 out of 5 by from 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.

Rated 5 out of 5 by from 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.
