Havells Sylvania Sylvania 28w 2D Square 4-Pin Gr10q Cap Standard White (3500k) Compact Fluorescent Lamp, GR10, 28 W [Energy Class B]

The efficiency was great

Great

Well priced, well packaged and delivered on time. A warmer white and not as bright as my original, for which this was advertised as being a replacement by the same seller. No problem as it is lighting a small bathroom, but worth noting that it does not emit as bright a light as I expected...

I purchased this light tube in January 2017 and, despite the package claiming it would last for 11,000 hours or 11 years, it has lasted a mere seven months. The light bulb is in my kitchen pantry so only on for a few moments at a time. Does not live up to expectations.UPDATEI purchased two of these tubes back in January. As above, the first lasted seven months. The second has just gone - five months only and it's on for a maximum of 15 minutes a day ... if that. I strongly urge you not to buy. I am now going to try the Osram tube ... I'll update here with progress in due course.

Next day Sunday delivery through amazon prime. We'd purchased the wrong replacement bulb for our porch light but this was the correct bulb, fit perfectly and works well. Nice and bright so we no longer have a porch in darkness.

I originally purchased 1 bulb and have subsequently purchased 2 more. They are slightly brighter than the ones I used to buy from one of the major diy stores, which is great because with the diy store bulb I had to put on a second light in the room as the lumen wasn't bright enough. These Sylvania bulbs are also cheaper than the ones at the diy store, so definitely good value for money.

I buy it because it fits the bathroom light (we rent so I can't change it) and it works fine for 6 to 10 months then blows. Lives here 5 years and bought 10. Tried different brands and suppliers but makes no difference. This one is cheaper and lasts about the same as the more expensive ones. I'm not sure it makes it to 1000 hours, certainly nothing like the 10,000 claimed.

Great does the job

Non è vero che durano 10.000 ore, più o meno ogni anno le devo cambiare per cui la durata massima è di circa 1500 - 2000 ore!
