4 out of 10 tubes were bad.
I installed these today immediately after receiving them and 4 out 10 tubes are bad. I switched them around to make sure and the issues followed the tubes. 2 are very dim and have darkened ends. One refuses to light at all. Another again refuses to light except very dimly one time. Not happy. This was a lot of work to get up on the ladder and replace these.

    5.0 out of 5 stars Color Rendering Index of 90, but they lack a moisture-repellent coating
    Reviewed in the United States on April 29, 2018
    Color: Daylight DeluxeSize: 10 Count (Pack of 1)Pattern Name: 40 WConfiguration: T12Verified Purchase
    Dirt used to be the usual reason a fluorescent lamp wouldn't light when it was humid. In F40 needs about 200 volts end-to-end to strike the arc. Damp dirt could cause enough electrical leakage to draw the voltage below 200. I could usually fix a troublesome tube by washing it in the shower.

    My house uses nine F40T12 tubes. Most had been in use more than 20 years. A tube that's failing usually gives plenty of notice by blackening at one or both ends. It may continue to work for years, but it's fading away. Some of mine had blackening, and one day, one would no longer start. I ordered from Amazon because, not having replaced a tube in years, I forgot I had a spare. I'm glad I forgot!

    The manufacturer used a simple box with a separator at each end to keep the bulbs from hitting each other. Amazon wrapped the box in the kind of bubble wrap that's a little over 1mm thick. and put that box loose in a larger box. It looked disastrous, but the tubes seemed OK. I didn't know fluorescent tubes were so tough!

    The old CW (cool white) produced a lot of lumens. It was efficient for reading, but the Color Rendering Index was only 62. Mostly green and yellow, it was gloomy at low levels. Warm white colors were too orange for me. Daylight colors were too blue. I preferred CWX. It was less efficient than CW, but at 78, it had a better CRI than other colors. I found it more cheerful, and blues and reds showed better.

    When Amazon's description called these bulbs Daylight Deluxe, I remembered the old Daylight, which also had a color temperature of 6500K. The CRI was 58. I thought I wouldn't like the color of these new tubes, but at least they'd light when I flipped the switch. I was so pleasantly surprised that I found the Philips data sheet. The CRI is 90!

    I replaced the failed tube. Then I replaced a CWX with a darkened end. Being new, the Philips was brighter. I also saw a better color. It was such an improvement that I got a stepladder and replaced all tubes with blackening. I may end up replacing tubes without blackening because I prefer the color.

    I had occasional failures to start in the bathroom and the kitchen, two rooms where the humidity is sometimes high. The bulbs looked clean, and washing was not a lasting solution. That left one possibility.

    Glass is hydrophilic. In humid conditions, enough water molecules can stick to make the surface damp. Fluorescent tubes used to have a coating to repel moisture. It seems these tubes have not been treated. Rain-x is a water-repellent coating for windshields. I have some Rain-x somewhere, but the first thing I spotted was an old can of silicone spray intended to make clothing and leather water repellent.

    I wiped some onto the two bulbs exposed to high humidity. After a year, during a rainy spell when indoor humidity reached 78%, I had trouble again. Dust had stuck to the coating. By now I'd found my Rain-x. I washed off the old coating and applied it. I haven't had any trouble since.

    Great product: very bright, super white light, Unfortunately, is packaged to be opened like a suitcase, with the bulbs lying flat in 2 rows of 5... making it precarious to store vertically once opened if you only need a few at a time.
