Great color and brightness is adjustable if you are using a dimmer switch. Lumens we're on printed on label on the box and not marked on bulbs, but the brightness seems about right.I got these to replace some LED lights I had put in to replace some other lights which were failing. There were some 85W lights (incandescent) which had been used for a few years, and I didn't know the housemate already had replacement bulbs (because I expected he would have replaced the burned out bulbs if we had some... my bad.) so I just took some random 5k LED bulbs from my stockpile and replaced them. They appeared brighter (the stuff he had was warm white) but were only 60W replacement bulbs. So the color temperature can only take it so far... Basically the living room looked like a dungeon before, then looked like a somewhat more welcoming dungeon. One of my bulbs started burning out, so I figured I'd get some bulbs of the correct type and wattage replacement conversion factor (not sure on the phrasing there. I'm not a lighting guy, so maybe there's a term I'm missing). Let me tell you - HUGE DIFFERENCE! These are not daylight spectrum, which I'd personally prefer... But it's crazy how much brighter the room is. It's the brightest I've ever seen it in there. These bulbs just put out so much light it's amazing. I hope they last as long as they say they do, because they're my go-to for light replacements of this style going forward if so.Pros:- Bright (lumens, not color)- Relatively low wattage- Not terribly expensiveCons:- None so far.Other thoughts:- I wish I got the daylight version. Might have been too much for my house mates though, as they tend to not go outside so much and like things a little darker.- I don't have a dimmer, so I have no idea how they fare with a dimmer in the mix.
