Once I realized that, the LED bulb worked fine!! ### ⭐⭐⭐⭐⭐ Long lasting *by A***R on 9 September 2025* Long lasting. ### ⭐⭐⭐⭐⭐ Worked great in old book light and in old flashlight. *by T***T on 28 September 2024* It fit just as well as the incandescent bulbs that only last for about 30 hours. There was a minor shadow cast from the internal circuit board, but for longer bulb life and battery life, I'll take it. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pt/products/396493648-ruiandsion-e10-led-bulb-4-5v-6v-screw-base-led](https://www.desertcart.pt/products/396493648-ruiandsion-e10-led-bulb-4-5v-6v-screw-base-led) --- *Product available on Desertcart Portugal* *Store origin: PT* *Last updated: 2026-07-11*
