"These bulbs are very bright a great replacement for the horrible amber bulbs and save you money in the long run with lower running costs. Just a bit on the pricey side but you get what you pay for and they are worth it."
"The bulbs give off exceptionally good light despite only being 8w. They are far brighter than the G10 50w bulbs that they have replaced. They are expensive and I am not totally convinced that they will last the two year warranty as one bulb has failed already after 3 months. This was replaced so I will now see how they go."
"These are great, white lights (Good in a kitchen for that clean effect). On the downside, like an earlier reviewer, I had one fail on me, which as they are touted as being long life and not cheap was something of a vexation! SF replaced with no quibbles and we are back with lots of sparkly light"
"I bought 6 for my kitchen. The 4000K cool white colour was not too blue and they really are as good as a 50w standard GU10. These transformed room!
But in less than a week they started to fail. Flashing on/off or running with a dim yellow glow.
The good news, after 5 replacements (done over several months) I have had no further failures (I dated the replacements). The last original lamp failed today, So I am hopeful this was a batch issue with the first lot of lamps.."
"This non-dimmable GU10 8W LED is very bright (cool white) and probably beats my original 50W lamp. Instantly bright when switched on. Rather pricey, but running cost only 1/6th, so hope to get payback this way! This lamp has a 2 year guarantee and surprisingly couldn't see life-time hours stated on box, but screwfix info states 30,000 hours. I will buy more."
"I purchased 8 of these for my kitchen and whilst the light color and power are fine I have had to return 6 as they keep failing. Some just go and some start to flicker, which is rather annoying.
SF have been fine with replacing them one at time, well apart from one person that thought it was a bad earth in the sockets when I showed them the video, so will keep taking them back but if any more go i might investigate swapping them out completely.
One person who also reviewed these mentioned it could have been a bad batch and interestingly i bought them around the same time 01/01/14, so hopefully it was just that."
"I bought 16 of these at great expense. They provide great light if not too bright. After little use they began to fail (5 in 3 weeks). SF has been brilliant and I have ended up changing them all for a different make."
"Great bright white light which is the best that I have seen BUT serious reliability problems. Original 4 failed in a month with only 4 hours a day switched on time. 2 of the next batch failed after 2 months and now another 1 has failed after a further month. SF have been very good replacing them but it is a hassle to have to keep taking them back. As yet have not found another brand with the same light output and beam width. I do not think that it is a defective batch as so many other reviewers (spread over quite a time scale and different locations) have had the same problem. It is just a bad product not fit for purpose."
"I bought a set of 4 of these bulbs. When I first switched them on they were excellently bright and I was very pleased. Then, 5 days later they began to fail one by one so I ended up swapping them for something else. Very disappointing - in my experience, these faults are either down to poor thermal management or getting brightness by overdriving lesser chips to save manufacturing costs. Hopefully it was just a bad batch but you wouldn't expect that from such an expensive product."
"A lot of money to pay for a light bulb that lasts for about 4 months. It now flashed on and off 2 times a second. The colour of light and brightness it gave off was good while it lasted but it must still be cheaper to use halogen bulbs that cost pence and pay the electricity than pay over £10 for these LED bulbs that just don't last."
