Question: what is its temperature? 4000K or 5000K? I am amazed at how many vendors leave that critical piece of information out.
Document: I've been replacing all my lighting with LED bulbs. Over the past year, so many of the different LED bulbs I've purchased have been a disappointment, but NOT these LED units for my recessed 5" shower ceiling cans. Installation was easy and well explained in the enclosed instructions. The only drawback (one star off) was the flimsy ring seal that was worthless, so I bought new seal rings from Ace Hardware that gave me a great seal between the light and the ceiling.
I have had a love/hate relationship with LED lighting for many years.I love the idea of efficiency and long life, but have had terrible experiences with LED bulb light output and color consistency. Most LED solutions were too dim or a strange color of what was marketed as 'warm white'. Other times the LED lights have been harsh and glaring.I purchased 4 of these from a big box home improvement store (for signifcantly less than sold here BTW - whats going on Amazon?)
Although I did not buy them at Amazon, I saved $20 a piece at Home Depot. These things are amazing. For years I just kept replacing the old "flood" lights that just sucked up electricity. I was looking around for some kind of light I could replace these with. Theres really not that much. When these canisters are installed theres no sheet rock,so to get them out it's almost impossible without tearing out the ceiling.Then I saw these LED lights. Simple and extremely energy efficient.
I would recommend shopping around--got mine from the local Home Depot for less than the Amazon price, but we couldn't find them cheaper anywhere online.
4 lights took about 20 minutes tops.The heat coming off the old lights was intense. These things... Cool as can be. I am sold. I will put the other 6 in the living room cannisters this week. The light given off is not yellowed at all. Very clean, very easy on the eyes.
I just bought 10 of these last night from the local big orange store. I bought the Cree line initially, but they did not fit the canisters. Returned them and actually got a very knowledgeable associate to help me out on the second attempt. I installed 4 of them last night and am impressed so far.
My handyman bought these from the big-box store for new recessed lights we wanted to put in out master bedroom. I love these lights ... the color is pleasing. It is dimmable and best of all it uses very low energy and last 22 years!! I plan on slowly replacing my incandescent can lights with these. Would highly recommend.
I just bought 12 of these lights, to replace halogen incandescent bulbs. Installation is very easy. The light color is just right, although slightly less intense than the halogen bulbs. I am giving them only three starts for three reasons:1. The gasket that comes with it is very flimsy, and does nearly nothing to stop the attic dust from entering the house envelope.2.
The light is actually brighter than my incandescent and I like the color better--warm, but much closer to natural light--not yellow. They don't need to "warm up" like fluorescent, and work beautifully on my dimmer. The fixture looks high-end; white baffle and trim and no GE logo on the exposed bulb (there IS no exposed bulb:-) Although initial cost is intimidating (did I mention we have 28 cans?)
We purchased two of these lights for our bedroom just to try them out prior to a remodel. We currently have 28 cans in the house; all burn 65 watt incandescent and we seem to be replacing them every 6 months to a year-- costly and irritating. I had low expectations for the LED, fearing glaring blue tinged Christmas lights, but figured if they really could last 22+ years and not heat the house in the summer they were worth a go. I have NO complaints with these!
Answer: no
