Which E27 bulb is not yellow but white

Hello,

I have been searching for weeks for the right light source for my outdoor lighting.

I am looking for a white light that is neither yellow nor cold bluish.

So really nice white.

I have already tried:

It is about E27 and GU10

Warm white 5.5 watts
Looks too yellow

Warm white 9.5 watts
Looks too yellow

Neutral white 9 watts about 800 Kelvin
Looks too cold and too harsh

Neutral white 5.5 watts 460 Kelvin.
Does not dazzle but looks rather cold.

Is there anything in between at all?

Thanks to you

What you describe with the power should be the luminous flux, meaning the amount of emitted light. But it has nothing to do with the color temperature, which is important to you! It should be between 2600 and 3200° Kelvin (that is: degrees Kelvin) if you want to achieve the light effect of conventional incandescent bulbs, but beware: Outside, natural light spoils the plan because its color temperature is usually between 7000 and 10000°K and the eye adapts very quickly to it, which makes artificial light sources appear quickly yellowish or bluish. When standing outside and looking into a room, one believes 2800°K is totally yellowish. When standing in a room whose light sources have 2800°K and looking outside, one believes everything outside is totally blue. You can also see this effect in cameras where the white balance is incorrect.

The wattage has nothing to do with the color. Everything below 5000 Kelvin is yellow(ish), everything above is whiter. The higher the Kelvin rating, the whiter the light is (and appears), but the blue component then also increases. Neutral white or warm white are merely other descriptions for the Kelvin value. Neutral is rather 4000K, warm white rather 3000K (or below).

During the day, the light starts very yellow in the morning, then becomes whiter at noon, and turns yellow again in the evening. Thus, white light for outdoor lighting appears very artificial.

Why do you want such cool light? It appears very artificial (and very cheap as well...)

Also, take a close look at the wattage (or lumen output). 400lm for indoor lighting is not that much, for an outdoor light, it is quite a lot (especially if there isn't much additional light around).

If I read the wish above like that, I would lean towards around 4000 Kelvin.

There is also the possibility to have high-quality lights adjusted according to the external light temperature. Of course, it costs quite a bit more than an E27 socket...

I faced exactly the same problem some time ago. I installed lamps with 4000K everywhere and that was exactly the right color temperature! Not money and not blue. Simply nice white.
