## Customer Reviews

### ⭐⭐⭐⭐⭐ Excellent replacement
*by M***T on 5 July 2025*

Why did you choose this product over others?:Product met the required criteria. It was an excellent replacement and was easily fitted

### ⭐⭐⭐⭐⭐ Quality, brand name bulb
*by K***Y on 20 October 2024*

Once you have filtered out the right specification bulb you need (wattage, fit, size, light colour and brightness) how do you decide which one to purchase from the 'me - too' selection available? Are they all the same irrespective of price? Difficult to decide isn't it. For me, if there isn't much difference in the price I tend to go for the known brand option as I did in this case. I wasn't disappointed. The bulb was well packaged, has a quality look about it, fits into the holder well and works without flickering. Job done. Only time will tell if it lasts the 10,000 hours!

### ⭐⭐⭐⭐ Expensive but necessary
*by K***H on 14 September 2024*

Live in rented, silly light bulbs in the toilets, fit and works. Nice and bright. Did have to measure to check it would fit so make sure you measure the old one first. Expensive for one bulb but assume it's the going rate.
