Pros: Replaced 12 CFL bulbs with these since they were a good deal on the daily sale. I put them all in and 12 out of 12 worked perfectly. No defects and they come on instantly. They done have a warm up time like CFLs do. They say 40 watt, but I think they are brighter than the 40 watt eq CFLs I had. I would say they are easily hitting the full 40 Watt brightness.

Cons: None - Not a single bad bulb :)

Other Thoughts: Normally I would expect 1 or 2 failures with 12 bulbs. I was very happy to find all 12 worked perfectly. That is a first for me.

Pros: Great price, very close color temperature to what I was expecting. Really like these lights.

Cons: none

Pros: Brighter than other LEDs previously purchased. Actually replaced a Phillips LED that claimed to be 40W equiv.; this bulb is nearly as bright as a 60W equiv. (should've measured the lumens) I have elsewhere in the room. My first purchase from Feit Electric, but took a chance at 3.50 per bulb; now my favorite brand so will purchase again.

Cons: claims cool white but yellow component makes a warmer light (which I prefer) than stark white

Other Thoughts: I bought 4 of these bulbs and wish I'd have purchased more with their December discount. Was shipped via UPS but handed off to USPS for local delivery.

Pros: Work great. Instant on. Warm light. decent light throw

Cons: Dont' tap them when they are on. My brother is more of a brute and has to touch everything he sees and did just that when they where on. It shorted out or something and wouldn't come back on until a reset of the light switch. Then it came back on without a problem.

Other Thoughts: Wouldn't be good as a utility light where you would lay it down or something and it would receive a jolt. Good for fixed lighting like on a wall or ceiling (out of reach of a giant four year old like my brother...)

Pros: First time buying LED replacement bulbs have used CFLs before, the pros are they are instant on instead of waiting for them to warm up to full brightness. Run cooler with less watts to get same output. Longevity will have to wait and see.

Cons: The con is that only the top half of the bulb lights up not the entire bulb. 2/3 is the plastic case and 1/3 puts out light.

Other Thoughts: These are good replacement for over head type ceiling lights like in ceiling fans or recessed light fixtures. I would not get them for table top or floor standing lamps since they do not shine light down if they are pointing up.
