Value for money

Easy to install

Brilliant, I’ve finally found a bulb that actually works! These are getting harder to find locally. Unlike the cheap brands, that having been cut out, within minutes of installing. I honestly thought my fitting was faulty. But then I purchased this bulb and finally can see whilst I take a Bath.

I've ordered these bulbs three times and on each occasion they have lasted at least two years!! I'm not sure why some buyers have had a problem with these - maybe they were dropped before delivery? Anyway, would recommend them. Dead easy to install and a nice bright light.

You can only return this in the first month, mine failed after 6 months use, which I estimate to be 20 hours use in my case, maximum. Really inconvenient having to now go shopping for another bulb, spending more money. Advertised as 8000 hours. It would have been less inconvenient flushing £10 down the toilet and buying a more reputable brand back in April, I'd have saved myself time and wouldn't be having to 'take aim' in the bathroom in an evening like I'm having to now!! Save your money, buy Osram...

I recently purchased the TBE LIGHTING 28w 2D 4-PIN CFL Energy Saving Lamp, and I’m very impressed with its performance. The soft white 3500K light is perfect—not too harsh and not too dim, making it ideal for both work and relaxation. The installation was a breeze thanks to the GR10q base, which fit perfectly with my light fixture. What I love most is the brightness—it lights up the room evenly without flickering. As someone who values energy efficiency, it's a relief to find a bulb that delivers great brightness while being energy-saving. It's been working flawlessly, and the build quality feels sturdy, so I’m confident it will last a long time. Highly recommend this bulb to anyone looking for a reliable, energy-efficient lighting solution!

It lasted 9 months, then I had to get another. So a long way from 8000 hrs, in fact a lot less than 800. Otherwise It worked fine for that time & I have no other complaint.

ampoule néon

Passade tyvärr inte i den gamla armaturen. Rören sitter inte exakt på samma ställe som den äldre varianten.

Funziona, ottimo.

La lampada è arrivata rotta.Avviato reso.

Wrong size, more than double the normal size. Unusable and seller refused return. Don't buy
