I was going to replace both fixtures with LEDs, but now I see no point. This brand is an outstanding performer. ### ⭐⭐⭐⭐⭐ Price *by on Reviewed in the United States May 19, 2026* Great price for lights bulbs hard to find in a store ### ⭐⭐⭐⭐⭐ 8W warm white 29-530 *by on Reviewed in the United States January 18, 2026* Whilst i cannot rate the life span of a brand new tube, these lamps worked well straightaway, are brighter than those they replaced and seem reasonable in quality. For anyone needing specifics these are a direct replacement for hard-to-find warm white 29-530 (not 830) and will match surrounding traditional warm white tubes. Ordering from England, I have to say how reasonable shipping costs were for these lamps. ## Frequently Bought Together - F8T5 Fluorescent Light Bulbs - 12" Under Cabinet Bulb - Warm White 3000k 8 Watt Tube Bulb - Pack of 6 - (6 Pack) F13T5/WW - T5 Fluorescent 3000K Warm White - 21" Linear - 13 Watt T5 - Under The Counter Light Bulbs --- ## 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.jp/products/36073901-circle-f8t5-ww-t5-fluorescent-light-bulbs-12-inch-8w](https://www.desertcart.jp/products/36073901-circle-f8t5-ww-t5-fluorescent-light-bulbs-12-inch-8w) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-08-17*
