You can also visit their website at www.ott-lite.com. A customer service representative can assist you in figuring out the best replacement bulb. Once you have that information you can then shop online for the best deal. Hope this helps. **Q: How can I purchase one--it's only markings are 9209 and True color OLT-18W which does not match anything I can find on line? thank you?** A: The bulb at the following link is the only 18 watt twin tube bulb that Ott makes:http://www.amazon.com/OTT-LITE-Watt-Pin-Replacement-Bulb/dp/B000EMCRP0/ref=cm_cd_al_qh_dp_i **Q: Is this a TrueColor bulb?** A: The description calls it a "daylight" bulb. In terms of color temperature, that would mean that there is no shift in the color spectrum as you would have if your were reading under a florescent bulb. If you are planning to use your Ott-Lite as photo lighting, I feel that you would be happy with your photos. **Q: I have a floor model ott lamp, model fl-18 (on the base of the lamp) and i need an 18w four prong light bulb replacement. what is the bulb order #?** A: I did not have a model number.....I just bought an 18 four prong.....and it fits just fine..... ## Customer Reviews ### ⭐⭐⭐⭐⭐ It works! *by K***P on January 14, 2026* Replacement bulb works great! Love this lamp for my quilting room. ### ⭐⭐⭐⭐⭐ Quality product *by J***Y on March 27, 2026* It's the bulb I needed but the lamp quit ### ⭐⭐⭐⭐⭐ Fits the older OttLite floor lamp!!! *by C***E on January 10, 2025* Several years ago, I tried to find a replacement for my Ottlite Daylight gooseneck floor lamp, just to have a spare for when the bulb finally failed. I actually bought a couple of bulbs whose descriptions "promised" they would fit. But, they didn't -- not even close. Even the fabric store where I bought the light couldn't find compatible bulbs. I gave up the search. Luckily, the original bulb lasted more than 20 years (!). But, last week it finally failed, so my search began again. When I saw reviews for this bulb that referred to the OLDER Ottlite lamps, hope returned. This bulb FITS my Ottlite model U203030!!! It requires some careful muscle to push it in (it snaps sharply upon installation), but that's also true for the original bulb. If I could give this product 10 stars, I would. ## Frequently Bought Together - OttLite 18W Replacement Tube Light Bulb - Compact Fluorescent Light Bulbs Replacement - Bright Natural Daylight for Bedroom & Living Room - Low Heat & Glare Type B Light Bulb for Reduced Eyestrain - OttLite 24W Replacement Light Bulb - Energy Efficient Compact Fluorescent Light Tubes, Bright Natural Daylight for Bedroom & Living Room, Low Heat & Glare Type C Lightbulb for Reduced Eyestrain --- ## 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.kg/products/4077759-t18330-18w-daylight-cfl-replacement-tube-bulb-bulb-type-b](https://www.desertcart.kg/products/4077759-t18330-18w-daylight-cfl-replacement-tube-bulb-bulb-type-b) --- *Product available on Desertcart Kyrgyzstan* *Store origin: KG* *Last updated: 2026-05-28*
