Worked great. Easy fix. ### ⭐⭐⭐⭐⭐ Not your standard light bulb. *by L***T on March 7, 2026* It was a very odd light bulb, and I was afraid I would not be able to find it. The item arrived on time and waswell packed and was exactly what I needed. ### ⭐⭐⭐⭐ Good replacement for an old fluorescent bulb, but make sure the base is the same *by B***J on March 14, 2025* After 25 years the first of two bathroom ceiling lights finally went out. Carefully check the base, because the first one I bought had the wrong pin count, but this one was a perfect replacement. I was concerned at first, because only 2 of 4 bulbs lit up. However, checking the other bathroom, they all lit, and retrying in the 1st bathroom, they all did work. Probably a seating issue. Sometimes it seems to flicker a bit, but maybe I need to reseat it again. I was hoping to replace with an LED equivalent, but as far as I can see, they don't exist yet, or are much more expensive. --- ## 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.sk/products/270134745-kor-4-pack-13w-double-tube-cfl-light-bulbs-gx23](https://www.desertcart.sk/products/270134745-kor-4-pack-13w-double-tube-cfl-light-bulbs-gx23) --- *Product available on Desertcart Slovakia* *Store origin: SK* *Last updated: 2026-10-04*
