I buy pretty much all our LED light-bulb replacements at Costco. I can get a three-pack for $9.99, or the huge-bulbed vanity lights in a three-pack for not more than $12.
The prices there are less than half. sometimes less than a third, of what I see at the local Home Depot, Lowe's or even BJ's. Thank you Costco. I don't know how they do it, given BJ's is also a warehouse store........
It's nice that these things come with ratings in lumens, but they are always dimmer than the specs on the incandescents they ostensibly replace. And I can't find 100-watt equivalents except in spotlights.
The LEDs I have seen don't come with ratings for color fidelity, like fluorescents do. Instead of the relatively flat curve of sunlight, or the similar curve from incandescents, they have a skinny blue spike and a much broader hump centered on yellow. They look white, and they are brighter, but I figure things must look different even though my color memory is not typically good enough to figure out how.
Comparing the colors of the different kinds of fluorescent bulbs is easier (daylight, cool, warm, grow: turned on, side-by-side, for me) than figuring out how it makes colors of objects different. Using the bright orange (mercury vapor?) lights in turnpike rest area parking lots, it is easy to see how things look different. A can of Coca Cola looks black (the red) and orange (the silver/white parts), or if I am misremembering it, at least it looks totally different than under white light. But I don't (for example) put on makeup, where more subtle differences in rendering could become clown-like.
Have you a Costco nearby?
