Quality, brand name bulb

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

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.

Service not great, bulb ok….so far

1st time I purchased for £9.60 and a 2 pin was sent incorrectly, I sent it back and when I clicked on the original listing for the 4-pin it was now £11.40! I know it’s a couple of £s but to send the wrong item and then list it 20% more within days seems wrong.It is also advertised as energy efficient, but looking at the rating bracket/label on the box…..it is not. I suppose the main thing is it works and I will update on how long.
