What is the correct color temperature for office use? Is soft white bright enough?

For office use you might want to get bulbs from 4500K (cool white) to 6500K (Daylight), soft white (2700K-3500K) is not suitable.

It is not the question of brightness. "Soft or Warm White" represents color temperatures typical for halogen (incandescent) lighting which a lot of people prefer over the "Cool White" light sources. If office activities are not critical for correct color rendering the 2700K - 3500K may be an acceptable color temperature. It is definitely not acceptable for doctor's office; art gallery or advertising agency office.

I think the soft white color would be ok for office use, but that probably depends what other bulbs you're mixing them with. The light produced by these bulbs isn't yellow like an incandescent, but it also isn't the stark white of a normal fluorescent bulb. If you're not mixing with any other bulbs, these produce a nice mid-warmth light.As far as brightness is concerned, I think these bulbs would be bright enough for almost any use. Once they warm up, which does take a few minutes, they produce a pretty significant amount of light over perhaps 10 feet in diameter of floor space.

Hmm, maybe if your outdoor area is really dark. In an office, it really needs to be fairly dark to be seen. I wouldn't think it would hold up if you had ambient light from outdoor street lamps or from your home.

These lamps are not quite as warm as incandescent bulbs, but they are not a harsh blue either. I am using them in two bedrooms and a long hallway and the light is a clear white and brighter than the incandescent candelabra bulbs that I was using. They seem to be the same color temperature whether at full brightness or at a reduced brightness.

The pkg. says that the color temp. is 2700K, which is what regular incandescent and CFLs are labeled as. However, I have some LED floods in my office that are 3000K which is a whiter light than 2700K and these Philips are more like the 3000K lights I have. I love them!

The color is bright white (really neither blue or yellow) and I'm not sure about temp. I don't feel any heat when the lights are on. We put them on a dimmer so we can adjust according to our needs. They are very bright which might be a concern for some.

color temperature is rated up to 3350k and classified as maximum performance extreme white light.

I used it in my office and it seems to be great during the day and my office is quite bright.

The color temperature is listed as 3000; in my house, this is a neutral white. It is not the "warm white" of an incandescent (2700), and it is not the "cold blue" of a 5000 daylight. Hope this helps!

AS noted below, the White in the RGB (Red, Green, Blue) isn't a true white. However, Amazon offers OLS kits in Bright White and Warm White. Amazon's number for the Bright White is B002CQ0GYA. Warm White is B004ZO3BSK. My eyes aren't very good, so I need A LOT of light. They are pretty bright and the bright white and warm white have similar features such as 8 dim / bright settings. Plus On / Off. The warm white is around 3000 to 3500K temp. Bright white is 6000K to 7000k. Hope that helps.

Color temp is around 5000K. As for lumens it's hard to tell. Maybe 100-150 lumens

I have seen no mention of the color temp of the LEDs. I would describe them as cool to cold. To my 65 year old eyes, when lighting pages on bright whitepaper there is the slightest blue tint, but when lighting scores that have yellowed with age the light seems wash out the yellow and sharpen the notes. It makes both situations easier to read.

The white temp is going to be a colder white in the high K's, maybe about 6000, but these multicolored floods (even the high wattage) are not really designed to produce adequate white light for a room or patio, etc. They are designed primarily for their color effect. Hope this maybe helpful.

Yes, you can choose bright or dim white in addition to the other colors. It is a pretty light.

It's color temp is 2700 to 6500. It works ok as desk or reading lamp. For general therapeutic effect, I prefer nature bright sun touch plus. I have both

I can't give you a scientific answer to your question but I can say this; i put them in a desk lamp using a 60W incandescent and in a ide lamp of a pole lamp using a 40W incandescent, and in both of those places, the Puilips bulb looks brighter to me. But I son't want to mislead you. I really have no idea about what color temperatures looks like. I did n''t even know colors had temperature. I'm jut giving you my "what it seems like by my eye view. I hope this helps.

It offers 3 different color temperature of soft white 2700K, warm white 3000K, and cool white 5000K. 2700K is about 800 lumens.

Good question; maybe would be clearer if you asked "color" temperature. I would expect about 5000K otherwise people would be complaining about blue garbage light.
