FAQ - Frequently Asked Questions

1. Is Solo Color Plus suitable only for use in reading lamps or can it also be used as a ceiling lamp?

Solo Color Plus fits into any E27 light socket, wherever it might be …

2. Are lamps available for other types of socket?

At the moment, we offer only an E27 version. A suitable adapter would allow Solo Color Plus to be used in other light sockets, for example E14 or GU10.

3. Can I connect several Solo Color Plus lamps together?

No, we offer our Sengled Pulse product for multi-room sound and for connecting several speaker lamps.

4. Will Solo Color Plus work if it is shielded by a glass shade.

Generally, yes. It will work because the Bluetooth signal is only slightly weakened by the glass. Of course, sound would be heavily attenuated by an all-round lamp enclosure and this would naturally be noticeable in the sound quality.

5. How much light can I expect from Solo Color Plus?

Solo Color Plus emits up to 550 lumens. This is equivalent to the light output of a 45 watt incandescent light bulb.

6. Am I correct in thinking that Solo Color Plus works only with Apple devices?

No, that’s certainly not true! Solo Color Plus works with all devices that support Bluetooth and for which the Pulse app is available. This applies to products with iOS operating systems and to smart phones and tablets with Android operating systems.

7. Can the LED light part of the lamp burn out like a traditional incandescent light bulb? If so, are the LEDs replaceable?

No, LEDs cannot be replaced because they are permanently fixed into the lamps. However, the LED lamp in Sengled Pulse is designed for an operating life of 25,000 hours. In typical conditions of use of about three hours per day, this equates to more than 22 years.

8. Does Solo Color Plus also support WLAN (Wi-Fi) control?

No, the lamp connects to your mobile device only by Bluetooth.

9. If I switch off the light, can I continue to listen to music?

No problem, as long as you switch off the light using the app. Of course, if you use the light switch to do this, it will disconnect the power to the lamp. In that case, the sound also switches off.
