Bought the KAYVA GU10 for my living room. The light is quite nice, not too harsh and colour looks very natural. Previous bulb was quite yellowish, this one much better. Happy with the purchase.

Frequently asked questions
How does the two-colour switching work?
Switch on for 2700K warm white. Flip the wall switch off and on again within a couple of seconds and it changes to 4000K neutral. No app, no hub, no WiFi — the colour is controlled by the light switch you already have.
Is it dimmable?
No. The Switch is non-dimmable by design — the switching mechanism and dimming do not coexist cleanly. If you want dimming, choose the GU10 Dim instead; if you want two colour temperatures without an app, the Switch is the one.
Why choose this over a smart bulb?
It gives you two useful colour temperatures — warm for evenings, neutral for tasks — with nothing to set up, no app to be discontinued, and nothing to fail when the WiFi is down. It works the day you install it and in ten years' time.
What wattage and fitting is it?
7W, standard GU10 base, mains voltage. A direct replacement for any GU10 halogen or LED, in downlights or track heads. No transformer required.
Is the colour quality the same in both temperatures?
Yes. Both 2700K and 4000K are Ra95+ with R9>80 — the same colour accuracy, tested per batch. Only the warmth of the white changes when you switch.
What customers say
Got the 2700K GU10 for bedroom. Was worried it would be too yellow but actually just nice, very cosy at night. Dimming also works quite smoothly with my setup.
My ID recommended KAYVA because of the high CRI. At first I thought lighting all same, but after installation can really see the difference. Wood colour and furniture look more natural.
Very nice solid colour of 2700K compared to my previous strip, which is also 2700K. KAYVA strip gives me a more relaxing and warm feel. The price point is slightly on the higher end but worth it overall.
photo review, no comment
Really glad to stumble upon these lights when looking for ceiling lights for my kitchen. Did some testing but have not fix yet but impression is good. Just amazed that seller published the spectrometer of this E27 bulb! even the giant brands don't do that. It is important to me as I have been following the research of a UCL scientist on health concerns of white LED. The 2700K bulb is great with minor little output on those wavelengths of concern. Also, it is dimmable and not too expensive compared to other bulbs and hence deserved this rating.

COLOUR ACCURACY
Ra95+ rendering, true to life.
Most GU10s sit around Ra80. KAYVA runs at Ra95+ R9>80, which means skin tones, fabrics, and finishes look the way they actually do — not washed out or shifted cool.

DEEP RED RENDERING
R9 above 80. The difference you see.
Ra95+ alone doesn't tell the full story. R9 measures deep red accuracy — skin tones, warm wood, rich fabric. KAYVA GU10 Switch scores R9=86. Most Ra90 bulbs score below 30.
