What to know before buying
- The listing's dimmer instructions specify LED trailing-edge dimmers and say traditional incandescent or halogen dimmers are unsuitable. Customer feedback also reports mixed dimming performance.
Listing details to confirm
Listing details are inconsistent or unconfirmed: the title and features identify an E14 G45 bulb, while the technical shape-size field says G16 1/2. It lists 230 Volts as well as 220 to 240 Volts and 50 Hertz, and includes Infrared and Touch controls for a bulb without explaining their relevance. Confirm the bulb shape and electrical details against the selected listing before purchase. The 30,000-hour lifespan is a listing claim, while customer feedback raises reliability and lifespan concerns.

Customer feedback describes a warm yellow glow, appealing appearance and positive impressions of quality and value. Dimming experiences are mixed, with some reports of smooth low dimming and others saying the bulbs do not dim. Reliability and lifespan are also concerns, including reports of bulbs failing within weeks or some in a pack not working. These reports matter for buyers relying on dimming or long service life, particularly because the listing claims dimming and a 30,000-hour average lifespan. The aggregate ratings are generally positive but do not resolve those specific concerns.
Positive themes
- Customers mention the warm yellow glow and appearance in fixtures.
- Customers report positive impressions of quality and value.
Negative themes
- Some customers report bulbs failing within weeks or only some bulbs in a pack working.
Mixed feedback
- Customer feedback differs on whether the bulbs dim smoothly or do not dim at all.
