Review: Sebson is high quality. - Be careful you get the right diameter bulbs (50mm, not 35mm), as the ad photos look identical. I first bought these two years ago. They put out more light than the halogen, and for one tenth the power. Sebson supplies a higher quality product compared to other bulbs I have seen - LEDs covered by glass, for example. I bought four more for my bathroom. Fast delivery, well packed, no problems. You may need a 12v LED transformer to avoid flickering. One transformer can drive three or four bulbs. The old transformer worked fine for a cluster of nine bulbs, but I needed an LED transformer to drive two bulbs without flickering.
Review: Fits and Works Perfectly - Really struggle these days to get these small bulbs locally, I only had 1 left that was working out of 2 and that was fitted quite some time ago. I'm so pleased to have found these on desertcart and they fit and work perfectly. Like the glow, it's bright but not over bearing, also replaced the old working bulb (pictured along side the new) so I have all new and the lighting matches, and they are just over 1.5m apart in their fitments and the lighting is still very gentle on the eyes.. Great value, should last a long time and save on electricity. Very happy customer.

### ⭐⭐⭐⭐⭐ Sebson is high quality.

### ⭐⭐⭐⭐⭐ Fits and Works Perfectly
*by J***. on 19 October 2020*

Really struggle these days to get these small bulbs locally, I only had 1 left that was working out of 2 and that was fitted quite some time ago. I'm so pleased to have found these on Amazon and they fit and work perfectly. Like the glow, it's bright but not over bearing, also replaced the old working bulb (pictured along side the new) so I have all new and the lighting matches, and they are just over 1.5m apart in their fitments and the lighting is still very gentle on the eyes.. Great value, should last a long time and save on electricity. Very happy customer.

### ⭐⭐⭐⭐ Good product, starting to be less durable
*by L***E on 24 September 2025*

I bought these twice, and in general they have been more reliable than most other brands. I have 10 lights in the room so I can get some idea of which ones work and which ones to avoid. The seller has changed these bulbs as the picture attached shows, and it seems the new ones are not as reliable: those fitted in 2023 still going strong, whilst one of the new ones has started to flicker after only 6 months ... I'm buying them again because the price is still good value for money and want to keep a consistent light quality. We'll see about lifespan.
