Great prices on your favourite Home brands, and free delivery on eligible orders.

Review: Can be used with or without the APP in your phone - I love this light. It’s quite small but creates an ambient feel if you select the static three colour mode. it has all other colours on it, but my preference is that one, it’s pretty as well as calming. I havnt put the app on my phone because it works perfectly ok without doing that as it has a switch on the light cord, that you can select the colours from once it’s plugged into a USB PORT. Hasn’t got a normal plug on it, so you would need a USB ADAPTER PLUG. I think if you bought the letters and wanted to make a word like LOVE or HOME etc and joined them together with the connector that is supplied with the HEART or the LETTERS, then maybe you would need the APP, I’m not sure, as I’ve only got the HEART. However, I am pleased with it, it’s quite unusual, and cute and a good price. Does not make any noise, good light quality, so far good functionality and not cheap looking. Easy to install.

*by G***U on 12 February 2026*

This is better than I thought. My sister loves it. Lights up really well and can be powered by your laptop, socket or power bank. It looks good and changes colour to music. Its a great gift and well worth the money.
