The three primary types of color temperature for light bulbs are: Soft/warm White (2700K – 3000K), Cool/Bright White (3500K – 4100K), and Daylight (5000K – 6500K). The higher the Degrees Kelvin, the whiter the color temperature. Typically, most people prefer Warm White (WW = 3000K) bulbs for their homes. **Q: are 20 inch led fluorescent light tubes made?** A: I'm not aware of a 20" bulb and a quick internet search didn't reveal any. I've found measurements misleading to an extent. You might measure your old bulb. It might actually be a 21" bulb. It seems to me that the pins are often included in, or at least partially included, in the total measurement. **Q: is it slim?** A: Yes they are very slim. I purchased them for an under cabinet/over counter light fixture. **Q: Are the ends round? I bought one that the ends were oval & they won’t fit.** A: My ends are oval. ## Frequently Bought Together - KOR (Pack of 6) F13T5/CW - T5 Fluorescent 4100K Cool White - 13 Watt - 21" Super Long Life Light Bulbs - F8T5 Flourescent Light Bulbs - 12 inches Under Cabinet Bulb - Cool White 4100k 8 Watt Tube Bulb - Pack of 6 - KOR (Pack of 6) F8T5/CW - T5 Fluorescent 4100K Cool White - 8 Watt - 12" Super Long Life 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.tn/products/12863515-f13t5-cw-t5-fluorescent-tubes-13w-4100k-cool-white-6](https://www.desertcart.tn/products/12863515-f13t5-cw-t5-fluorescent-tubes-13w-4100k-cool-white-6) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-09-17*
