I love them. I love the just-right 5000K not-too-yellow and not-too-white spectrum.They're bright. I rewired my fixtures without the fluorescent ballasts, with them powered all on one end.Update: Dropped rating from 5 to 4 stars. 24 of the LEDs stopped working on one light. So much for the "life time of 45,000+ rated hours". --- ## 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/64542132-sdyk-4-pack-20w-4ft-plug-and-play-bypass-compatiblet8](https://www.desertcart.pt/products/64542132-sdyk-4-pack-20w-4ft-plug-and-play-bypass-compatiblet8) --- *Product available on Desertcart Portugal* *Store origin: PT* *Last updated: 2026-11-06*
