It's reddish color is similar to incandescent light bulbs, perhaps even more reddish-yellowish and severely deficient in blue which it renders nearly black. Also, the product picture does not show clearly the locking nubs on the flat sides of the plastic connector both sides. It didn't fit so I had to remove those nubs by cutting them off with a razor knife in order to insert the bulb into my Ott-Lite FlipBright lamp. Relatively inexpensive and it's brighter than the 9W one I had previously installed, but really a poor substitute for a genuine Ott-Lite bulb. Review: Vanity light - wish I had ordered a hotter white ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B003DIE7X2 | | Additional Features | Sylvania® 13 Watt 4-Pin Compact Fluorescent Bulb - 4,100 Kelvin - 800 Lumens - 10,000 Average Hour Life - 2GX7 Base - 6-1" Length- 82 CRI | | Best Sellers Rank | #327,035 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #1,676 in Fluorescent Tubes | | Brand | OSRAM SYLVANIA | | Brand Name | OSRAM SYLVANIA | | Bulb Shape Size | T | | Color Temperature | 3000 Kelvin | | Connectivity Technology | Normal bulb | | Control Method | App | | Controller Type | Push Button | | Customer Reviews | 2.9 out of 5 stars 5 Reviews | | Light Source Type | CFL, Fluorescent | | Light Source Wattage | 13 watts | | Light Type | Fluorescent | | Manufacturer | OSRAM SYLVANIA | | Manufacturer Part Number | CF13DS/E/830 | | Power Consumption | 13 watts | | Shape | 4 Pin base | | Special Feature | Sylvania® 13 Watt 4-Pin Compact Fluorescent Bulb - 4,100 Kelvin - 800 Lumens - 10,000 Average Hour Life - 2GX7 Base - 6-1" Length- 82 CRI Special Feature Sylvania® 13 Watt 4-Pin Compact Fluorescent Bulb - 4,100 Kelvin - 800 Lumens - 10,000 Average Hour Life - 2GX7 Base - 6-1" Length- 82 CRI See more | | Specific Uses For Product | Lamp | | Unit Count | 1 Count | | Wattage | 13 watts | ## Product Details - **Brand:** SYLVANIA - **Light Type:** Fluorescent - **Special Feature:** Sylvania® 13 Watt 4-Pin Compact Fluorescent Bulb - 4,100 Kelvin - 800 Lumens - 10,000 Average Hour Life - 2GX7 Base - 6-1" Length- 82 CRI - **Wattage:** 13 watts - **Bulb Shape Size:** T ## Images ![OSRAM SYLVANIA CF13DS/E/830 13W 2GX7 / 4-PIN TWIN TUBE Compact-Fluorescent - Image 1](https://m.media-amazon.com/images/I/31TcY-pv+XL.jpg) ## Customer Reviews ### ⭐⭐ Overly warm color, needed mod to fit my Ott-Lite *by J***D on January 5, 2026* I am disappointed that this turned out to be "warm white" apparently not 4100˚K as advertised.
