Pros: -Works

Cons: -Light fluctuates a lot
-If something is moving, you can feel the light flickering
-Low refresh rate

Pros: Very bright white LED bulbs. Looks just like a regular bulb! These are 40W but because of the bright white rating, they work like a 60W.

Cons: If you don't want bright white, go with 2700-3000L

Pros: - 5000K
- Low wattage
- LEDs
- Price
- Standard fixture

Cons: None so far.

Other Thoughts: I had the opportunity to set this up side-by-side with a 5000K CFL bulb, and by comparison, this one has a slight red-ish tint. I highly doubt that I would have noticed it if it was installed just by itself.
BTW, for people who think this is too "cold"/white, I use 5000K and 3700K in combination to get that Sunlight-yellow light that seems very natural. One or the other feels too warm or too cold.

Pros: Extremely cheap compared to other high dollar LED lights. Perfect for dimmer lighting in a children's lamp or nightlight. I use four for the living room and went from 240 watts used to 20 watts used. Great to conserve electricity.

Cons: I do not like the pale white light it gives off. I prefer lighting that has a yellow tint to it over these, but I'm sure I will get use to it over time.

Other Thoughts: Worth the money on sale at less than $3.70 a bulb.

Pros: I bought 4 of these on a special offer. Wish they'd allowed me to buy more. I replaced some 40w bulbs in my bathroom and they're much whiter and brighter than conventional bulbs, plus they don't waste power turning it into heat. You can grasp them after being on for half an hour and they're barely warm.

Cons: Unfortunately it's like any other new technology - too expensive! I'd replace all my fluorescent bulbs with LEDS if I could afford it. If the US government had any semblance of common sense they'd send a dozen to every household in this country and drastically cut power consumption across the board.

Other Thoughts: Like SSDs we'll have to wait a long time until the manufacturers have culled enough profit to lower the price.

Pros: Best for lamps. Nice white light. For 5- watts, 500 Lumens and 5000k no other Led bulbs can compare with the Rosewill. When on sale, the price can not be beaten. Does Not Get HOT. Only Luke, Luke Warm.

Cons: None what so ever!!!

Other Thoughts: Very happy with this bulb. Buy It, great buy.

Pros: 5000k is very bright. I replaced my 13w CFL with these 5w LED lights and I'm happy I did. I use them inside and outside the house. They give out more light than the CFL and less than 1/2 the watts. They also turn on instantly. These were 1/3 the price at the store where I bought different LED bulbs.

Cons: None.

Other Thoughts: I'm sad that I didn't buy a lot more at the combo price. After seeing them work, I went back to newegg and the combo was over.

Pros: What a disappointment.
Our new house has 53 can lights, 11 outdoor lights not counting path & garden lighting, 12 miniature halogens, etc. Can't imagine what the electric bills were for the previous owners. So, I've been buying lots of LED bulbs. I purchased 45 already from a certain membership chain (starts with Cos) and Lowes. They have all been great.

Unfortunately, I purchased these with inspecting the details closely enough.

These are the 5000k color temperature. The color is very bluish. The color is downright disgusting.

Not sure what I'll do with these bulbs. I might even return them even though the shipping will cost 1/3rd what I paid for them.

Cons: The 5000k temperature (color) is just awful.

Pros: I accidentally bought the wrong color temperature. These are very white/blue close to 6500K. Not very good for in house lights, luckily I managed to use them for some outside lights and it worked nicely. Nice value @3.50 a bulb - will last a very very very long time. Very bright, brighter than 60w incandescents in my house.

Cons: none - labelling on site could of been a little mor obvious to help me out when ordering. works like cool white or warm mean nothing.

Pros: Brighter than expected, steady, very efficient and runs cool on the globe. Does not fluctuate at all. Maybe some users had bad wiring or something wrong with their eye sight. After a couple of hours of being on, you can remove the bulb without waiting for it to cool. True INSTANT on. 100 lumens per watt in now the new norm.

Cons: Only the screw end base gets a little hot.

Other Thoughts: I'm looking forward to the newer LEDs with even more lumens and with the same style. I would like to see a 4000k half way between yellow and blue tint.. These are a super bargain when on sale.
