ᐅ Which E27 light bulb emits white light instead of yellow?

Hello,

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

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

So, a really nice white.

I have already tried:

It’s about E27 and GU10 bulbs.

Warm white 5.5 watts
Looks too yellow

Warm white 9.5 watts
Looks too yellow

Neutral white 9 watts, around 800 Kelvin
Looks too cold and too bright

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

Is there anything in between?

Thanks to everyone.

What you describe as the performance should be the luminous flux, meaning the amount of emitted light. However, it has nothing to do with the color temperature, although that is important to you!

It should be between 2600 and 3200° Kelvin (degrees Kelvin) if you want to achieve the light effect of traditional incandescent bulbs, but be careful:
Outside, natural light complicates things because its color temperature usually ranges between 7000 and 10000°K, and the eye quickly adapts to this, which causes artificial light sources to appear either yellowish or bluish very fast.
When standing outside and looking into a room, 2800°K appears very yellowish.
When inside a room with light sources at 2800°K and looking outside, the outside appears very blue. You can also see this effect in cameras when the white balance is off.

Wattage has nothing to do with the color temperature. Anything below 5000 Kelvin is yellowish, while anything above that is whiter.
The higher the Kelvin value, the whiter the light appears, but the blue component also increases.
Neutral white or warm white are simply other ways to describe the Kelvin value. Neutral is usually around 4000 K, warm white around 3000 K (or lower).

During the day, natural light starts very yellowish in the morning, becomes whiter around midday, and then turns yellow again toward the evening.
Therefore, white light looks very artificial for outdoor lighting.

Why do you want such cool light? It looks very artificial (and also quite cheap)...

Also, pay close attention to the wattage (or lumen output). 400 lm is not very much for indoor lighting, but it is quite strong for an outdoor light—especially if there is not much additional lighting nearby.

If I read the desire above correctly, I would aim for around 4000 kelvin.

It is also possible to have high-quality lights that adjust according to the outdoor color temperature. Of course, this costs significantly more than a standard E27 socket...

I faced the exact same problem some time ago.

I installed bulbs with a color temperature of 4000K everywhere, and that was the perfect choice! Not yellowish and not blue. Just a nice, pure white.
