The base has plastic tabs that key it for different wattages, your light should have slots aligned to only take 13w (and possibly lower) bulbs. I think that the picture for this product is wrong, my 13w bulbs have the keys at 12 and 6 o'clock , and 18w has keys at 5 and 11. **Q: Can this replace a cooper r10 13w/4p?** A: If the base is 4 Pin G24q-1, then it will replace without a issue **Q: Is this for G24q-2 base or G24q-1? It says g24q-2 in the description, but the picture looks like a g24q-1.** A: G24q-2 as all 18watts are manufactured with the plastic piece sticking out on the bottom slightkh moved over from the center. **Q: Is this truly rated for outdoor use? The Amazon listing says it is, but the actual packaging makes no mention of outdoor use. And the website is dead.** A: I bought for indoor use so I can’t help you ## Customer Reviews ### ⭐⭐⭐⭐⭐ Good thing to get at Amazon *by on Reviewed in the United States June 27, 2026* My bathroom fan uses this bulb and Amazon is a good place to find them.They last about a year if you use them regularly. ### ⭐⭐⭐⭐⭐ Best fit *by on Reviewed in the United States March 28, 2026* Fit perfectly and was to bright ### ⭐⭐⭐⭐ Check the notch *by on Reviewed in the United States July 2, 2026* Great price, fast shipping, make sure the little plastic notch matches this one on this bulb. ## Frequently Bought Together - (4 Pack) PLC-18W 827, 4 Pin G24q-2, 18 Watt Double Tube, Compact Fluorescent Light Bulb, Replaces Sylvania 20683 and Philips 38329-9 - PL-C 18W/827/4P/ALTO - Sylvania 20669 26W Compact Fluorescent 4-Pin Double Tube 4100K 2-PACK --- ## 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.sc/products/28504241-circle-plc-18w-827-cfl-bulb-g24q-2-4-pin](https://www.desertcart.sc/products/28504241-circle-plc-18w-827-cfl-bulb-g24q-2-4-pin) --- *Product available on Desertcart Seychelles* *Store origin: SC* *Last updated: 2026-08-20*
