I was going to buy an LED bulb like this from local stores (including Blue and Orange Big Box stores) but they didn't have any. So I checked out Revain and found what I needed here. This 10W 4000K bulb puts out a bright white light but not as bright as the 6000K bulbs I use elsewhere in the house. As long as you're not looking directly at the bulb while it's on, there's no problem. Even if you catch a glimpse, it's not too bad for the eyes. I think it may take a while to get used to this as it replaced a 60w 2700k incandescent bulb which didn't produce enough light for my needs. parallel to the screw base, the light spreads out mainly from the "sides" of the bulb. So if you have that bulb in an overhead light that faces down like I did, you probably won't find it useful as a reading light when sitting under a light fixture. Yes, some light is projected downwards, but directly below the fixture the light level is noticeably lower. But where I use this lightbulb, it's not a big problem. At worst, this can cause slight inconveniences, but I haven't complained about this limitation so far. Overall, I love this LED lamp!
