Need a way to hold the ends during install. They are a little dimmer then the older bulbs I pulled out. ### ⭐⭐⭐ Nice *by M***R on Reviewed in the United States πŸ‡ΊπŸ‡Έ on May 10, 2021* Everything was good but one end popped off when I rotated the prongs into the fixture. I slipped the end back on and held it as I rotated the bulb prongs into the light fixture on the next attempt. It all still works. ### ⭐⭐⭐⭐⭐ LED Lamps easy to convert *by R***L on Reviewed in the United States πŸ‡ΊπŸ‡Έ on September 16, 2019* As instructed, I disconnected the old ballast and removed it from the fixture. Then rewired the 120 volt supply directly to the LED tube ends. The lamp installation was a little tricky since the connectors turn to allow the tube to be adjusted for optimum lighting. These lamps are very close to the same brightness and color of the fluorescent lamps I removed. --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.jp/products/82750086-4-pack-type-b-f21t5-led-tube-34-inch-cool](https://www.desertcart.jp/products/82750086-4-pack-type-b-f21t5-led-tube-34-inch-cool) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-08-11*
