JACKY LED 100% Original Super Bright Epistar Chips LED 2 Years Warranty Dimmable MR16 6W Lamps Day White Rotundity LED Mr16 12V Flood 60 Degrees Light Bulbs (Day White)

Bulbs in use for a month, now, and unlike previous purchases of other brands, none have failed, so this is encouraging.As other reviewers have noted, these bulbs are not "cool white", but a "day white" color, slightly warmer than cool white LED's. I have both colors now mixed on a long kitchen track light bar, and the color differences are noticeable, though not objectionable, in view of the reliability of the Jacky's to date.Seller needs to revise his advertising. The ad mentions many different colors plus cool white and warm white, yet there is no way on the site to choose exactly what you wish to buy. Until I actually got the bulbs, and tried them in the fixtures, it was a crap shoot as to what I had purchased.

Where to start?The good news first: The lamps survived the 8hour burn-in test. +1 StarWhat means 'JACKY LED 100% Original Super Bright Epistar Chips LED 2 Years Warranty Dimmable MR16 9W Lamps Red Green Blue Warm or Cool White Rotundity LED Mr16 12V Flood 60 Degrees Light Bulbs (Day White)' ?Well, the key word is 'Day white' because that means not warm white but also not cool white (6500K). +1StarSo what do you get?Definitely something that is not as bright as:[...]-Light-Bulb-E-ECS-16-50WE-WW-FL-TP/204632238It does not needs any measurements to find out that the Jacky LED is not as bright as the device from Home Depot. Because I was looking for a device that can deliver neutral white (6500K).Well, I've to admit that I am not patient enough to wait until they'll probably die after 50,000 hours...Whatsoever I found finally Soraa. That is exactly what I was looking for...

Unfortunately, I can't use it in the kitchen next to the other 3000K fixtures. Perhaps I didn't read the description closely enough - my bad. On the plus side, this bulb seems as bright as the 50w halogen bulbs I wanted to replace. The box in which it came apears to indicate that there may be a non-dimmable 3000k version. I'd love to get my hands on a dozen of them, but the seller doesn't appear to have them. I'd also love dozen dimmable 3000k bulbs, if they ever become available.

Confusing specs. It's day white not cool white. If your looking for cool white, don't buy these. I think they put cool white so this will show up on your search. I was searching for cool white, but didn't get it. Anyways, this has good lumens (500). Brighter than others. However, it does use 9w, so it might not be what you need if you have smaller transformer. I hope these last longer than my other led with same style.

I've now purchased 11 of these "JACKY LED" brand LED flood lights (9x GU10 and 2x of the 12v MR16 here) - I had to return the much pricier ($20 each!) locally sourced LEDs because of flickering. I'm glad I did, as the Jacky LEDs are brighter and don't flicker. The worst thing I can say about these is, if you don't like the crystal white (blue-tint) light, stick with the warm color versions. I personally love the cool blues, so these work great. They're not *quite* as bright as the outgoing halogens they replace, and the beam spread could be a bit wider - but overall, I'm exceptionally pleased with them, and so is my electricity bill.

I purchased several of these bulbs to replace 50 watt halogen bulbs in my office. The halogen bulbs are "rated" at about 400 lumens. These LED bulbs, although rated at 550 lumens, clearly provide less light output. The light is still adequate but not nearly as bright, a small price to pay for reducing energy consumption for this lighting by roughly 80%.

Description says "warm" or cool. Not sure what that means, I read the warm part. Replaced some MR16 50W halogens, and the light hue is almost blue. Looked horrible in my office. I will wait until the LED technonolgy improves with the color spectrum options, as these lamps cast an angry hue.

I have a problem bathroom outlet that burns out the MR16 bulb within a month of replacement. I grew so tired of replacing it that I just left it empty for a year. I decided to give this bulb a chance. It has lasted for 6 months so far. Great!
