Bright as daylight!,
Verified Purchase(What's this?)
This review is from: Feit Electric ESL40TN/D 40-Watt Compact Fluorescent High-Wattage Bulb, Daylight (Tools & Home Improvement)
Just got these today, so can't comment on longevity issues. They are instant-on without a flicker, but they take a couple of minutes to get up to full output. But once they are on, they are ON!!! I'm using them in my basement, and if you view the light from the top of the stairs you would swear it was natural sunlight. These are very bright and are perfect for my particular application - would probably be great for a garage or workshop too. Probably not suitable for use in a lamp (unless it's huge and you want sunlight-type light rather than soft white), definitely not suitable for use in an overhead light fixture. Overall I'm very pleased with the product, including its price. Also - mine arrived promptly (2 days with Prime shipping) and in perfect condition.
