## Customer Reviews

### ⭐⭐⭐⭐⭐ The Shining 😁
*by T***M on 9 November 2025*

Excellent, really easy to fit and works perfectly. These bulbs last for a long time.

### ⭐⭐⭐⭐⭐ Good light bulbs
*by A***R on 7 January 2026*

It was good

### ⭐⭐⭐⭐⭐ Fantastic replacement! 😄
*by T***N on 22 January 2022*

I had trouble getting a replacement fluorescent T9 for our round fitting. Local shops had the dated ‘yellow’ style in abundance, but when the cool white version came out years ago I was much more inclined to buy that one than the ‘warm’ yellow, albeit I think it looked more like an old Street Light indoors! I think that colour IMO only conducive to certain environments, when put in contrast to cream/white walls? It feels like you’re standing in the middle of a massive omelette 😆 . The cool white colour definitely adds a crisper look to the stairway and a much brighter look overall. I’m pleased with the result and so long as this company makes them and I still need them then it’s definitely worth the money I paid out. The delivery was superb too arrived on the date specified on good time and very well packaged. I will definitely buy this product again in future. Thank you for allowing me to see my staircase again early in the morning! 😝
