At any level under 100% there is an audible buzzing sound- it gets louder the dimmer you get, but even at say 90% brightness it's still very noticeable to me, and that was just a single bulb- I had planned on using three of them in a fan in my living room, but I could never use them with the sound they make at the lower brightness levels- I mean, it goes hand in hand more or less that where you want dim lighting (bedrooms, living rooms, dens, etc...) you also need quiet and that would just be impossible with these.However, I am in no way returning them- they will work excellent in fixtures that do not have dimmers- closets, some hallways, places where they will only be "on" or "off" - much brighter than my current bulbs and will use a fraction of the power.One final warning, though it didn't affect my rating one way or the other- they are physically larger than a standard 100 watt typical light bulb... I'd say off hand they are probably close to double the size, you need a deep and wide fixture to fit these in, if your regular bulb barely fits these will not. I tried it in a high-hat light I had in my basement that typical bulbs always fit with 1.5" or so to spare, these bulbs stick out below the opening another inch or more. ### ⭐⭐⭐⭐ Very reasonable price. *by K***O on Reviewed in the United States on May 18, 2013* I bought this because it is inexpensive. It does not last as long as it said on the box. I have never used other brands so I do not know how other brand bulbs last. ### ⭐ One Star *by N***B on Reviewed in the United States on April 9, 2016* Lasted 3 months! --- ## 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.co.uk/products/20895154-dimmable-compact-fluorescent-light-cfl-bulbs-23w-100w-ulamerica-model](https://www.desertcart.co.uk/products/20895154-dimmable-compact-fluorescent-light-cfl-bulbs-23w-100w-ulamerica-model) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-06-12*
