10 Pack Sylvania 20671 CF13DDE835ECO 13-Watt 3500K 4-Pin Double Tube Compact Fluorescent Lamp

The Sylvania (10 Pack) 20671 CF13DD/E/835/ECO 13-Watt Double Tube Compact Fluorescent Lamp has met a mixed reception among customers. Many users appreciate the affordability and the fact that the bulbs fit well in their fixtures, indicating that they generally function as intended when new. Positive reviews highlight the satisfactory performance of the bulbs and the convenience of purchasing a pack of ten. However, there are notable concerns regarding the longevity and reliability of the bulbs. Some users reported that the bulbs tend to dim over time and don't last as long as older models they had in their homes, with complaints about not outlasting more than two years. Moreover, several customers experienced challenges related to their fixtures rather than the bulbs themselves, pointing to possibly faulty ballasts as a contributing factor to performance issues. The recommendation to replace fixtures instead of the bulbs underscores a perceived lack of reliability in this product. Some users have noted that finding replacement bulbs of this type is increasingly difficult as well, leading to frustrations among those who still rely on compact fluorescent technology. Overall, while the Sylvania Compact Fluorescent Lamps may offer an economical choice, customers are advised to weigh their options carefully, as the long-term effectiveness of these bulbs may not meet their expectations compared to newer lighting technologies, like LED. **
